Post ur C/C++ Programs Here

[Gigacore]

Hi guys n gals,

If you are a good at C/C++ Programming or if you are a programmer or just know this language then post you Programs here. By this way it helps learners a lot. Members can post their programs and get suggestions if there is anything wrong it......

Use this Pattern:

A Program to find the largest of three numbers using nexted if

#include <stdio.h>
main()
{
int a,b,c,big;
printf("Enter Three numbers");
scanf("%d%d%d",&a,&b,&c);
if(a>b)
if(a>c)
big=a;
else
big=c;
else
if(b>c)
big=b;
else
big=c;
printf("Largest of %d,%d and %d = %d",a,b,c,big);
return 0;
}

i've put up a lot more progs at my forum. classmates really find it useful since none of them is interested in computers. its so sad...

[max_demon]

My Program to calculate Addition

#include <stdlib.h>
main()
{
float a,b,c,total,multiply,add,input;
printf("Welcome to Demon Calculator \n\n");
printf("Enter the values-\n\n");
printf("a:");
scanf("%f",&a);
printf("b:");
scanf("%f",&b);
printf("c:");
scanf("%f",&c);

total=a*b*c;
if (total>80000)
printf("Meri Marzi , tu khud solve kar.\a\a\a\a\a\a\a\a\a\n\n");
else
printf("The answer is %f\n\n\a\a",total);
system("pause");
}

[Ron]

scanf("%d%d%d",&a,&b,&c);
New to c++.......Whta those this line means

[Yamaraj]

#include <stdio.h>
main()
{
int a,b,c,big;
printf("Enter Three numbers");
scanf("%d%d%d",&a,&b,&c);
if(a>b)
if(a>c)
big=a;
else
big=c;
else
if(b>c)
big=b;
else
big=c;
printf("Largest of %d,%d and %d = %d",a,b,c,big);
}
Your program lacks proper braces and a return statement.

here's a prog to calc area, surface area, volume, total surface area etc. of numerous 2D and 3D figures using functions

i had made this one for a friend - it was his project

Your code doesn't conform to either ISO C or C++ standards.

scanf("%d%d%d",&a,&b,&c);
New to c++.......Whta those this line means
scanf() is a C input function, which is considered unsafe except for formatted data. I advise learning C first, before opting for a much larger, bloated and complex language as C++.

[fun2sh]

+no the program is correct dude

[Gigacore]

i added the return statement, is it rite now?

[Pathik]

scanf("%d%d%d",&a,&b,&c);
New to c++.......Whta those this line means
y r u using scanf in c++???

^^this is totally wrong what if b>c>gr8test there's no condition to test that

use this thread to request programs and then pm to the requester rather than posting so much code over here it really looks a mess and these are quite basic too

[Gigacore]

@ utsav... did it execute buddy?

[Yamaraj]

^^this is totally wrong what if b>c>gr8test there's no condition to test that
Rules of programming:
1. Read the fscking code. And mine is pretty readable.
2. Test it before complaining.
3. If you still don't get it, it's time to buy a decent C book.

[xbonez]

@yamraj : what was wrong with my prog?? :( it seemed to run perfectly fine

@yamraj : what was wrong with my prog?? :( it seemed to run perfectly fine
Using implementation dependent libraries and functions like clrscr(), and the nonstandard "void main()" violates the rules of the ISO C++ standard. Your executable may run fine on a system, but your code needs more love.

I recommend a decent and recent C++ book, like C++: How To Program, C++ Primer, 4th/e or C++ Primer Plus.

[utsav]

@ gigacore it executed nicely on devc++. tell me the problm with my program

[Sykora]

And for heaven's sake indent the code like the first post. It's unreadable otherwise.

[Gigacore]

Program To Reverse a Number

#include <stdio.h>
main()
{
long rev, n, num;
int digit;
printf("\n Enter a number");
scanf("%d", &num);
rev=0;
n=num;
while (num>0)
{
digit = num % 10;
num = num / 10
rev = rev * 10 + digit;
}
printf("\n The number is %d", n);
printf("\n The reverse is %d", rev);
}

[mehulved]

And how about using comments in the code so people like me could understand it faster and better.

[utsav]

^^ i hav used comments in my program

[Gigacore]

use /* before the coment

[shady_inc]

use /* before the coment

....and */ after the comment.

can someone tell me what's wrong in this program.Using Dev C++

#include <iostream>
#include <conio.h>

[Sykora]

@shady_inc :
conio.h is non-standard.
Your calsum() doesn't have a forward declaration. Put main() after calsum() or put the line :

int calsum(float, float);

before main().

[Gigacore]

does any know how to write this one?

Write a program using functions to find whether the given number is a prime number?

[ilugd]

do an iteration from 2 to int(n/2) and if it isn't divisible then it is prime.

[Yamaraj]

Either Sykora's solution or simply add a float to your function definition line:

#include <iostream>
using namespace std;
int main()
{
/*Use of Function*/
float a,b,sum;
float calsum(float a,float b);

cout<<"Enter the two nos.:\n";
cin>>a>>b;

float calsum(float a,float b)

float sum;

sum=a+b;

return (sum);

bad math funda :D .. iterate from 2 to (int)sqrt(n) ..if it isnt divisible then itz prime

How to Program in C++ by Deitel and Deitel is good too


I find books by Yashavant Kanetkar the best ones for C/C++.

And as far as Kanetkar is concerned ... when I was inmy 11/12th I thought so too. But now, :D u jst mature. Those books feel like being fed with a spoon.

They do contain a LOT of funda though

i got 33% in my math exams during my bachelor's degree. Don't know how i lost it. Got 98% in +2 though. Come to think of it, I was socializing, eating and drinking the whole 3 years in BCA (if you know what I mean). :-D

PLz tell me what about this program and what it will do, i know stack but plz explain

I have new idea..!!!!

What about some challenges any one can raised problem, before 2 days my teacher challenge me to do a program to convert given number into binary , octal and hexadecimal. I have found solution but you have to try.

for exercise:

do a program like U have to hide the typed string on screen by" * "

like we do password: **********

nice one haa..

[QwertyManiac]

Stack is a simple Last-In First-Out data structure .. Its like this:

http://upload.wikimedia.org/wikipedia/commons/2/29/Data_stack.svg|20|
|30|
|40|
----

To add an element to it, we can only push from top and not insert anywhere we like:

So after pushing 10 into the stack, it looks like:

|10| <-- (Pushed on top)
|20|
|30|
|40|
----

Similarly, as its a LIFO system, Popping the stack removes the top most element.

Thus, 10 would be removed on popping:

|20| --> |10| (Popped out and deleted)
|30|
|40|
----

Stack's best application would be the function call. Recursion takes place in stacks format. (And are thus usually avoided)

[Zeeshan Quireshi]

hmm, u use Oxford and Sumita Arora's textbook for C++. they're our course books in XI and XII
Mate i suggest you re-learn C++ using Addison Wesley's Accelerated C++

One of the best Standard C++ books out there that actually teach you how to use STL practically rather than just theory.

btw , i read this in class XI(i'm currently in XII) so ditch your textbook(seriously) and use this .

[king khan]

does any body had a c++ code to shut down the system

[QwertyManiac]

Isn't that as simple as calling the DOS shutdown function via the system function?

Like system("shutdown /?"); for example.

Why would you wanna do it though ? I smell a prank :D

That is one helluva program which I made 2-3 months back but my program was not perfect as I used a lot of arrays which took up a lot of memory and more often than not they were never used.I seem to have lost my original program code but will write it and post it in a couple of days or so.

YOu can actually display the given no. in octal,hexadecimal,and binary by just using %o,%x,and(I forgot for binary) instead of %d while displaying.

A bulls and cows game.I am still working on this. Trying to add some more functionality.

I know the variable names are quite big. But I think that makes it easier to understand the program without comments.

I am new to C++. So, if you can suggest any improvements, then please do so.

One more thing, from my experience, Indian authors tend to provide knowledge based on TurboC which sucks. So, anyone going for a C++ course, please get a book suggested above, and then be sure to read professional C++ by Solter and Kleper (Wrox international). It rocks.

I don't know python but dude the program seems to just display the no. in corresponding number system.But here we were talking about actually converting the no. so that we can even use them in arithmetic operations.

The c equivalent of your program is(I am just writing the necessary part):

Printf("Enter the decimal no.:");
scanf("%d",&n);
printf("The equivalent octal no. is:%o\n\n The equivalent hexadecimal no. is %x",n,n);
getch();


The trick is just to replace %d by %o and %x while displaying.
I didn't check it but hope this works.

@qwerty please pardon me if I was unable to interpret your python program properly.BTW I am also planning to learn python very soon.So how is compared to C(I am good at c).

[Sykora]

@qwerty : A few observations,
-- Use ''.join or (' '.join in your case) instead of string += something. It's faster.
For example,

def strtodec(a) :
return ' '.join((ord(i) for i in a))

and likewise.
-- Put your docstrings below the function def, not above them.
That's all I can get from the first few of them.

Why do you find converting ASCII to hex and octal necessary?

@The_Devil_Himself :
The internal representation of numbers in most languages is in decimal. In C/C++ you can perform arithmetic in octal and hex by prefixing a 0 or 0x to an int declared variable. However, for other bases, you will have to define your own class and overload your own operators to make it work as seamlessly as you'd like.

Python is a much more elegant language than C. It is a dynamically typed language, and heavily object oriented. It also has one of the largest standard libraries. It pays for all this in a severe lack of speed on most number crunching applications.

Oh ok, I've just started off actually, am not so strong in it. I'll keep that point in mind. And about the usefulness, I don't know, I just wrote something huge .. practising stuff.

what abt licenses of all these codes ;) :D :)) GPL? Open Source License with credit given to Original authors.I'd love to post,but what am weak in Math :(

[shady_inc]

A bulls and cows game.I am still working on this. Trying to add some more functionality.

I know the variable names are quite big. But I think that makes it easier to understand the program without comments.

I am new to C++. So, if you can suggest any improvements, then please do so.

One more thing, from my experience, Indian authors tend to provide knowledge based on TurboC which sucks. So, anyone going for a C++ course, please get a book suggested above, and then be sure to read professional C++ by Solter and Kleper (Wrox international). It rocks.

How do i play this game.What do I do after pressing Enter the first time??

[aditya.shevade]

^^It is a standard bulls and cows game. The computer selects a number. A 4 digit number. There are no repeated digits in the number. Each digit is unique.

here This is a single player game. The computer selects a 4 digit number at random and then you have to guess that number. Remember that each digit in the number selected by the computer will be unique. Then when you enter your choice, the computer will give an output which will be telling you the total number of digits and positions of those which are correct.

Suppose the computer has selected the number 2156, and you enter your guess as 1234. Here the numbers 1 and 2 are correct. The positions of those numbers are, however, not correct. So the output will be:-

2 Numbers Correct.

0 Positions Correct.

Now if you enter 2134 then the output will be:-

2 Numbers Correct.

2 Positions Correct.

Now if you enter 2156 as your number, then all four numbers as well as their positions are correct, so the output will be:-

The number Selected By the computer was 2156

i've heard ders a program to curupt da HDD....its a 3 line code....and same program can make HDD workin again...does ne one know it??

[The_Devil_Himself]

Abhishek nothing can corrupt your hard disk what can a program can maximally do is format your hard disk.

[QwertyManiac]

You can write programs to corrupt drives, but I don't know of a 3 line method. It sounds ineffective and lazy. I've heard of virii damaging the firmware of your HDD rather than doing something to the HDD itself, that's clever. Though accessing the firmware is a big job!

^ Ya its very difficult

[mavihs]

can u guys give me a site where i can reffere about c++ & get some solution. & i got this a prob with a question i hav. if u guys can solve it or give a hint or anything.
here it is:-

WAP to display th following format on the screen.(using loop)

1
1 1 1
1 1 1 1 1
1 1 1 1 1 1 1



plzzzzzzz give the ans or atleast some hint or somthing. I got an exam on monday. i hav 2 prepare for it. i can't understand these question how 2 do. plzzzzz help! i've been trying 2 figure it out for a week. it may come for my exam. plzzzz help!!!!!!

[Gigacore]

Try this:

#include <stdio.h>
main()
{
int row, col, t, i;
int tab=40;
for(row = 1; row <= 7; row++)
{
for (t = 1; t <= tab; t++) printf(" ");
/* number if blank spaces from left edge of the screen */
for(col = 1;col <= row; col++)
printf("%d ",row);
printf("\n");
tab--;
}
return 0;
}

For C++ tutors...: http://www.cprogramming.com/tutorial.html

[Projjwal]

do u know wht's the output of following prog
:)) :))

#include<stdio.h>
#include<conio.h>
void main()
{
int c;
c=printf("abc");
printf("\n%d",c);
getch();
}
Don't run it. Just guess it's output . & why?

[QwertyManiac]

Try this:

#include <stdio.h>
main()
{
int row, col, t, i;
int tab=40;
for(row = 1; row <= 7; row++)
{
for (t = 1; t <= tab; t++) printf(" ");
/* number if blank spaces from left edge of the screen */
for(col = 1;col <= row; col++)
printf("%d ",row);
printf("\n");
tab--;
}
return 0;
} He needed just 1s and in odd quantities only. :p Good write up though :)

[ilugd]

what does printf return by the way? a return value or some pointer? It would take a minute to google that but I guess that would be cheating. :-)

[QwertyManiac]

what does printf return by the way? a return value or some pointer? It would take a minute to google that but I guess that would be cheating.

I think it returns an int. I've seen int in its prototype for sure. But I got no clue what the output of Projjwal's program's gotta be.

[Projjwal]

hint:





try it bro....u r partially correct ..It's the value which printf return..But wht is that value.? I give up the ans is
abc
3

Honestly Speaking this is going to be my fevorite thread ever on Digit forum...
BookMarked...


OK, let me post my Today's Homework here..hehe...

Write a [I]C Program to sort numbers of an Array using Bubble Sort Method.

#include <stdio.h>
#define MAX 10
void swap(int *x,int *y)
{
int temp;
temp = *x;
*x = *y;
*y = temp;
}
void bsort(int list[], int n)
{
int i,j;
for(i=0;i<(n-1);i++)
for(j=0;j<(n-(i+1));j++)
if(list[j] > list[j+1])
swap(&list[j],&list[j+1]);
}
void readlist(int list[],int n)
{
int i;
printf("Enter the elements\n");
for(i=0;i<n;i++)
scanf("%d",&list[i]);
}

void printlist(int list[],int n)
{
int i;
printf("The elements of the list are: \n");
for(i=0;i<n;i++)
printf("%d\t",list[i]);
}

void main()
{
int list[MAX], n;
printf("Enter the number of elements in the list max = 10\n");
scanf("%d",&n);
readlist(list,n);
printf("The list before sorting is:\n");
printlist(list,n);
bsort(list,n);
printf("The list after sorting is:\n");
printlist(list,n);
}



^ theres nothing in Hint

There IS..
Just Highlight the post.

[Projjwal]

yea just highlight my previous post or just press "ctrl+ A ".Actually printf is a function with return type integer .Just open stdio.h file from include directory frm there u will got that. And it returns the length of string which it print.so as a result
c=printf("abc")
means printf return value 3 Which saved in C integer variable thats all.

[Gigacore]

Cool Projjwal, thanks Quiz Master :D

[Projjwal]

So,everybody of the forum know swapping using 3rd variable & without 3rd variable .now write a swapping program in c without 3rd variable & de vital point is use one line function only .
means
b=a+b;
a=b-a;
b=b-a;
---------------de above program has 3 functional lines now write it in one functional line.

[The_Devil_Himself]

^^eh..how do we do that?

[aditya.shevade]

Easy. Check this out.

#include<iostream>

using namespace std;

main()
{
int a, b;

cout << "Enter A and B" << endl;
cout << "a = ";
cin >> a;
cout << endl << "b = ";
cin >> b;

a = ((b - a) + (b = a));

cout << endl << "a = " << a << endl;
cout << "b = " << b;

return 0;

}

EDIT : Output :-

EXECUTING:
/home/aditya/test

Enter A and B
a = 12

b = 23

a = 23
b = 12

Dev C++ too? Doesn't the output remain in the console box? Anyway for TC++ you need to call getch(); just before the end of the main function ( Before } ) but I guess you'd definitely know that :confused:

You mean to say that you get the output but not the final result or does it end abruptly in middle (Segmentation fault?)

[Nav11aug]

I think he means that he cant see the output, nt terminating in the middle of smthin. Program completes execution and closes window

@aditya.shevade It's very cool ans.Gr8 job ...I was just looking for this ans.
Now do the same thing without using "()" .

It will require a whole app to be coded not just a single C++ program.

@Batistabomb i think it's not so easy . U have to develop a C++ program with directX .So u have to know directX programming in other language like VB.NET,C#.net DirectX programming r easier then C++.

That swapping thing cost me 6 marks in an exam last year (In C). The teacher refused to believe it works, and when I showed it in the lab, she said its not the right way to do it :| People ..

@Batistabomb - Projjwal is right I guess, .Net would be the easiest way, using Microsoft's APIs. Anyway check these links, I got no idea how to use them though.

That swapping thing cost me 6 marks in an exam last year (In C). The teacher refused to believe it works, and when I showed it in the lab, she said its not the right way to do it :| People ..


nthn surprisin.. people(especially teachers) dnt appreciate the smart ways of doin things.. got many marks cut when in school fr using KeyB shrtcuts everywhere in Office :((

[The_Devil_Himself]

I couldn't agree more.In many a cases students are way smarter than teachers.Today my Data structure was asking "hey how do we change resolution in linux(red hat)?" and I was laughing like hell.

Hey guys(and gals of course) don't you think this thread should be made a sticky?The starter please start a poll man--sticky or not sticky.

Here's something useful with respect to this thread.

This program creates a vB list out of a file given in a particular format.

The format should be:

Title 1
URL 1
Title 2
URL 2

And the output file's content will be the vB code for the following:


List Title

:arrow: Title 1 (http://URL%201)
:arrow: Title 2 (http://URL%202)Would be helpful for those maintaining List threads. And it'd be good if Intel_Gigacore maintains it for this thread too.

Am uploading an example file along, which contains the list for this thread.

And here's the code. Briefly Documented.

Edit: Code removed as the tags inside were getting converted.
Code's attached as digit.txt.

Download digit.txt below to view code.
You can rename it to digit.cpp.
Sorry for the inconvenience
Note: You might find an extra LIST tag at the end of the file but that's cause of the editors. The editors place an extra line at EOF, so can't help it.
I can add a lot of BACKSPACE characters but that's just stupid. So till I find another workaround, this is the code.

title.txt is the input test file.
digitout.txt is the test output file.
digit.txt is the code file. Rename it to digit.cpp to get syntax highlighting.

digitout.txt when pasted here, will look like:

And here's a sample run. Forgot to add it to the earlier post.


harsh@qwerty-workstation:~$ ./digit.out

Digit Forum URL Bulleted List Generator
-------------------------------------

Version 1.0

The Input file must be in the format of Title first and URL next.

Example:
Title1
http://URL 1
Title 2
http://URL 2

And so on..

Enter the input file's location and name to convert: title
Enter the output file's location and name to store into: digitout
Enter the list name: Programs
harsh@qwerty-workstation:~$


This'd hopefully work in Windows as well. As I haven't added any OS-only code. :)

[aditya.shevade]

^^ better algo than the one given..

11 @aditya.shevade

Uhh... better than one given where? Please explain what do you mean.

@aditya.shevade It's very cool ans.Gr8 job ...I was just looking for this ans.
Now do the same thing without using "()" .

use Bitwise Operators
--------------------------------------------------------------
#include<stdio.h>

#include<conio.h>
void main()
{
int a,b;
a=12;
b=25;
a=((b-a)+(b=a));
printf("\na:%d\nb:%d",a,b);
getch();
}

This is de C version of aditya.shevade run it.
-----------------------------------------------------------

Alright... Will do that... Right now, gotta run for keyboard class (music).


This is de C version of aditya.shevade run it.

Oh.... I have a C version of myself now... Didn't know that one :-D

By the way. Had my C orals today. Mid Semester exams. Scored 23/25. Topped the batch of 20 :-D. Orals of remaining 3 batches are still to be held. :-D

Aditya

[QwertyManiac]

Orals? :p What are we supposed to do in Orals? :?

Btw, swapping in Python is deadly easy :))

a,b=b,a

That's it, swapped. :))

Here's a running example:

harsh@qwerty-workstation:~$ python
Python 2.5.1 (r251:54863, May 2 2007, 16:56:35)
[GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a=25
>>> b=10
>>> a,b=b,a
>>> a
10
>>> b
25
>>> exit()
harsh@qwerty-workstation:~$

[Nav11aug]

Uhh... better than one given where? Please explain what do you mean.

better than b=a+b;
a=b-a;
b=b-a;
---------------de above program has 3 functional lines now write it in one functional line.
the implementation did not use the line b=a+b.thz why i said "better"

[Quiz_Master]

Hey QWERTY.. That program in Post #92 is awesome man...
ThankQ Very Much for that....

[Nav11aug]

Hey guys(and gals of course) don't you think this thread should be made a sticky?The starter please start a poll man--sticky or not sticky.

Sticky now ..sweet :)

[QwertyManiac]

It isn't sticky yet :?

I don't want this as sticky, cause no one would look at it then, as is the case with most stickies. I'd rather vote for a new Programming section :)

[Quiz_Master]

This was today's homework.

Write a C program to find an element from an Array using Binary Search Method.


#include <stdio.h>
#define M 10

void bsearch(int list[],int n,int element)
{
int l,u,m, flag = 0;
l = 0;
u = n-1;
while(l <= u)
{
m = (l+u)/2;
if( list[m] == element)
{
printf("The element whose value is %d is present at position %d in list\n",element,m);
flag =1;
break;
}
else
if(list[m] < element)
l = m+1;
else
u = m-1;
}
if( flag == 0)
printf("The element whose value is %d is not present in the list\n",element);
