Don't u know the way of an error if so put error msg here

Content of my file 'abc.cpp'

#include<iostream.h>
void main()
{
int a,b;
cout<<"Enter numbers : ";
cin>>a>>b;
cout<<"Sum : "<<a+b;
}

The command I trigger to compile the code :

$ gcc abc.cpp

Error Message:

^^^
Plz give me a solution Piyush i m waiting for a reply

Note a minor change in code:

#include<iostream.h>
int main()
{
int a,b;
cout<<"Enter numbers : ";
cin>>a>>b;
cout<<"Sum : "<<a+b;
return 0;
}

But still not working

Sorry for late reply

This link solves ur problem

Use g++ for C++ files

#include <iostream>

using namespace std;

int main() {
cout << "Hello, world!" << endl;
return 0; // No error
}

g++ -o helloworld helloworld.cpp

u can refer this page for tutorial on c and tutorial on data stucture.
http://www.desi-tek.com/forum/index.php?act=SF&s=&f=35
i wrote that tutorial long time back when i was studying c

[anantkhaitan]

Thanks Piyush for the link now I m able to compile with 'make'
I want to share this example with u all

Code:

#include<iostream>
int main()
{
int a,b;
std::cout<<"Enter numbers : ";
std::cin>>a>>b;
std::cout<<"Sum : "<<a+b;
return 0;
}

save the file as abc.cpp
and run the following commands

$ make abc

then

$ ./abc

thats all
