no output for graphics program

[ebindraj]

i don't get any output for even a simple program like drawing a line(i even tried the default example program in graphics)

whenever i run the program a blank screen appears
i have checked BGI files and all the required files are found...but still the problem persists
i get output for normal C programs(without graphics)

please please help me at the earliest

[sreenidhi88]

reinstall turbo c and try again.why dont you submit your program here.

this might help u
simplest c graphics program

check whether EGAVGA.BGI file is present...

#include<stdio.h>

#include<graphics.h>

int main()
{
int gd=DETECT,gm;
clrscr();
initgraph(&gd,&gm,"C:\\TC\\BGI");
circle(10,20,30);
getch();
}



i think u havn't enabled ur graphics library.............

do it frm

OPTIONS>LINKER>LIBRARY and check GRAPHICS LIBRARY option thr...........

if u do not enable GRAPHICS LIBRARY.............none of ur graphics prog will work......!!!!!!!!

buddy i have enabled the graphics library but still there is no output only a blank screen only appears
i'm posting the program as u said



#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
#include<graphics.h>
void main()
{
int gdriver = DETECT, gmode, errorcode;
initgraph(&gdriver, &gmode, " ");
setcolor(2);
line(100,200,250,200);
closegraph();
getch();
}

i tried this one also
#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
#include<graphics.h>
void main()
{
int gdriver = DETECT, gmode, errorcode;
initgraph(&gdriver, &gmode, "C:\TC\BGI ");
setcolor(2);
line(100,200,250,200);
closegraph();
getch();
}

i think you didnt read the link i gave.if c:\tc\bgi doesnt work try c:\\tc\\bgi.

[krishnandu.sarkar]

yup sreenidhi88 is rite........

"c:\tc\bgi doesnt work try c:\\tc\\bgi."

"c:\\tc\\bgi\\"

[j1n M@tt]

"c:\\tc\\bgi" will work.....or copy all necessary bgi files to the 'bin' directory of TC, or to the location where the C pgms r saved.

[ebindraj]

Buddy as u told me i copied all BGI files to BIN ..but stll no output comes only a blinking cursor is seen

this is the pgm ....



#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
#include<graphics.h>
void main()
{
int gdriver = DETECT, gmode, errorcode;
initgraph(&gdriver, &gmode, "C:\\TC\\BGI ");//(i tried C:\\TC\\BIN also)
setcolor(2);
line(100,200,250,200);
closegraph();
getch();
}

line(100,200,250,200);
closegraph();
getch();
}

no need of this step (i tried C:\\TC\\BIN also)
come back to C:\\TC\\BGI
dude you have any idea what closegraph() does??
and does it make any sense to call it before getch()??
your graphics program is working as expected.
use C:\\TC\\BGI itself
just thinkover once again about the sequence in which you call closegraph and getch()

[Garbage]

lol...

dude... call getch() before closegraph().

[Faun]

hahaha...lolz

btw TC sucks

[prasath_digit]

I tried ur prg in VC++ 2008 Express, but it looks like it doesn't support BGI graphics like TC( no "graphics.h" header file in the "C:\Program Files\Microsoft Visual Studio 9.0\VC\include" dir ). Currently i don have any other compiler installed on my PC, tommorow i'll try it on my friend's PC and post my solution.

Although, I also suggest Dev-C++ and VC++ 2008 Express Edition compilers, TC is the best choice for Simple programming.

[QwertyManiac]

Its not about the tool, its about the compiler that drives it and no matter how simple the code is, a compiler warning is always to be listened to, and errors cleared.
