do you have EGAVGA.BIG present in BGI folder?

[Zu007]

yes present

[Akshit]

ok then do you have graphics library enabled?There are four library setups in turbo c 3.0

I had problem with same some time ago.

[Akshit]

then check if graphics library is enabled or not?Don't know procedure do check/do it.Just google it.

In Turbo c 3.0 you need to enable it.I had same problem some time ago.

Also I suggest you to move to newer IDE.Maybe Visual C++ version 8 or 10 or 12
