On most systems, you'd have to be trying fairly hard not to find '<stdio.h>
', to the point where the first reaction is "is <stdio.h>
installed". So, I'd be looking to see if the file exists in a plausible location. If not, then your installation of Turbo C is broken; reinstall. If you can find it, then you will have to establish why the compiler is not searching for it in the right place - what are the compiler options you've specified and where is the compiler searching for its headers (and why isn't it searching where the header is).
