Getting fatal error when including <stdlib>

Question

I got a fatal error that the file or directory <stdlib> is not found on ubuntu 11.xx when I typed #include <stdlib>.

Is <stdlib> deprecated/removed, or is there something wrong with my GCC installation?

Answer 1

In C++ code, include 'cstdlib' instead.

#include <cstdlib>

If you are using C, include 'stdlib.h'

#include <stdlib.h>

In c++ code, always prefer the cXXX include instead of XXX.h
