#include iostream in C?

Question

In C++ we always put the following at the top of the program

#include <iostream>

What about for C?

Answer 1

Well, this is called the standard I/O header. In C you have:

#include <stdio.h>

It's not an analog to <iostream>. There is no analog to iostream in C -- it lacks objects and types. If you're using C++, it's the analog to <cstdio>.
