What The Difference between stdio.h and iostream?

<iostream> is the C++ header for the input / output classes and objects (std::cout, std::cin...).
<stdio.h> is the C header for printf, scanf, ...
In C++, <stdio.h> became <cstdio>

In C++, you are not supposed to use <stdio.h>, use <iostream> instead.
