What The Difference between stdio.h and iostream? [duplicate]

Question

#include<stdio.h>
int main ()
{
    // code
}
return 0 ;

#include<iostream>
int main ()
{
    // code
}

Which library is best to use?

What is the best and why? And when I code what is the difference in function between them?

Answer 1

stdio.h is the header file in the C standard library. It is used for input/output

iostream is the input output class in C++

So if you're using C++ just use #include <iostream>

Answer 2

First off, iostream is part of the C++ standard library, and stdio.h is part of the C standard library. While stdio.h will work in C++ it does not provide everything that iostream includes as iostream is specifically for C++.

Here is stdio.h documentation.

Here is iostream documentation.
