#include<iostream> is a header, it allows you to use the default library, iostream. namespace std allows you to call iostream w/o using the keyword 'std' all the time.

try removing "using namespace std" in your codes. run it. Then after that, add "std::" in front of your cout and cin, then you get what I meant.
