cout, cin etc. take part from library. You must include it to get the program work

if you want to compile with gcc, you should use printf instead of cout, scanf instead of cin and fprintf instead of fout.

std::cin and std::cout are in <iostream>. Please include that, and compile your C++ code with g++, not gcc - otherwise you'll get all sorts of linking issues.

You need to

#include <iostream>

as well.

Also, compile the file with g++ instead of gcc.
