When i compile this program i get the following errors.

stdfile.cpp: In function 'int main()':
stdfile.cpp:12:1: error: 'cout' was not declared in this scope
stdfile.cpp:13:1: error: 'cin' was not declared in this scope

Answer 1

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.
