To show: How to use cin to read integers from standard input in C++ programming


// the stream extraction operator variation of cin

#include <iostream>

using namespace std;


int main(void)


int x, y;


cout<<"Enter two integers: ";


cout<<x<<(x == y?" is " : " is not ")<<"equal to "<<y<<endl;


return 0;
