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: ";

cin>>x>>y;

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

 

return 0;

}

 

Output example:

 

Enter two integers: 77 71

77 is not equal to 71

Press any key to continue . . .

Enter two integers: 11 11

11 is equal to 11

Press any key to continue . . .
