#include <iostream>

using namespace std;

int main() {

    bool prop;//creates boolean variable named prop

    prop = (5>1); //assigns prop to 1. This is because 5>1 is a true statement and true is represented with 1 in c++. False if represented by 0.

    cout<<"prop is "<<prop<<endl; //outputs string "prop is " followed by 1

    prop = (1>5); //assigns prop to 0

    cout<<"prop is "<<prop<<endl; //outputs string "prop is " followed by 0

    prop = (1 != 5); //assigns prop to 1

    cout << "prop is " <<prop<<endl; //outputs string "prop is " followed by 1

    return 0; //exits program

}

Output:

[cms-opendata@localhost src]$ ./a.out

prop is 1

prop is 0

prop is 1
