Question

Write a script that inputs integers (one at a time) and passes them one at a time to function isEven. which uses the modulus operator to determine whether an integer is even. The function should take an integer argument and return true if the integer is even and false otherwise. Use sentinel-controlled looping and a prompt dialog.

Answer 1

#include <iostream>
using namespace std;

bool isEven(int num) {
    return num % 2 == 0;
}

int main() {
    int num;
    do {
        cout << "Enter a number(-99 to exit): ";
        cin >> num;
        if (num != -99) {
            if (isEven(num)) {
                cout << num << " is even." << endl;
            } else {
                cout << num << " is odd." << endl;
            }
        }
    } while (num != -99);
    return 0;
}
