C++ Exercises: Convert a given number into hours and minutes

Sample Solution:

C++ Code :

#include <iostream>
#include <string>
using namespace std;

// Function to convert a number to hours and minutes
void Time_Convert(int num) {
    bool flag; // Flag to control loop
    int hr = 0; // Initialize hours to 0

    do {
        flag = false; // Set flag to false initially

        if (num >= 60) {
            hr++; // Increment hours
            num -= 60; // Subtract 60 from the number
            flag = true; // Set flag to true to continue the loop
        }
    } while (flag); // Continue loop until flag is false

    // Print the converted time in "H:M" format
    cout << "\nH:M " << hr << ":" << num << endl;
}

int main() {
    // Function calls to convert different numbers to hours and minutes
    Time_Convert(67);
    Time_Convert(60);
    Time_Convert(120);
    Time_Convert(40);

    return 0;
}

Sample Output:

H:M 1:7

H:M 1:0
