Write a function called totalSeconds() that takes three int values - for hours, minutes and seconds - as arguments, and returns the equivalent time in seconds (type long). Create a program that does above task repeatedly until user hits 'N' or 'n' from keyboard.

 Here's a C++ program that includes the totalSeconds() function and a loop to repeatedly ask the user for input until they enter 'N' or 'n':

#include <iostream>

using namespace std;

long totalSeconds(int hours, int minutes, int seconds) {
    return hours * 3600 + minutes * 60 + seconds;
}
int main() {
    char repeat = 'Y';
    while (repeat == 'Y' || repeat == 'y') {
        int hours, minutes, seconds;
        cout << "Enter time in hours, minutes, and seconds: ";
        cin >> hours >> minutes >> seconds;
        long totalSecs = totalSeconds(hours, minutes, seconds);
        cout << "Total seconds: " << totalSecs << endl;
        cout << "Do you want to calculate again? (Y/N): ";
        cin >> repeat;
    }
    return 0;
}

Output:

Enter time in hours, minutes, and seconds: 3 15 30
Total seconds: 11730
Do you want to calculate again? (Y/N): y
Enter time in hours, minutes, and seconds: 2 0 0
Total seconds: 7200
Do you want to calculate again? (Y/N): n

Explanation:

• The program includes the totalSeconds() function, which takes in three integer arguments representing hours, minutes, and seconds and returns the total number of seconds as a long integer.
• The main() function includes a while loop that continues until the user enters 'N' or 'n'. Inside the loop, the program prompts the user to enter values for hours, minutes, and seconds using cin, then calls the totalSeconds() function to calculate the total number of seconds and displays it using cout.
• After displaying the result, the program prompts the user to enter whether they want to calculate again or not. If the user enters 'Y' or 'y', the loop continues; otherwise, the program exits.
• The loop continues to run until the user enters 'N' or 'n', allowing the user to calculate the total number of seconds for multiple sets of input.
