Convert seconds into hours, minutes, seconds

Write a C program to convert a given integer (in seconds) to hours, minutes and seconds.

Pictorial Presentation:

C Code:

#include <stdio.h>
int main() {
    int sec, h, m, s; // Declare variables for seconds, hours, minutes, and seconds
    
    // Prompt user for input seconds and store in 'sec'
    printf("Input seconds: ");
    scanf("%d", &sec);
	
    // Calculate hours, minutes, and remaining seconds
    h = (sec/3600); 
    m = (sec -(3600*h))/60;
    s = (sec -(3600*h)-(m*60));
	
    // Print the time in format H:M:S
    printf("H:M:S - %d:%d:%d\n",h,m,s);
	
    return 0;
}

Sample Output:

Input seconds: 25300                                                   
H:M:S - 7:1:40
