C Program to Convert Hours into Minutes and Seconds

Given an integer n which is the number of hours, the task is to convert it into minutes and seconds.

Examples:

Input: 5 
Output: Minutes = 300, Seconds = 18000

Input: 2 
Output: Minutes = 120, Seconds = 7200 

Approach:

• h hours = h * 60 minutes as 1 hour = 60 minutes.
• Similarly h hours = h * 3600 seconds.

Note: To convert m minutes back into hours, do n / 60 and for s seconds s / 3600.
Below is the implementation of the above approach: 

C

// C program to convert hours
// into minutes and seconds
#include <stdio.h>

// Function to convert hours
// into minutes and seconds
void ConvertHours(int n)
{
    long long int minutes, seconds;

    minutes = n * 60;
    seconds = n * 3600;

    printf("Minutes = %lld, Seconds = %lld
",minutes,seconds);
}

// Driver code
int main()
{
    int n = 5;
    ConvertHours(n);
    return 0;
}

Output:

Minutes = 300, Seconds = 18000
