Program for converting 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:
