12-hour clock


Did You Know?

The 12-hour clock is a time convention in which the 24 hours of the day are divided into two periods: a.m. (from the Latin ante meridiem, meaning “before midday”) and p.m. (post meridiem, “after midday”). Each period consists of 12 hours numbered: 12 (acting as zero), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11. The 24 hour/day cycle starts at 12 midnight (often indicated as 12 a.m.), runs through 12 noon (often indicated as 12 p.m.), and continues to the midnight at the end of the day.

24-hour to 12-hour clock convertor

Your challenge consists of writing a computer program that asks the end-user to enter a time in the 24-hour format (e.g. 18:36). The program will convert this time in the 12-hour format (e.g. 6:36 PM).



Amend this code to validate the user entry and make sure they enter a time between 00:00 and 23:59 and to display an error message if not.
