C++

Skills needed to complete this assignment:conditionals ,loops and functions.The keypad on your oven is used to enter the desired cooking time and is arranged like the digits on a phone.

1	2	3
4	5	6
7	8	9
	0

Unfortunately, the circuitry is damaged and the digits in the leftmost column no longer function. In other words, the digits 1, 4, and 7 do not work. If a recipe calls for a time that cant be entered, then you would like to substitute a time that can be entered. Write a program that inputs a desired time . The cooking time must be between 00:01 and 09:59. If the desired time does not contain 1, 4, or 7, then output the desired time. Otherwise, compute the next longer time that does not contain 1, 4, or 7 and output

it. If the desired time is invalid (time is not between 00:01 and 09:59, or the minute argument is greater than 59), the program outputs error messages.

Example 1:

Input:

00:20

Expected output:

00:20

Explanation:

The desired time does not contain 1, 4, or 7.

Example2:

Input:

00:01

Expected output:

00:02

Example3:

Input:

00:47

Expected output:

00:50
