(a) Write a C++ program that asks the user to enter up to a 5-digit positive integer number and then reverses the order of the digits. The program outputs both numbers and their square roots. An example of the execution of the problem is shown below. Your program should work for 5-digits, 4-digits, 3-digits, 2-digits and 1-digit.

Please enter a 5-digits integer: (user inputs 12345) The square root of 12345 is: 111.108
The number in reverse is: 54321
The square root of 54321 is: 233.068

(b) ( extra credit – 5 pts) Find a 5-digit number that reverses the order of its digits when multiplied by 4.
(c) (extra credit – 5 pts)) How many 5-digits numbers are there in which the sum of the digits is even.
