Write a C program to read any integer from user and compute the reverse of given number. Also output whether the reverse number is prime or not.

Write a C program to read any integer from user and compute the reverse of given number. Also output 
whether the reverse number is prime or not. Sample Input/Output: 
Enter any integer: 4521
Reverse number is: 1254. It is not a prime number.
