Automorphic Number:

Write a C++ program that prompts the user to enter a positive integer n and checks whether n is an automorphic number or not. An automorphic number is a positive integer that evaluated to the power of another number k ends with the same n, test for k = 2, 3, , 10. For example, 5 evaluated to 2 produces 25 which ends with 5, so 5 is an automorphic number. The integer 76 is automorphic since 764 = 33362176.

Sample input / output: Enter a positive integer: 43 43 is automorphic for 5
