Using functions, write a program in C++ to find out whether a given number is a palindrome or not. A palindromic number is a number (in some base ) that is the same when written forwards or backwards. The first few palindromic numbers are therefore are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101,111,121 etc.
