Write a C program to find whether a given number is a Kaprekar number or not

Question

Consider an n-digit number k. Square it and add the right n digits to the left n or n-1 digits. If the
resultant sum is k, then k is called a Kaprekar number. For example, 9 is a Kaprekar number
since 92 = 81 & 8+1=9
and 297 is a Kaprekar number since 2972 = 88209 & 88+209 = 297.
Write a C program to find whether a given number is a Kaprekar number or not.
