Sunny Number Program in C1 min read

Let us go through a C program to check whether the number is Sunny Number or Not.

What is Sunny Number?

A number N is said to be a sunny number if the number next to the given number (N+1) is a perfect square.

Example: Let us take a Number 8, then the next number is 8+1=9 and as 3 is a square root of 9, hence 8 is a sunny Number.

Another example, let the number be 5, then 5+1=6, that has no square roots, hence 5 is not a sunny Number.
