# 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.

## Program to check whether the number is Sunny Number or Not.

Output:

`Enter the number: 1616 is a sunny number.`

## Display all the sunny number within a range of 0 to 100 in C programming

Output:

`List of sunny number from 0 to 100 range:149162536496481`
