# C program to check whether number is Prime or Not

This program will **read an integer number and check whether it is Prime number of not**. *Primer Numbers are those numbers which divides by itself*, for example 19 is a Primer Number because it can be divided by 19 Only.

To check number is prime or not, we will divide numbers from 2 to Number/2 in a loop. If it is divisible by any number between the 2 to 19/2, number will not be primer but here 19 will not be divided so it is a prime number.
