c program to find prime number

c program to find prime number. In this C program, we will input the number when program runs and find whether that entered number is prime or not. You can also refer for co- prime numberThis program uses “%” or “modulus” operator which gives the remainder of two numbers when it is divided. We can also find prime number using recursion.
