Prime Number program in C25 Mar 2025 | 1 min read Prime number in C: Prime number is a number that is greater than 1 and divided by 1 or itself. In other words, prime numbers can't be divided by other numbers than itself or 1. For example 2, 3, 5, 7, 11, 13, 17, 19, 23.... are the prime numbers. Note: Zero (0) and 1 are not considered as prime numbers. Two (2) is the only one even prime number because all the numbers can be divided by 2.Let's see the prime number program in C. In this c program, we will take an input from the user and check whether the number is prime or not. ExampleCompile and RunOutput: Enter the number to check prime:56 Number is not prime Enter the number to check prime:23 Number is prime Next TopicPalindrome program in C |
