Check Number is Prime or not using For loop


Write a C Program to Check whether a Number is Prime or not using For loop Here’s simple C Program to Check whether a Number is Prime or not using For loop in C Programming Language.


Numbers in C


Normally, when we work with Numbers, we use primitive data types such as int, short, long, float and double, etc. The number data types, their possible values and number ranges have been explained while discussing C Data Types.


Here is source code of the C Program to Check whether a Number is Prime or not using For loop. The C program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/*  C Program to Check whether a Number is Prime or not using For loop  */

#include<stdio.h>

int main()
{
    int i, prime = 1, n;
    printf("\nENTER ANY NUMBER :: ");
    scanf("%d", &n);

    for(i=2; i<n; i++)
    {
        if(n%i == 0)
        {
            prime = 0;
            break;
        }
    }

    if(prime)
        printf("\nTHE NUMBER [ %d ] IS A PRIME NUMBER.\n", n);
    else
        printf("\nTHE NUMBER [ %d ] IS NOT A PRIME NUMBER.\n", n);

    return 0;
}

OUTPUT : :


/*  C Program to Check whether a Number is Prime or not using For loop  */

ENTER ANY NUMBER :: 12345

THE NUMBER [ 12345 ] IS NOT A PRIME NUMBER.

Process returned 0

Above is the source code for C Program to Check whether a Number is Prime or not using For loop which is successfully compiled and run on Windows System.The Output of the program is shown above .
