Programme to Check whether a number is an Armstrong number

Here you will know how to Check  whether a number is an Armstrong number or not .
In this method we have used a while loop to check for an Armstrong number.I have also attatched the screenshots of the programme I have written and the generated output.


#include <stdio.h>
#include <stdlib.h>

int main()
{
   
    int num,r,result,sum=0,temp;
    printf("Enter a number");
    scanf("%d",&num);
    temp=num;
    while(temp!=0)
    {
        r=temp%10;     

        sum=sum+r*r*r;
        temp=temp/10;    

    }
    if(num==sum)

        printf("The entered number is an Armstrong number");

    else

        printf("The entered number is not an Armstrong number");

    return 0;

}


The screenshot is:

The generated output is:
