To check whether the given Number is Armstrong Number or Not by using for loop

 Program:

#include<stdio.h>

#include<conio.h>

void main()

{

    int n, sum=0, m, r;

    clrscr();

    printf("Enter any Number : ");

    scanf("%d", &n);

    m=n;

    while(m>0)

    {

        r=m%10;

        sum=sum+(r*r*r);

        m=m/10;       

    }

    if(n==sum)

        printf("Given Number is Armstrong Number ");

    else

        printf("Given Number is Not Armstrong Number ");
