Armstrong Numbers:

#include<stdio.h>
int main()
{
int i,j,k,l,m;
printf("give the number to find Armstrong (three digit)\n\n");
scanf("%d",&i);
j=i/100;
k=i%100;
l=k/10;
m=k%10;
j=j*j*j;
l=l*l*l;
m=m*m*m;
if(i==j+l+m)
{
printf("yes %d is an Armstrong number\n\n",i);
}
else
printf("not an Armstrong number\n\n");
}
