Let’s try to understand why 371 is an Armstrong number.
371 = (3*3*3)+(7*7*7)+(1*1*1)
where:
(3*3*3)=27
(7*7*7)=343
(1*1*1)=1
So:
27+343+1=371
Let’s see the c program to check Armstrong Number in C.
#include<stdio.h>
int main()
{
int n,r,sum=0,temp;
printf(“enter the number=”);
scanf(“%d”,&n);
temp=n;
while(n>0)
{
r=n%10;
sum=sum+(r*r*r);
n=n/10;
}
if(temp==sum)
printf(“armstrong number “);
else
printf(“not armstrong number”);
return 0;
}
