armstrong number code code example
Example 1: armstrong number
sum of cubes of the digits
Example 2: armstrong number in c
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int cube(int a)
{
int c;
c = a*a*a;
return c;
}
int armnum(int *a)
{

while (x != 0) {
x /= 10;
n++;
}
x = *a;
while (x != 0) {
rem = x % 10;
r += cube(rem);
x /= 10;
}
if(r == *a){
return 1;
}
}
int main()
{
int a, y;
scanf("%d", &a);
y = armnum(&a);
if(y == 1){
printf("It is an Armstrong number.");
}
else{
printf("It is not an Armstrong number.");
}
}
