Question

#include <stdio.h>
#include <math.h>

int main() {
int a, b, sum = 0;
scanf("%d", &a);
while(a != 0) {
b = a % 10;
sum += pow(b,3);
a = a/10;
}
printf("%d", sum);

Answer 1

I wrote it exactly as it is here and it came out normal. You may be missing the return 0; the last one.

Answer 2

Lo escribí exacto como está aquí y me salió normal. Puede ser que te falte el return 0; al último.

Answer 3

You are welcome.
