打印出来几位数的水仙花数

如果输入3就打印出所有三位数的水仙花数

#include <stdio.h>
int main() {
	int n;
	scanf("%d", &n);
	int first = 1;
	int i = 1;
	while (i < n) {
		first *= 10;
		i++;
		//TODO
	}
	/*printf("first=%d\n",first);*/
	i = first;
	while (i < first * 10) {
		int t = i;
		int sum = 0;
		do {
			int d = t % 10;
			t /= 10;
			int p = d;
			int j = 1;
			while (j < n) {
				p *= d;
				j++;
				//TODO
			}
			sum += p;
		} while (t > 0);
		if (sum == i) {
			printf("%d\n", i);
			//TODO
		}
		i++;
	}
	return 0;
}
