大一新生啥也不会，help me，代码写不出来，没什么思路，有会的朋友，帮帮我

#include <math.h>
#include <stdio.h>
int main()
{
    int n;
    do
    {
        scanf("%d", &n);
    } while (n > 7 || n < 3);

    int N = 1;
    for (int i = 1; i < n; i++)
        N *= 10;

    for (int i = N; i < N * 10 - 1; i++)
    {
        int sum = 0, t, x = i;
        while (x)
        {
            t = x % 10;
            sum += pow(t,n);
            x /= 10;
        }
        if (i == sum)
            printf("%d\n", i);
    }

    return 0;
}
