编制程序判断用户输入的一个整型数是不是a.回文数，b.素数，c.回文素数,要求只能输出一个答案

#include <iostream>
using namespace std;

int isp(int n) {
    int i;
    for (i = 2; i <= n/2; i++) {
        if (n % i == 0)
            return 0;
    }
    return 1;
}

int ish(int n) {
    int m = n, t = 0;
    while (m) {
        t = t * 10 + m % 10;
        m /= 10;
    }
    return t == n;
}

int main() {
    int x;
    cout << "Input x:";
    cin >> x;
    if (isp(x) && ish(x))
        cout << "huiwen su shu";
    else if (isp(x))
        cout << "su shu";
    else if (ish(x))
        cout << "huiwen.";
    else
        cout << "no.";
    return 0;
}
