#C++的输出问题，有输入但是却不知道怎么输出。

Question

运行代码之后有输入但没有输出，有没有专家能够教一下？

#define _CRT_SECURE_NO_WARINGS
#include <iostream>
#include <algorithm>
using namespace std;
const int MAX_N = 100;
int n, a[MAX_N];
void solve()
{
    int ans = 0;

    for (int i = 0; i < n; i++) {
        for (int j = i + 1; j < n; j++) {
            for (int k = j + 1; k < n; k++) {
                int len = a[i] + a[j] + a[k];
                int ma = max(a[i], max(a[j], a[k]));
                int rest = len - ma;//其余两棍之和

                if (ma < rest) {if (ma < rest) {
                    ans = max(ans, len);
                }
            }
        }
    }
printf("%d\n"，&ans);
}
    int main()
    {
        scanf_s("%d", &n);
        for (int i = 0; i < n; i++)
        {
            scanf_s("%d", &a[i]);
        }
     solve();
}

你都没输出的操作
