在printf处出现报错，是哪里出的问题呢？

Question

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

调用printf实际类型："int*"时需要整数时，非整数传递为_param_(2).
出现了这类报错时，因该如何修改代码呢？

Answer 1

printf("%d", &ans);
->
printf("%d", ans)
