我好像在报错的同时进入了C++的头文件库！！！在一天我写程序的时候，日常语法报错，可是在我查看报错的时候，突然点进了一个数据库，应该是头文件库，粘贴出来给大家看看： // C++ includes used for precompiling -- C++ --

然后下面就是一堆头文件，有C的，有C++的！！！非常全面，基本上都有了！！！！！！

哪位大神知道啥意思啊？？？源程序如下：

include

//必须要用万能头文件！！！！！！！！！

#define N 1000005
#define ll long long
using namespace std;

int a[N],n;
int m,max;

int maxf(int x, int y){return x>y?x:y;}

bool check(int x)
{
    int s = 0;
    for (int i = 1; i <= n; i++)
    {
        s+=maxf(a[i] - x,0);
        if (s >= m) return true;
    }
    return false;
}

int main()
{
    scanf("%d%lld", &n, &m);
    for (int i = 1; i <= n; i++)
    {
        scanf("%d", &a[i]);
        if (a[i] > max) 
        max = a[i];
    }
    int l=0,r=max;
    int ans = 0;
    while (l < r)
    {
        int mid = (l + r) / 2;
        if (check(mid))
        {
            l = mid + 1;
            ans = mid;
        }
        else r = mid;
    }
    printf("%d", ans);
}
//end
除了前三条报错以外，其他的报错点击进去，都能进入一个新世界！！！
大佬帮我看看咋回事？？？？
