有那个大神能帮我看看我的鞍点有什么问题吗

Question

#include using namespace std; int main() { int a[100][100], m, n, i, j,row=0,rowel=0; int max[6] = {}, min[6] = {}; cin >> m >> n; for (i = 0; i <= m; i++) for (j = 0; j <= n; j++) cin >> a[i][j]; for (i = 0; i <= m; i++) { for (j = 0; j <= n; j++) if (a[i][j] > max[i]) max[i] = a[i][j]; row = i; } for (i = 0; i <= m; i++) { for (j = 0; j <= n; j++) if (a[j][i] < min[i]) min[i] = a[j][i]; rowel = j; } for (i = 0; i <= m; i++) for (j = 0; j <= n; j++) { if (a[i][j] == max[i] && a[j][i] == min[i]) cout << a[i][j] << endl; else cout << "null" << endl; } return 0; }

#include<iostream>
#include<algorithm>
using namespace std;
int main()
{
    int m,n,i=0,j=0,k=0,row=0,colum=0,max=0,min=0,t=0,f=0;
    cin>>n>>m;
    int a[n][m];
    for(i=0;i<n;i++)
    {
        for(j=0;j<m;j++)
        {
            cin>>a[i][j];
        }
    }
    for(i=0;i<n;i++)
    {
        max=a[i][0];
        int b[m];
        for(j=0;j<m;j++)//寻找每一行的最大值
        {
            b[m]=a[i][j];
            if(a[i][j]>max)
            {
                max=a[i][j];
                colum=j;
                row=i;
            }
        }
        sort(b,b+m);
        if(b[m-1]==b[m-2]) {continue;}//排除最大值为众数的情况
        else
        {
            for(k=0;k<n;k++)//判断是否为列的最小值
            {
                min=a[row][colum];
                if(k!=row&&a[k][colum]<=min)
                {
                    t=0;
                    break;
                }
                else {t=1;}
            }
            if(t==1) {f=1;cout<<a[row][colum]<<endl;}
        }
    }
    if(t==0&&f==0) cout<<"null"<<endl;
    return 0;
}

你的循环有点乱，if语句有时后面没加括号但是跟了两个执行语句
