    for ( j = 1 ; j <= 4 ; j ++ )
    {
        cin >> stu [10][4] ;
    }
}
for ( i = 1 ; i <= 10 ; i ++ )
{
    for ( j = 1 ; j <= 4 ; j ++ )

Answer 1

#include <iostream>
using namespace std;
int main(){


int stu [10][4] ;
int i, j ;
for ( i = 0 ; i < 10 ; i ++ )
{
    cout << "请输入"<< "第" << i+1 << "个学生的四门成绩: " ;
    for ( j = 0 ; j < 4 ; j ++ )
    {
        cin >> stu [i][j] ;
    }
}
for ( i = 0 ; i < 10 ; i ++ )
{
    for ( j = 0 ; j < 4 ; j ++ )
    {
    cout << stu [i][j] <<" ";
    }
    cout<<endl;
}
