指针，动态数组和函数问题

Question

帮忙看看有什么错误
输入M个班级（每个班级N个学生） 学生的计算机文化基础课程成锁，请你设计一个西数来编程找出这些学生中成锁最商的同学 （假定最商分只有一名同学），返回最高成绩、该同学是第几个班级的第几个学生（斑级和学生编号均从1开始）。

Answer 1

动态数组和指针：

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int x, y, highestScore, highestClass, highestStudent;
    int i, j;
    int** score = 0;
    scanf("%d %d", &x, &y);
    score = (int**)malloc(sizeof(int*) * x);
    
    for (i = 0; i < x; i++) {
        score[i] = (int*)malloc(sizeof(int) * y);
        for (j = 0; j < y; j++) {
            scanf("%d", &score[i][j]);
            if (i == 0 && j == 0) {
                highestScore = score[i][j];
                highestClass = i + 1;
                highestStudent = j + 1;
            }
            else
            {
                if (score[i][j] > highestScore)
                {
                    highestScore = score[i][j];
                    highestClass = i + 1;
                    highestStudent = j + 1;
                }
            }
        }
    }
    printf("%d ", highestScore);
    printf("%d %d", highestClass, highestStudent);
    //释放内层
    for (i = 0; i < x; i++)
        free(score[i]);
    free(score);
    return 0;
}
