C语言大佬救救我啊，指针问题

Question

怎么用指针啊？不能用[……]. ta定义了一个score[3][3],要求输入n，输出score[n][0~3],调用函数search(score,n)，必须要用指针，不能用到[……]

#include<stdio.h>

int main() {
    
    // 怎么用指针啊？不能用[……]. ta定义了一个score[3][3],要求输入n，输出score[n][0~3],调用函数search(score,n)，必须要用指针，不能用到[……]
    int score[3][3] = { {91, 92, 93},
                        {81, 82, 83},
                        {71, 72, 73}};
    int n;
    
    printf("Please enter n (0 ~ 2): ");
    scanf("%d", &n);
    
    if (0 <= n && n < 3) {
        int (*p)[3] = score + n;
        int *q = *p;
        
        for (int * q = *p; q < *p + 3; ++q) {
            printf("%d ", *q);
        }
    }
    else {
        printf("%d is out of range 0 ~ 2)!", n);
    }
    
    return 0;
}




// Output:
Please enter n: 0
91 92 93 

Please enter n: 1
81 82 83 

Please enter n: 2
71 72 73 

Please enter n (0 ~ 2): 3
3 is out of range 0 ~ 2)!
