#include <stdio.h>

int main()
{
    float average(float(*p)[3], int n);
    
    int n = 2; //两行
    //printf("请输入行数：");
    //scanf("%d", &n);
    
    float arr[n][3];
    int i, j;
    printf("请输入%d行3列的数组：", n);
    for(i = 0; i < n; ++i){
        for(j = 0; j < 3; ++j)
            scanf("%f", &arr[i][j]);
    }
    
    printf("平均值为：%.2f\n", average(arr, n));
    return 0;
}

float average(float(*p)[3], int n)
{
    float sum = 0;
    int i, j;
    for (i = 0; i < n; i++)
    {
        for (j = 0; j < 3; j++)
            sum += p[i][j];
    }
    float mean = sum / (3 * n);
    return mean;
