多维数组指针用法，求平均值

Question

求二维数组score[3][4]的平均值
用多维数组指针用法

Answer 1

float fun1(float score[][4], int n){
    int i, j;
    float sum = 0.0;
    for (i = 0; i < n; i++)
    {
        for (j = 0; j < 4; j ++)
        {
            sum += score[i][j];
        }
    }

    return sum;
}

float fun2(float* score, int n){
    int i;
    float sum = 0.0;
    for (i = 0; i < n; i++)
    {
        sum += score[i];
    }

    return sum;
}
