贺老师教学链接  C语言及程序设计提高 本课讲解

用多维数组名作函数参数

#include <stdio.h>    
int max_value(int array[][4]);
int main( )
{
    int a[3][4]= {{11,32,45,67},{22,44,66,88},{15,72,43,37}};
    printf("max value is %d\n", max_value(a));
    return 0;
}

{
    int i,j,max;
    max=array[0][0];
    for( i=0; i<3; i++)
        for(j=0; j<4; j++)
            if(array[i][j]>max)
                max=array[i][j];
    return max;
}
