C经典 求二维数组的最大值与行，还有列

#include <stdio.h>

int main(int argc, const char * argv[])
{

    // 求二维数组最大值及下标
    int arr[5][3] = {
        {67,89,90},
        {80,90,80},
        {59,43,78},
        {99,68,98},
        {56,89,67}
    };
    //用数组得第一个元素当作最大值
    int max = arr[0][0];
    //行
    int row = -1;
    //列
    int col = -1;

    for (int i = 0; i < 5; i ++) {
        for (int j = 0; j < 3; j ++) {
            if(arr[i][j] > max){
                max = arr[i][j];
                row = i;
                col = j;
            }
        }
    }

    printf("最大值%d\n", max);
    printf("行%d\n", row + 1);
    printf("列%d\n", col + 1);

    printf("\n");
    return 0;
}
