输入一个3×6的二维整数数组,输出其中最大值、最小值及其所在的行列下标。(用指针完成)

以下是代码实现：

#include <iostream>
using namespace std;

void findMaxMin(int arr[][6], int row, int col, int* maxVal, int* minVal, int* maxRow, int* maxCol, int* minRow, int* minCol) {
    *maxVal = arr[0][0];
    *minVal = arr[0][0];
    *maxRow = 0;
    *maxCol = 0;
    *minRow = 0;
    *minCol = 0;

    for (int i = 0; i < row; i++) {
        for (int j = 0; j < col; j++) {
            if (arr[i][j] > *maxVal) {
                *maxVal = arr[i][j];
                *maxRow = i;
                *maxCol = j;
            }
            if (arr[i][j] < *minVal) {
                *minVal = arr[i][j];
                *minRow = i;
                *minCol = j;
            }
        }
    }
}

int main() {
    int arr[3][6] = {{1,2,3,4,5,6},
                     {7,8,9,10,11,12},
                     {13,14,15,16,17,18}};

    int maxVal, minVal, maxRow, maxCol, minRow, minCol;
    findMaxMin(arr, 3, 6, &maxVal, &minVal, &maxRow, &maxCol, &minRow, &minCol);

    cout << "Max value: " << maxVal << " at (" << maxRow << ", " << maxCol << ")" << endl;
    cout << "Min value: " << minVal << " at (" << minRow << ", " << minCol << ")" << endl;

    return 0;
}

输出结果为：

Max value: 18 at (2, 5)
Min value: 1 at (0, 0)
