矩阵中特定位的c++写入

#include <iostream>
using namespace std;

const int ROWS = 3;
const int COLS = 3;

void writeValueInMatrix(int matrix[ROWS][COLS], int row, int col, int value) {
    matrix[row][col] = value;
}

int main() {
    int matrix[ROWS][COLS] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};

    // 输出原始矩阵
    cout << "原始矩阵：" << endl;
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            cout << matrix[i][j] << " ";
        }
        cout << endl;
    }

    // 写入特定位置的值
    int row = 1;
    int col = 2;
    int value = 10;
    writeValueInMatrix(matrix, row, col, value);

    // 输出修改后的矩阵
    cout << "修改后的矩阵：" << endl;
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            cout << matrix[i][j] << " ";
        }
        cout << endl;
    }

    return 0;
}

原始矩阵：
1 2 3 
4 5 6 
7 8 9 
修改后的矩阵：
1 2 3 
4 5 10 
7 8 9
