用初值初始化二维数组并转置矩阵输出c++

可以使用以下代码来实现：

#include <iostream>

using namespace std;

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

    // 转置矩阵
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            transposed[j][i] = arr[i][j];
        }
    }

    // 输出原始矩阵
    cout << "Original Matrix: " << endl;
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            cout << arr[i][j] << " ";
        }
        cout << endl;
    }

    // 输出转置矩阵
    cout << "Transposed Matrix: " << endl;
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            cout << transposed[i][j] << " ";
        }
        cout << endl;
    }

    return 0;
}

输出结果为：

Original Matrix:
1 2 3
4 5 6
7 8 9
Transposed Matrix:
1 4 7
2 5 8
3 6 9
