C++实现矩阵左右镜像转换

```cpp #include <iostream> #include <vector> using namespace std; int main() { int n, m; cin >> n >> m; vector<vector<int>> matrix(n, vector<int>(m)); // 输入矩阵 for (int i = 0; i < n; i++) { for (int j = 0; j < m; j++) { cin >> matrix[i][j]; } } // 输出镜像矩阵 for (int i = 0; i < n; i++) { for (int j = m - 1; j >= 0; j--) { if (j != 0) { cout << matrix[i][j] << " "; } else { cout << matrix[i][j]; } } cout << endl; } return 0; } ``` ######[AI问答 | 225点数解答 | 2026-05-17 12:49:11]
