输入矩阵元素输出完整矩阵的C++代码实现

```cpp #include <iostream> using namespace std; const int MAXN = 10; int matrix[MAXN][MAXN]; int main() { int n, m; // 输入矩阵的行数和列数 cin >> n >> m; // 输入矩阵的元素 for (int i = 0; i < n; i++) { for (int j = 0; j < m; j++) { cin >> matrix[i][j]; } } // 输出矩阵 for (int i = 0; i < n; i++) { for (int j = 0; j < m; j++) { if (j > 0) { cout << " "; } cout << matrix[i][j]; } cout << endl; } return 0; } ``` ######[AI问答 | 227点数解答 | 2026-03-07 20:40:54]
