仅使用`iostream`求解数组前三小元素

```cpp #include <iostream> #include <algorithm> int main() { int n; std::cin >> n; int arr[100]; for (int i = 0; i < n; ++i) { std::cin >> arr[i]; } // 排序数组 for (int i = 0; i < n - 1; ++i) { for (int j = 0; j < n - i - 1; ++j) { if (arr[j] > arr[j + 1]) { int temp = arr[j]; arr[j] = arr[j + 1]; temp = arr[j + 1]; } } } std::cout << arr[0] << " " << arr[1] << " " << arr[2] << std::endl; return 0; } ``` ######[AI问答 | 211点数解答 | 2026-07-11 15:44:23]
