C++ 实现：统计并求和数列中大于 x 且小于 y 的整数

```cpp #include <iostream> using namespace std; int main() { int n, x, y; cin >> n >> x >> y; int sum = 0; for (int i = 0; i < n; i++) { int num; cin >> num; if (num > x && num < y) { sum += num; } } cout << sum << endl; return 0; } ``` ######[AI问答 | 101点数解答 | 2026-01-18 19:03:32]
