去掉注释后的C++完全数查找代码

```cpp #include <iostream> bool isPerfect(int num) { int sum = 0; for (int i = 1; i < num; i++) { if (num % i == 0) { sum += i; } } return sum == num; } int main() { int n; std::cout << "请输入一个正整数 n: "; std::cin >> n; std::cout << "2 到 " << n << " 之间的完全数有: "; for (int i = 2; i <= n; i++) { if (isPerfect(i)) { std::cout << i << " "; } } std::cout << std::endl; return 0; } ``` ######[AI问答 | 207点数解答 | 2026-03-14 20:06:22]
