C++实现计算指定区间内所有整数的因数之和

```cpp #include <iostream> using namespace std; // 计算一个数的因数之和 int factorSum(int num) { int sum = 0; for (int i = 1; i <= num; i++) { if (num % i == 0) { sum += i; } } return sum; } int main() { int m, n; cin >> m >> n; int totalSum = 0; // 遍历从 m 到 n 的所有整数 for (int i = m; i <= n; i++) { totalSum += factorSum(i); } cout << totalSum << endl; return 0; } ``` ######[AI问答 | 192点数解答 | 2026-04-25 19:51:38]
