C++程序：基于医院白细胞样本计算平均数量与误差，助力新抗生素疗效分析

```cpp #include <iostream> #include <iomanip> #include <vector> #include <algorithm> #include <cmath> int main() { int n; std::cin >> n; std::vector<double> samples(n); // 读取所有样本值 for (int i = 0; i < n; ++i) { std::cin >> samples[i]; } // 对样本值进行排序 std::sort(samples.begin(), samples.end()); double sum = 0; // 计算有效样本的总和 for (int i = 1; i < n - 1; ++i) { sum += samples[i]; } // 计算平均白细胞数量 double average = sum / (n - 2); double error = 0; // 计算误差 for (int i = 1; i < n - 1; ++i) { double diff = std::abs(samples[i] - average); if (diff > error) { error = diff; } } // 输出结果，保留两位小数 std::cout << std::fixed << std::setprecision(2) << average << " " << error << std::endl; return 0; } ``` ######[AI问答 | 306点数解答 | 2025-11-24 14:44:22]
