使用include <iostream>时一定要加using namespace std
以下是该代码的简单 UML 类图:
```
+-------------------+
| Student |
+-------------------+
| - id: string |
| - name: string |
| - birthday: string|
| - gender: char |
| - height: float |
| - weight: float |
| - health_status: string |
| + count: int |
| + total_weight: float |
+-------------------+
| + Student(id: string, name: string, birthday: string, gender: char, height: float, weight: float) |
| + display_health_status(): void |
| + calculate_health_status(): void |
| + display_statistics(): void |
+-------------------+
```
在该类图中,`Student` 类包含了私有成员变量 `id`、`name`、`birthday`、`gender`、`height`、`weight` 和 `health_status`,以及静态公共成员变量 `count` 和 `total_weight`。该类还包含了公共成员函数 `Student()`、`display_health_status()`、`calculate_health_status()` 和 `display_statistics()`。
其中,`Student()` 构造函数用于初始化学生对象的各个属性,并计算该学生的身体状况。`display_health_status()` 函数用于输出该学生的身体状况。`calculate_health_status()` 函数用于计算该学生的身体状况。`display_statistics()` 函数用于输出所有学生的数量和平均体重。
此外,类图中还包含了 `+` 和 `-` 符号。`+` 表示该成员是公共的,可以被外部访问;`-` 表示该成员是私有的,只能被类内部的成员函数访问。
