如何创建以下c++类的析构函数:class Manage { int total; int used; int unitPrice; vector<Vehicle *> parking; queue<Vehicle *> waiting; public: Manage(int, int); int vehicle_in(Vehicle); int vehicle_in(string, Color, int); bool in_park(Vehicle *); bool in_wait(Vehicle *); bool vehicle_out(Vehicle *); bool vehicle_out(int); int price(Vehicle *); bool change(string, Vehicle); vector<Vehicle> get_all(); int get_num(); };

以下是创建该C++类的析构函数的示例代码:
```
class Manage {
int total;
int used;
int unitPrice;
vector<Vehicle *> parking;
queue<Vehicle *> waiting;
public:
Manage(int, int);
~Manage(); // 析构函数
int vehicle_in(Vehicle);
int vehicle_in(string, Color, int);
bool in_park(Vehicle *);
bool in_wait(Vehicle *);
bool vehicle_out(Vehicle *);
bool vehicle_out(int);
int price(Vehicle *);
bool change(string, Vehicle);
vector<Vehicle> get_all();
int get_num();
};
Manage::Manage(int t, int u) {
// 构造函数的实现
total = t;
used = 0;
unitPrice = u;
}
Manage::~Manage() {
// 析构函数的实现,释放对象所占用的资源
for (int i = 0; i < parking.size(); i++) {
delete parking[i];
}
while (!waiting.empty()) {
delete waiting.front();
waiting.pop();
}
}
// 其他成员函数的实现
```
在该析构函数中,我们使用了for循环和while循环,分别遍历parking和waiting中的元素并释放它们所占用的内存。注意,由于parking中存储的是指向Vehicle对象的指针,因此需要使用delete操作符释放内存。
