三菱结构体编辑的语句怎么修改

以下是四个例子，演示了如何编辑Mitsubishi结构体。

1. 修改结构体成员的值：
```cpp
struct Mitsubishi {
int year;
string model;
float price;
};

Mitsubishi car;
car.year = 2022;
car.model = "Lancer";
car.price = 25000.0;
```

2. 使用新的值初始化结构体的另一个实例：
```cpp
struct Mitsubishi {
int year;
string model;
float price;
};

Mitsubishi car1;
car1.year = 2022;
car1.model = "Lancer";
car1.price = 25000.0;

// 使用car1的值初始化car2
Mitsubishi car2 = car1;
```

3. 通过指针修改结构体成员的值：
```cpp
struct Mitsubishi {
int year;
string model;
float price;
};

Mitsubishi car;
Mitsubishi* carPtr = &car;

(*carPtr).year = 2022;
(*carPtr).model = "Lancer";
(*carPtr).price = 25000.0;
```
或者使用成员访问操作符 `->` 编辑结构体成员的值：
```cpp
struct Mitsubishi {
int year;
string model;
float price;
};

Mitsubishi car;
Mitsubishi* carPtr = &car;

carPtr->year = 2022;
carPtr->model = "Lancer";
carPtr->price = 25000.0;
```

4. 通过函数修改结构体成员的值：
```cpp
struct Mitsubishi {
int year;
string model;
float price;
};

void updateCar(Mitsubishi& car, int newYear, string newModel, float newPrice) {
car.year = newYear;
car.model = newModel;
car.price = newPrice;
}

Mitsubishi car;
updateCar(car, 2022, "Lancer", 25000.0);
```
