以下代码是我的C类幻灯片的一部分. IntelliSence给了我错误,我不知道为什么.不知道为什么它不喜欢构造函数和析构函数.有人可以帮忙吗？
class Vehicle {
friend void guest();
private:
string make;
string model;
int year;
public:
void Vehicle();
void Vehicle(string,string,int);
void ~Vehicle();
string getMake();
}
void guest() {
cout << make;
}
1) IntelliSense: member function with the same name as its class must be a constructor
2) IntelliSense: member function with the same name as its class must be a constructor
3) IntelliSense: return type may not be specified on a destructor
解决方法
构造函数和析构函数没有返回类型！应该：
Vehicle(); Vehicle(string,int); ~Vehicle();
您需要将参数传递给您的函数：
void guest(const Vehicle &v)
{
cout << v.make; //friend allows you to access 'make' directly
}
当然,您必须相应地更改好友声明
别忘了;在课程结束时
编辑
有效的完整代码：
class Vehicle {
friend void guest(const Vehicle &v);
private:
string make;
string model;
int year;
public:
Vehicle() {}
Vehicle(string make,string model,int year) : make(make),model(model),year(year) {}
~Vehicle() {}
string getMake() const {return make;}
};
void guest(const Vehicle &v) {
cout << v.make;
}
int main()
{
guest(Vehicle("foo","bar",10));
return 0;
}
