c++ - 类构造函数错误，类 "classname"没有成员 "classname"

Question

#ifndef RESERVATIONS_H_INCLUDED
#define RESERVATIONS_H_INCLUDED
#include <vector>
#include <string.c>

class Reservations
{
public:
    Reservations::Reservations { }
    Reservations(string FullName, int PhoneNum);
    string getname() { return FullName; }
    int getnumber() { return PhoneNum; }
private:
    string FullName;
    int PhoneNum;
}

#endif // RESERVATIONS_H_INCLUDED

Reservations::Reservations(string FullName, int PhoneNum) //error on this line
{
    FullName = FullName;
    PhoneNum = PhoneNum;
}

我在标题中得到了错误，我不知道为什么它假设我希望它有一个属于它自己的类的成员......

Answer 1

你包含了错误的头文件

改变

#include <string.c>

到

#include <string>

也可以使用带有完整命名空间标准的字符串。

下面的代码应该通过小的修复来编译:

class Reservations
{
public:
    Reservations() : PhoneNum(0) {}
    Reservations(std::string FullName, int PhoneNum);
    std::string getname() { return FullName; }
    int getnumber() { return PhoneNum; }
private:
    std::string FullName;
    int PhoneNum;
};

Reservations::Reservations(std::string FullName, int PhoneNum) 
{
   this->FullName = FullName;
   this->PhoneNum = PhoneNum;
}

// Better use member initializers list
Reservations::Reservations(std::string FullName, int PhoneNum) 
: FullName(FullName),
  PhoneNum(PhoneNum)
{
}
