C错误C2533,ctor：构造函数不允许返回类型

概述我有一个叫老师的课 class Teacher{private: int ID; string qualification; double salary; Date DOB; Date dateJoined;public: Teacher(); void setTeacher (int, string, double); str 我有一个叫老师的课

class Teacher{private:    int ID;    string qualification;    double salary;    Date dob;    Date dateJoined;public:    Teacher();    voID setTeacher (int,string,double);    string getQualification();    voID displayTeacher();}//This is my constructorTeacher::Teacher(){     ID = 0;     qualification =" " ;     salary=0.0;}

我收到错误C2533：’Teacher :: {ctor}’：构造函数不允许返回类型.
我哪里做错了？

解决方法 你没有在类定义后加一个分号.

这会让解析器感到困惑,现在认为你正在写这样的东西：

class {}     functionname(args) {} ^^^^^^^^     ^^^^^^^^^^^^return type   constructors defined     are functions,but in-place     they don't have  (oops)       return types!                 (oops)

现代GCC(比如4.9.2)对这个问题非常清楚：

class Teacher{    Teacher();}Teacher::Teacher(){}// main.cpp:3:1: error: new types may not be defined in a return type//  class Teacher//  ^// main.cpp:3:1: note: (perhaps a semicolon is missing after the deFinition of 'Teacher')// main.cpp:8:18: error: return type specification for constructor invalID//  Teacher::Teacher()//                  ^
