如何在子类c ++的构造函数中设置基类的属性

Question

I have the following constructor in a class Student that is a subclass of a base class Person :

namespace Uni
{
    Uni::Student::Student(string majorCourse, int enrollNumber , string name, int age, bool isStudying)
        : Uni::Person::Person(std::__1::string name, int age, bool isStudying), majorCourse_(majorCourse), enrollNumber_(enrollNumber)    
    {
        cout << "[Temp] Student Default Constructor" << endl;
    }
    ...
}

I would like to set the attributes name_ , age_ and isStudying_ (which are attributes of the Person class) to the values of name , age , and isStudying , but I get an error on this statement:

Uni::Person::Person(std::__1::string name, int age, bool isStudying)

type name is not allowed

How can I fix this?

Answer 1

You should just be forwarding the arguments along to the base class, so lose the typenames

 Uni::Student::Student(string majorCourse, int enrollNumber , string name, int age, bool isStudying)
  : Uni::Person::Person(name, age, isStudying),
    majorCourse_(majorCourse),
    enrollNumber_(enrollNumber)
 { }
