Get and Set Methods in C++ OOP

Question

In my computer science class I have an enum value in a header file and I'm having troubles with the get and set functions. I'm quite new to C++. This is part of my header file:

enum class SchoolType {
    Elementary = 1,
    Secondary = 2
};

class School : public Institution
{
    public:
        // There are a couple more values here

    SchoolType GetSchoolType();
    void SetSchoolType(SchoolType typeSchool);
};

And this is part of my .cpp file:

SchoolType GetTypeSchool()
{
    return this->_typeSchool;
}
void SetTypeSchool(SchoolType typeSchool)
{

}

But 'this' brings up an error and says that 'this' may only be used inside a nonstatic member function. How can I get that function to work? My computers teacher told me that that is how I should code the get function but I still don't understand, is there something that I'm doing wrong in the header?

Answer 1

For the .cpp file, you should have:

SchoolType School::GetSchoolType() {
    return this->_typeSchool;
}
void School::SetSchoolType(SchoolType typeSchool) {
    // Insert code here...
}

Basically, in C++ you need to specify what class the function is part of (in this case, School) when defining the member functions, or else the compiler doesn't see it as being part of any class. You also need to keep your method names consistent (GetSchoolType vs GetTypeSchool).
