How many member functions within Thing class?

jack223 · #1 08-Nov-2005, 08:38

CPP / C++ / C Code:

class Thing {

public:
     int Item;
     Thing (int Value);
     Thing (int Value1, int Value2);
     int GetValue1 () const;
     int GetValue2 () const;

private:
     int DataItem1;
     int DataItem2;
     void SetValue1 (int Value);
     void SetValue2 (int Value);
}

How many member functions does class Thing have?

-Thing (int Value)
-int GetValue1()
-int GetValue2()
-void SetValue1 (int Value)
-void SetValue2 (int Value)

-int DataItem1....this is data member...is it part of member function?

are there more member functions that I missed??

Constructors are also member functions.

Six.

No. DataItem1 is not a member function. It is a member variable.
I hope you know the difference between a function and a variable.

Yes. This:
Thing (int Value1, int Value2);

Hence the total member functions are:

Quote:

-Thing (int Value)
-int GetValue1()
-int GetValue2()
-void SetValue1 (int Value)
-void SetValue2 (int Value)
-Thing (int Value1, int Value2);

and the total member variables are:

Quote:

int Item;
int DataItem1;
int DataItem2;

so in this case, constructors are: Thing (int Value), and Thing (int Vlaue1, int Value2)...is that right?

Yes.
Do you know the difference between them?
One constructor uses only one argument.
The other uses two arguments.
This is called overloading.
