Are class properties in C++?
Author
I''m currently working on a demo for a game in Visual Basic. Yayaya, I know, but it''s mostly for those who don''t know C/C++ too wekk yet (such as myself). However, I plan on "translating" it into C++ once I get a working algo and design.
I was wondering if C++ had anything like the Property Let, Property Get, and Property Set methods in Visual Basic. i.e.
Public Property Let TheProperty(WhatToSetTo as Whatever)
ClassPropery = WhatToSetTo
End Property
Or if C++ does it using functions anyways. i.e.
Public:
int SetWhatever(ToWhatever)
{
Whatever = ToWhatever;
Return Something;
}
I''m currently using functions to set the private data of my objects, but if C++ has properties, I will change these functions to them. What would you recommend?
Hope I made my question clear enough. I appreciate any advice, and thank you for your time.
You are correct in your assessment of the situation, in so much as it is usual to provide public getters and setters and make the underlying variable private ...
If you are using Micro$oft VC++ then you could either provide a COM wrapper to your generic C++, or write the DLL''s as COM. Either way COM provides you with Get and Set properties.
When you port your code to C++ be liberal with your use of const, it is a much underused thing ...

class Simple{public: Simple(); ~Simple(); const long get_Value() const; void set_Value(const long value);private: long m_Value;}
MSVC6 supports properties. More about it here:

Borland C++ Builder supports them too.

If you ever get my reply, I''d like to say thanks. Other than that, I have two even simpler questions: why won''t tabs or 5 spaces work on the forums to indent? Heh. I can''t stand it when I can''t indent paragraphs anymore. I must write too much. And the other: how do you get that lil code box to show up, or is it done using HTML or such? Thanks again.

i am guessing that spaces and tabs are ignored because the message board program turns the posts into HTML (which ignores whitespace after the first character of it)...
to put the white box put your stuff between [!source] and [!/source] (but without the !, i just put them to keep the thing from parsing them)... using [!code] and [!/code] will format your stuff without the white box (kinda like the tag in HTML).
you can also use [!i],[!/i],[!b],[!/b] for bold and italic.
for a hyperlink just use a HTML tag...

If you don''t want to bind it to one particular platform just overload operator= and a conversion operator and you have the same functionality

Uhh...no.

Uhh…no.
uhh…yes…
if you have those then it''s exactly like having set and get functions.

No. With overloading =, you are doing it for the entire class. You use gettor and settor methods to get/set individual properties of the class.
