hey all, let's say i'm coding, coding, coding, making good progress and all, and then realize a crucial data is, and rightly so, private in another class. should i make it public, use a get function (won't that double overhead), or move around two hours worth of work. i've never had a set back this big before, what should i do?
I'd just make it public, but that's cuz I'm lazy!
IMHO, it really depends on the situation and what's going on. In some cases you might want to use inheritence. Others you would use a friend function. Others you would use composition. Etc... Etc..
Give us a little snippet or some code to help us give you more advice.
MSDN has documentation on the "friend" keyword. This is what I suggest that you use. Check it out, tell me what you think and if it applies to you. "The friend keyword allows a function or class to gain access to the private and protected members of a class..."

Sorry if it isn't much help.
On a very general basis I would say to use a public access method(getXXX) to access privat member variables.
I'm going to agree with Barjor. Go through a method to get the value. It's good practice to do and it'll help keep your code modular.
I do agree also, I was just providing some options. I would not personally use the friend keyword myself. :)
:D
wow guys thanks a lot. this is the best response i've had in a while. i tried the get function and it seems to be working fine. i think next time i'll use a freind just for the practice. again thanks a lot.
You're lucky, I'd imagine some people still have unanswered questions after posting on this board. The primary reason for me coming here, my one question, was never answered. The most of a response I got was somebody telling me it was possible. So if you know the answer to something that you see somebody is asking, don't hesitate to write it. Do not think that it is easy and somebody else will post the answer so you do not have to. It wouldn't be a messageboard if no one tried to respond. This messageboard is like its own minicommunity and everyone is part of it. Each person is a vital organ in this community, and each person plays a part. Granted, more ask than answer, but even if a selfish person answered every 1 in a 1,000 questions asked it would be a relief of stress off of another programmer's back. This practice (programming) should not be competitive in the least. Progammers should feel like they are part of their own community where each individual helps another out, and knowing that this help is for the greater good of all programmers. That one programmer helping another may become a contageous epidemic, influencing a programmer to repeat this action and to bear no resentment toward the programming world. If this were so then the technological world would progress a little more rapidly, and this world may smile a bit more. But, alas, it shall not. And I shall try and dream no longer.
Sorry, I did not mean to go off onto such a tangent. I was merely stating my feelings, but clearly I have gone too far.
