if a function is defined as
what does it mean? A function that accepts memory address should be defined as first(int * value) and when calling the function it should be called as first(&var_name) But what does the above function definition mean?Code:int first(int & value) {}
Thanks
value is passed as a reference, from what I understand it's basically the same thing as a pointer argument, except that when you use pass by reference, you don't need to dereference inside the function definition.

Thank you very much for that helpful post
however I still don't exactly understand the difference between declaring func(int &var) and func(int *var)
Is it that declaring *var passes address of function by value and &var doesn't?
Or did I understand it wrongly?
What book are you using to learn C++. You should eventually reach the section where they explain C++ references to you.
Look up a C++ Reference and learn How To Ask Questions The Smart WayOriginally Posted by Bjarne Stroustrup (2000-10-14)
You can't learn the language asking questions piecemeal. Get a decent book and work your way through it.
ok Thank you very much
PS: How do I edit a previous post here (I mean an old one and not just the latest one) or how do I mark my thread as solved?

You can't edit old posts after a certain time interval. This is to stop newbies editing out their entire source code after they get their answers.
You can't mark threads as solved. There simply isn't such a feature, for good or for bad.
I just wanted to know if there is a way to edit the title of the thread to say "solved"
There isn't, but you can ask a moderator to do it for you.
Alternatively, if you really think such a feature is warranted, you can always suggest it to be added to the board. Just post in general discussion or PM webmaster.
That's true, but I am sure the webmasters must have had their reasons for not implementing it yet
You never know. Webmaster might just not have thought about it and it hasn't been requested by any board members. It never hurts to ask.
You really think so?
If so I request the moderators to suggest the webmaster that a feature to allow the starter to mark the thread as solved be added
I am sure the moderators probably read all the posts so this should not go unnoticed
By the way, you're wouldn't happen to be a moderator would you?
Just checking
You don't need to contact moderators to do that. You'd contact webmaster.
Nope, not a moderator
you know what, I think a moderator will probably lock this thread anyway because it is going way off topic
So this will be my last post here
By the way, thanks to everyone for your help
