Use a class as a variable type in another class / include file.

Hello. I am quite new to the c++ language, and am still trying to
learn it. I recently discovered how using include files would allow me
to split up my code into smaller segments, instead of having class
definitions etc. in one big file (yay, major discovery...).

My problem is this:

When I define a class in one include file, and then try to instantiate
it in another, I get compile-time errors saying the type is invalid.
If i move the class definition of the class which instantiates the
other class into the main .cpp-file i get no errors.

How to solve this problem? I would like to have each class in seperate
include files, but still be able to instantiate them inside each
other.

I am using Microsoft Visual C++ 6.0 on Windows XP.

strtok and atoi are both evil functions. atoi exhibits undefined behavior if
you give it data outside the range. strtok is a piece of crap that has no
business ever getting standardized. You do know that it writes over
the input string (in addition to storing internal state).

I'm not clear why you just didn't use a strea and formatted I/O here. It
would have been much easier.

Thank you for your suggestions to improve my code.

I'm afraid I don't know what 'strea and formatted I/O' is. I'd
appreciate if you'd point me to a link describing it, or perhaps
descibe it yourself... :)

Well, I wrote my first PHP class today. Yeah! But to get it to work, in each function within the class I have to repeat the database connection lines, and that just seems redundant; there has to be a better way that I'm just not bright enough to think of. Any suggestions? (It's the first 3 lines of each of the two functions below. When I have it fully written, there will be about 10 similar functions, each repeating those three lines.)

Hi, I don't get the difference between a struct and a class ! ok, I know that a struct is a value type, the other a reference type, I understand the technical differences between both, but conceptually speaking : when do I define something as 'struct' and when as 'class' ? for example : if I want to represent a 'Time' thing, containing : - data members : hours, mins, secs

Below is a class that is suppose to represent a segment of memory or a contents of a binary image (e.g. ELF executable). I have started to read Modern C++ Design and thought the best way to ensure I was understanding the chapter on policy classes was to attempt to apply them to my project. I understand the general concept of policies but I lack the knowledge and wisdom of how to identify them in an existing project. So I figured to get an...

Using VS 2003, I am trying to take a class that I created to create new variable types to handle nulls and track changes to standard variable types. This is for use with database variables. This tells me if a variable has changed, give me the original and current value, and whether the current value and original value is/was null or not. This one works fine but is recreating the same methods over and over for each variable type. ...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
