My understanding of the term psudo-code is that it is part way between english 
and code.  Someeimes its almost code, but its not intended to compile or be 
correct syntax, it may even be written in terms of different programming 
languages.  But the term may be broader than I understand.  Anyway I get what 
you are asking.

I have only done a little C++, unfortuanatly my attempts to learn it got 
squeezed out.  But I will answer your question form what I know and if thats 
not enough I am sure someone who understands more C++ can give further hints.

The idea here is to create a class from which you will create objects that 
represent each CD.  Inside this class it will have fields for all the pieces 
of data mentioned above, as well as functions that initialise variables, 
change variable, and allow you to read variables.  Something like this

class CD{
	 char *artist;
	 char *album title;
	 char *year;
	 char *genre

	CD() {initialise CD}
	void changeGenre() {}
	char *getCDdetails() {}
}

You will also need some static program to manage the CD, create them, ahange 
them, search for them, print them out etc.

This may well be possible but isn't a basic C++ action.  If you are learing a 
language you would normally keep the data in something like a text file.  The 
program then load the info into memory for use, creating objects and acting 
on those objects as it proceddes.

I don't know anything about working with mysql from C++, perhaps someone else 
can answer this.

Hopefully i have helped a bit.  Ask more questions if it still not clear.
