You mean the code looks strange? Are there better alternatives to the above code?
I do feel that the question is a little odd though.
Lets say I have a parent class called:
Then there is a derived class called Toyota, which has a method returning a pointer to the parent class and a vector of pointers...

I created a templated class which searches for a path between 2 points in a graph. The template parameter takes in a class representing the graph.
template <class graph_type>

I came across a piece of code which is a RTTI class. (run time type information). The class is called "RTTI".
There are a few defines below the class declaration and one of them is this:

I am using visual studio 2008 professional and during compilation, the errors and warnings are all displayed together, making it hard to identify the error messages.
How do I remove the compile...

yes, the data is in memory.
Well i guess i'll use structures instead. Thanks all for the advice :)

I would like to save in-game data like player's health, ammo power etc into memory.
The reason is that the game is split into states with each level represented by a state. When a level loads,...

I have tried using this:
BaseClass* bc = dynamic_cast<DerivedClass*>ReturnClassType();
But there was still an error. Is the dynamic cast done correctly?

I have a base class pointer which is assigned a derived class. Can this pointer call methods in the derived class which are not declared in the base class?

No wonder the values are so strange.
Is declaring an extern float in a .h file and including the header file in the 2 classes the correct method to use that global variable?

I have created a program wide global variable in a .h file called globals.h
Inside the .h file, the global variable is declared as:
extern float g_fFrameTime;
2 other classes use this global...

Is it to create a new window sized bitmap for copying and clearing for each frame?
Is there an alternative method to this as the window already has 2 bitmaps, one of which is a 2D terrain which is...

There is a zip file which contains a folder inside it. The folder itself contains a few files. I would need to know how to extract the folder (with its contents) from inside a zip file.

I created a bitmap object and used it to draw a 2D terrain programatically. Then I also added a picturebox control to display an image near the terrain.
However, the picturebox control is...

i've printed out the exception message and it says that the zip file must have at least 1 entry.
java.util.zip.ZipException: ZIP file must have at least one entry
April 3rd, 2008, 11:29 AM
Yep, I guess the problem is that the control is not actually added to the form. Thanks!~ :)

I have a method which performs zipping. I took the zipping code found on the net and modified it to make sure that folders can be zipped as well.
When using the code to zip a folder, it always...
