I suggest you write some @#$# lprograms and you'll experience that you can't without.
Pointer are very important especialy with classes and in windows programming.
but what the point of the pinters...?
can any one give me an EX?
Imagine if you will, you have a class in your game that is very big. Let's say it takes up a few megs. Whenever you want to pass that class to a function to have something performed on it , if you DO NOT use pointers a copy of the class is made and then passed to the function. This is very slow and horrible for speed. Instead you could pass a pointer TO the class. A pointer is just something that points to a memory address so it is usually 4 Bytes. This way only the address is passed and you can directly modify the class.
"...the results are undefined, and we all know what "undefined" means: it means it works during development, it works during testing, and it blows up in your most important customers' faces." --Scott Meyers
polymorphism is achieved through a combination of inheritance and pointers.
the topic of pointers is very important in c/c++ programming, i used to wish that pointers have not existed back in the days of my c class i feared and hated it.
just learn it at a comfortable pace and u'll soon be using pointers as would terminate a statement with a ;.
Thax
i know how to use them
but i dont understand Y
so i'll learn more
thanx
