I was wondering if someone could give me a basic explination of what is a pointer in c++ and how it is used. I tried searching online, and I got a complicated answers (not for someone who has never heard of the consept before.) thanks very much....

From Teach Yourself C++ in 24 Hours (2nd Ed.) (ISBN: 0672315165) by Jesse Liberty:

quote:

p134: A pointer is a variable that holds a memory address.

A code snippet (from p137):

int howOld = 50; // Make a variable
int * pAge = 0; // Make a pointer
pAge = &howOld; // put howOld's address in pAge

Essentially, its how c++ gives you low-level access to RAM. Tred with care.

Hope this was helpful.
