New to C++. Question about constant pointers

I am trying to learn C++ via some web tutorials. I don\'t have a compiler available to me, otherwise I would try this out. I\'m not sure what is meant by a const pointer. Doe

Answer 1

You can't learn to drive a car just by reading books.

Get yourself a C++ compiler if you want to learn C++. g++ is free of charge, as well as Visual Studio 2008 Express Edition.

As for your question, a const pointer is a zone of memory that is ready only. Example: A class may provide read-only access to an internal buffer.

Note that you also have the const pointer that is also const, aka

const char * const p 

In that case, even the value of the pointer cannot be modified.
