For greater programmer ease and safety, you might want to use virtual functions instead of function pointers. &nbsp;There is no need for funciton pointers in C++ (unless the project must interface with non-C++ code, like the OS.)<br />

I just want to echo wnat nietod has said. &nbsp;For those of you who want to write more object oriented code, when you come across a need for a function pointer -- step back and think about the problem and you'll see that a virtual function will fit the bill very nicely.<br />

OK, could you pls give me an example how do you write the AdrianBrown code (see on top of the page) by using virtual functions?<br />
thanks in advance<br />

Callback function

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
