Gang of Four - Design Patterns - are those pattern samples coded in outdated way?

So to clarify my question... each pattern in infamous GoF book - Design Patterns Elements of Reusable Object-Oriented Software - has its code samples in C++.

Are those up to date? Or does nowadays code in C++ look very different?

I'm asking that, because when I posted my code with my last question, lots of C++ devs told me that I should get rid of pointers, pointers that are widely used there...
