Pointers to Class in C++ - Learn how to use pointers with classes in C++. This detailed tutorial covers syntax, examples, and best practices for effectively utilizing pointers in your C++ programs.
This flexibility can also be achieved by using classes with virtual functions I am grateful to Alex Hoffer and Thomas Carriero for their comments on a draft of this article.Related articles Lambda functions in C++11, a replacement for function pointers What are Pointers?Functors...
UNIX was written almost entirely in C and contains a built-in C compiler. Because of the C/UNDC link, fixture C programming was accomplished almost exclusively within the environment of UNIX. C holds a very special place in the classes of languages. Assembly language is a low-level type ...

I'll discuss this at length later in the article, because it's an area where the Standard bears little resemblance to real compilers. On some compilers, weird stuff happen even when converting between member function pointers of base and derived classes. When multiple inheritance is involved, ...
Since C does not have higher level features like interfaces, classes, templates, etc. C libraries must rely on the void* type. 68.12 Using pointers in logical expressions Pointers can automatically be converted to bool. Pointers that have the value null produce false and the others produce true...

This isn't so bad after all, when designing your own classes to work with smart pointers; it is easy to embed the reference count in the class itself, to get less memory footprint and better performance. To use a type T with intrusive_ptr, you need to define two functions: intrusive_...
