        This article provides example of dynamic array implementation using C++ templates. It uses standard malloc/realloc memory allocation functions and simple "doubling size" resizing strategy. Our AeDynArray class interface resembles MFC standard CArray class

    This was not legal in C++03, because get_five() + 7 is not a constant expression. A C++03 compiler has no way of knowing if get_five() actually is constant at runtime. In theory, this function could affect a global variable, call other non-runtime constan...

    As in C++, you can use a private constructor to prevent programmers from creating instances of Singleton. To prohibit inheritance, declare your class sealed. (In C++ you can do this by making all constructors private.) Instead of a static object inside a ...
