C++ Experts Forum The Standard Librarian: I/O and Function Objects: Containers of Pointers Matthew Austern Like most of the Standard C++ library, the standard container classes are parameterized by type: you can create an std::vector<int> to hold ob…

Theory In the Java the function pointers is implemented by the declaring an interface to represent strategy and a class that implements this interface for each concrete strategy. It is possible to define an object whose methods perform operations on…
