Parameter Specification in Python, Java, C++, C#: Optional Values, Default Values, and Overloading

This video deals with subprograms, meaning functions, procedures, and to a certain extent methods. It defines the basic concepts of formal and actual parameters, and defines subprogram calls, definitions, and headers. It also gives examples in various languages (Java, Python, C++, C#) of some interesting things you can do with parameters, such as define default values, or have a formal parameter represent a variable number of actual parameters.
