Parameters : Pass by value, pass by reference

A Level Computer Science - Passing parameters to sub programs. Sub programs or sub routines can be defined as procedures or functions. Some programming languages don't define procedures as a separate sub program, instead they use void functions, ie functions that don't have a return value. The use of parameters promotes programming modularity, reducing code coupling to global variables. Good software engineering promotes low coupling. This video describes the difference between pass by value and pass by reference and uses a simple programmed code and output to demonstrate their use.
