Pseudo Code

Is a computer program that is written in plain English.  It cannot run on as a program.  It is used to plan a program before the actual code or blocks are assembled.  It is often used with flowcharts.  Pseudo code is often used in computer science exams when the examiner does not require specific knowledge of a particular program.
