​Functions and Procedures

Programs implement several tasks. Many times similar tasks are repeated. Typing the same code multiple times is time-consuming. Such tasks are written as modules such as functions, procedures or subprograms are written. These can be called multiple times in the main program reducing the time taken.

This GCSE Computer Science module introduces ​​functions and ​procedures to your students, explaining:

  • What they are
  • ​Sub-routines in flowchart 
  • ​What are global and local variables
