A Level Computer Science: Functions and procedures
This module contains:
Compatible with the following examination boards
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 A Level Computer Science module introduces functions and procedures to your students, explaining:
- Application of functions (learnt in mathematics) in programming.
- How are functions useful to programmers?
- What are procedures? How are they different from functions?
- Passing parameters by value and by reference
