Programming project: subroutines I

Structured programming

Procedures

Functions

Global and local variables

Creating an XOR function

Programming project: subroutines II

In this unit pupils will be introduced to structured programming. They will explore the differences between functions and procedures and use functions to return values in programs. They will be introduced to the concept of scope and how parameters can be used to reduce the need for global variables.

Programming: subroutines

The project {{}} specifies what the requirements of a program are.
