• Arrays are defined with [ ] after the name
• They can have const or non-const array types
• We use the index to access elements of the array, starting at 0 (rather than 1)
  
  

We tend to use UpperCamelName for the enum-type and ALL_UPPER_SNAKE_CASE for the member-names.

An enum defines a type so it doesn't use an equals sign!!

Each member-name represents a const int i.e. 0,1,2,3... etc

This can be used to index arrays or for switch case labels.

A switch is a much nicer way of writing an if - else if - else-if - else-if ... statement
