Exercise $10\mathrm{.}0$

TASK: Declare an enumerated type $($enum$)$ that can hold the values of each state required to implement the state machine in "state$\_$machine$\_$tut$10.$png$".$

Use meaningful names for each enum value.

TIP: Use the "typedef" keyword to create a type alias for your enum.

Use the name of each state for the corresponding enum value

Enumerated types

An enumerated type or enum in $C$ allows you to declare a new type which has a finite number of defined values

The syntax for declaring a new enum type is:

enum idetifier $\{$

VALUEO,

VALUE$1,$

VALUEO

As with structs and unions, anonymous enums can be declared.

Enums are treated internally by the compiler as integers $($by default the first element is assigned the value $0,$ then $1$ for the next etc.$),$ but you should never rely on this fact

Example enum declaration and use

typedef enum $\{$ RED, GREEN, BLUE

$\}$ colour;

colour my$\_$colour $=$ RED;

int main$()\{$

If $(my\_$colour $==$ RED$)\{$

printf$("$My colour is red. $\}$

${(}^2$;
