typedef

enum myEnum variable becomes myEnum variable. A lot more modern looking :))

typedef double temp;
typedef enum coin { HEAD, TAIL } coinType;
typedef union braindead { int a; double b } braindead;
 
// Declare 3 variables based on abv
temp myTemperature;
coinType curCoinType;
braindead iShouldNotExist;

The example w/ the confusing yet legal thing just shows how something might confuse us but for the computer it makes sense.

• The name of the object you’re giving an alias to can be the same as the alias’s name To know the “type” a typedef would be, simply do this:

1. Remove typedef: union braindead { int a; double b } x;
2. What type is x? It’s a union of a and b
3. So typedef’s alias will represent a union of a and b
