Define Enumeration in Computer Programming?

Enumerated types enclose a list of constants that are able to be addressed in integer values.

We can declare variables and types as follows.

enum days
{
mon, tues, ..., sun
} week;

enum days week1, week2;

NOTE: As with arrays first enumerated name has index value 0. So mon has value 0, tues 1, etc.

week1 and week2 are variables.

We can define other values:

enum escapes
{
bell = `\a',
backspace = `\b',
tab = `\t',
newline = `\n',
vtab = `\v',
return = `\r'
};

We can also override the 0 start value:

enum months
{
jan = 1, feb, mar, ......, dec
};

Here it is implied that feb = 2 etc.
