PASCAL: Arrays of records

ARRAYS OF RECORDS
can also be created, in the same way as arrays of any of the four basic data types. The following statement declares a record called date.


	type  date = record
	                 month, day, year : integer
	             end;

Lets now create an array of these records, called birthdays.


	var   birthdays : array[1..10] of date;

This creates an array of 10 elements. Each element consists of a record of type date, ie, each element consists of three integers, called month, day and year.

Pictorially it looks like,

             |----------------|
             |     month      | <----<----------------
             |----------------|      |                |
             |      day       |      |--Element 1     |
             |----------------|      |                |
             |     year       | <----                 |
             |----------------|                       |
             |     month      | <----                 |
             |----------------|      |                |
             |      day       |      |--Element 2     |
             |----------------|      |                |--< birthdays
             |     year       | <----                 |
             |----------------|                       |
                                                      |
             |----------------|                       |
             |     month      | <----                 |
             |----------------|      |                |
             |      day       |      |--Element 10    |
             |----------------|      |                |
             |     year       | <----<----------------
             |----------------|

Consider the following assignment statements.


	birthdays[1].month :=    2;
	birthdays[1].day   :=   12;
	birthdays[1].year  := 1983;
	birthdays[1].year  := birthdays[2].year;

which assign various values to the array elements.
