PASCAL DATA TYPES
2.3.1.5 Array Examples -
Example 1
TYPE Times = 1 •• 10;
VAR Raceresults : ARRAY[1 •• 50J OF Times;
I : I NTEGEfn
BEGIN
FOR I := 1 TO 50 DO
Raceresults[IJ != 0
END;
This example decl~res the variable Raceresults as a 50-component array
of Times. The FOR statement assigns zero to each component in the
array.
Example 2
T Y P E f:) t, r i n 9 ,,: PAC KED A F~ RAY [1.. 1 () ] 0 F C H A FU
VAR Composer, Word, Empt~ : String;
BEGIN
END;
Word := 'engrossing';
Composer := 'C.P.E.Bach';
EITJPt~:J ::::: I
This example declares three string variables. It assigns string
constants to the variables Word and Composer, and assigns a string of
10 spaces to the variable Empty.
Example 3
CONST Da\.~~:; :::: 31;
TYPE Weather:::: (Rain, Snow, Sunn~, Cloud~, Fogg~);
Month = ARRAY C1 •• DAYS] OF Weather;
This example shows how you can use a constant identifier in the index
type. The indices of arrays of type Month range from 1 to the value
of the constant Days.
2.3.2 Record Types
The record is a convenient way to organize several related data items
of different types. A record consists of one or more fields, each of
which contains one or more data items. Unlike the components of an
array, the fields of a record can be of different types. The record
type definition specifies the name and type of each field.
