[Year 12 SofDev] data structures - records

[Peter Hatigan]

SD U3O2 KK03- types of data structures, including one-dimensional arrays,
records and files

 

 

Does 'records' refer to:

 

Creating links to a database (Access) and manipulating records through
datasets etc.

 

Or, to creating and manipulating records within the code?

 

For example:

 

Type

    Str25    = String[25];

    TBookRec = Record

                Title, Author,

                ISBN  : Str25;

                Price : Real;

               End;

Var

    myBookRec : TBookRec;

 

Begin

myBookRec.Title  := 'Some Book';

myBookRec.Author := 'Victor John Saliba';

myBookRec.ISBN   := '0-12-345678-9';

myBookRec.Price  := 25.5;

 

Writeln('Here are the book details:');

Writeln;

Writeln('Title:  ', myBookRec.Title);

Writeln('Author: ', myBookRec.Author);

Writeln('ISBN:   ', myBookRec.ISBN);

Writeln('Price:  ', myBookRec.Price);

Readln;

End.

 

 

Or, both?
