The last update of the Web page on: 9 June 2002.


Solutions:

Solution for the When Delphi Project (it determines a date which is 7 days after a given date).

WhenPro.exe: Executable file for WHEN Delphi Project.

When.zip: A directory (A1) with all files of the WHEN Project, including Pascal source code.

Solution for the Tank Delphi Project (it determines whether a car's tank is full after purchasing a given amount of petrol).

TankPro.exe: Executable file for TANK Delphi Project.

Tank.zip: A directory (A1) containing all files of the TANK Project, including the Pascal source code.

Solution for the DayNo Delphi Project (it determines what is the current number of a given day of the year).

DayNoPro.exe: Executable file for DayNo Delphi Project.

DayNo.zip: A directory (A1) containing all files of the DayNo Project, including the Pascal source code.


Problems:

Text of Delphi problems. (It contains descriptions of programming problems, for which which solutions are given here.)

Text of Assignment 1 (in WORD *.doc format).


Instructions:

(1) Each solution presented here was done in Borland Delphi 6 (Professional).
(2) Each Delphi solution consists of at least 13 separate files. Note that Delphi 6 version does not like any of the files is missing, and does not tolerate the moving of files around. Before you get through the trouble of dowloading to your computer all these files, check first by dowloading the *.exe file as in item (3) below, whether you are interested in analysing this particular solution.
(3) In order to download to your computer (in order to test how it works) the executable version of a given solution (*.exe), click on it, and when the system asks you where to save it, provide a name of the directory from which you wish to run it.
(4) In order to download to your computer all the remaining files of a given solution, click on the *.zip file, download this *.zip file to your computer, and then unzip this file in the directory in which you wish to execute it. (Note that all solutions available here were prepared to be run from a floppy diskette A:, and that they are all zipped as the entire directory A1).
