The document describes a C++ program that implements a customer information system. The program allows users to add, list, modify, delete, search, and pack customer records stored in a .dat file. It features a main menu with these options. Selecting add, modify, or delete allows editing customer details like ID, name, address, phone number. Pack permanently removes deleted records to recover space. The source code and executable will be provided on next month's disc.

PUZZLEGAME
H
ere’s a puzzle game implemented
through a program written in C
with graphics mode. The program,
when compiled and run, leads you to a
screen containing 16 small squares en-
closed in a square board. There are 15
numbers placed in 15 squares, the 16th
square being left blank. The numbers in
the squares are randomly arranged. The
players have to arrange the numbers in
ascending order in minimum number of
moves through navigation (arrow) keys.
This program is designed for two
game players. The first player attempts to
arrange the numbers in ascending
order in minimum number of moves to
finish the game. Every move is recorded
and shown in the scoreboard at the
upper right-hand corner of the screen.
When the player completes the puzzle, he
must note down the total number of moves
made by him from the scoreboard. Now
the second player attempts to arrange the
numbers in ascending order in minimum
number of moves and the number of
moves made by him are displayed on the
scoreboard. The player who completes
the puzzle with the least number of moves
is the winner.
To get started, double click on the file
puzzle.exe or, if you are using DOS
prompt, type ‘puzzle’ (or whatever name
you choose to save in your system). When
the first screen appears, press any key to
SANI THEO
continue. Now you get the final screen
containing 16 small squares in a square
board as shown in the screenshot. Use
navigation keys or up/down arrow keys
to move the desired number into blank
box, in order to arrange the numbers in
the ascending order. Press Esc key to quit

CUSTOMER INFORMATION SYSTEM
P
eople in organisations come across
many a person in their day-to-day
life. In order to have instant access
to any person, it is essential for the
organisations to maintain the contact ad-
dresses, telephone number, etc of impor-
tant persons in an organised manner. This
can be successfully achieved with a PC.
Here’s a program written in C++ that
makes this possible. Note that it is not a
graphics-based program.
After compilation when you run
the program, it prompts you to press any
key. On pressing any key from the
keyboard, the main menu appears
on the screen as shown in the screenshot.
The main menu has options like
Add Records, List Records, Modify
Records, Delete Records, Recall Records,
Pack Records, Search Records, and
Exit. The details of these options are as
follows:
1. Add Records: It allows you to add
new records.
2. List Records: It shows all the records
page by page.
3. Modify Records: To modify the con-
tents of the existing records.
SANI THEO
4. Delete Records: To delete any record.
5. Recall Records: To recover all the
deleted records.
6. Pack Records: This option com-
pletely removes all the deleted records.
Note that once this option has been se-
lected, the deleted files cannot be recov-
ered.
7. Search Records: To search a par-
ticular record from the existing records.
8. Exit: It allows you to quit from the
