The computer shop management system has been

developed for stocking and sale of computer

hardware items from a computer shop. The program

offers a complete lists of the items available in the

shop and their respective rates.

In this C++ program we can modify, add, delete, recall

and list the records.

The products and their details are stored in the binary

file main.dat.

Being OOP concept available, we can add or remove

function anytime we need and even add classes and

derived classes for further improvement of the program

without recording.

For Windows 7, 8, 8.1, 10 –

Code::Blocks with MinGW compiler

Dev C++

Turbo C++

For Linux –

Visual Studio

Eclipse CDT

Code::Blocks

For Mac OS –

Code::Blocks

Eclipse IDE

Objective-C++

For Hardware you need to have space to install the

applications and space for saving your coding (100 MB

approx.) and need to have more than 520 MB RAM for

faster compilation.
