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.
