Stock and Bill Management Project

I have made this project for your practice only this is live project running in whole sale shoes shop. You can use this project as your course final project because I have seen many students who buy project from market or internet so I made this project online for download every one with free of cost. I also suggest student who’re going to make this project as their course project, please take a look on project and understand what the flow of this project working model are. I don’t want to make use this project as shortcut to only submitting your project. No! This is wrong so try to learn some live coding from this project. 

Commercial use of this project without consent  is prohibited.

Project Description

This helps to manage stock and billing of a whole shale shop. Primary this project was design for a shoes shop but it can be apply the business which sells some company project which has further some sub type. All the entry left blank. So you can create your own entry. Some demo records are in download database for sake for understood of project work flow. One you will be understands work flow then you customize this project as your requirement.

Inheritance OOP

Inheritance (Object Oriented Programming)

In object-oriented programming,Inheritance allows us to define a class which is based on another class, which makes it easier to create and maintain an application. This also provides an opportunity to reuse the code functionality and fast implementation time.The derived class is also called subclass and the base class is also known as super-class. The derived class can add its own additional variables and methods. These additional variable and methods differentiates the derived class from the base class.inheritance saves our money and time both because we use predefined compile and tested class which increase quality of software.

Function Pointer

   Function pointer is a type of pointer which points a function or code block. You can assign address of a function to function pointer variable and that function using function pointer variable name.

   I have a bad experience while making Calculator. In my design all the calculation takes place when user pressed equal button. When a user pressed equal button I need to check every time which operator user was pressed , checked by switch case, it become complicated then I increase more function in my calculator because of lots condition for operator check and attached code for particular logic separately.

   Now my work becomes simple because of function pointer because I just need to check operator pressed by user and attached related function code to function pointer. It reduces lots of condition checking and assigns separate code to each section. So function pointer is very useful in some specific scenario.

Advantage of function pointer

• Implement Callback
• Useful in event handling
• One entry point for more than one code block

C language function precedence
