Customer Billing System Project is a
simple console application designed to demonstrate the practical use of C
programming language and its features as wells as to generate an
application which can be used in any departmental store, shops, cafes
etc. for billing to the customer.
You can use this application to keep the
records such as name, address, mobile number, paid amount, due amount,
payment date etc. of your regular costumer. Moreover, if you have a new
customer, you can add and edit the account at any time.
The source code of Customer Billing
System Project in C has been written in C programming language without
of the use of any graphics. The code is complete, totally error free and
not that long – just. It is to be compiled in Code::Blocks using GCC
compiler. You can directly download the source code from any of the
links provided here.
Customer Billing System Project Abstract:
User Defined Functions Used:
Although graphics has not been used in
this project, the application of user defined functions and structures
have been effectively used here. The major user defined functions used
in this C project are:
- void input()
- void writefile()
- void search()
- void output()
The function void input() is
used to add the new customer account i.e. with the help of this
functions the parameters such as name, address, phone number, amount
paid etc. are asked and entered. Another function void writefile() has been utilized to create a file on hard disc of computer for storing the information and data of a customer.
The function void search() has
been used to look for previously stored accounts either by name or by
number of the customer. The fourth and the last user defined function
used in this Customer Billing System Project in C is void output() which has been defined to show the result as console output.
In Customer Billing System, structure has
very beautifully used to group the data type in single unit. The date
variables (day, month and year) have been grouped in the structures
named date where as other variables such as name, number, street, paid amount etc. are grouped under another structure named account.

- To exit
As per your need, enter 1, 2,or 3 and follow the instructions provided by the application itself.
Features:
- It can hold any number of accounts and account can be added to the program at any time.

- If you have nothing to do with the program, you can directly exit from the main menu.
Output Screens:
The project can be used in many aspects,
firstly the application file generated can be used. Secondly the source
code of Customer Billing System project in C can be used to learn C
programming and its different features such as use of user defined
functions, structures etc. Submitting this C project as your
college/school C project without any modifications is completely
discouraged.
