Choosing the menu and ordering the menu. Creating the bill and print the bill.
The aim of this assignment is to present the knowledge the students have gathered this module; ‘C ++ programming’. The assignment is divided into their respective sections, and each section has its own objectives, which are to be achieved successfully.
Basic fact finding techniques have been followed and the preliminary investigation has been conducted to find out the problems faced by Puff and Fresh Restaurant. The current manual billing system consists of errors mentioned below.
Puff and fresh has daily customers. The Bills are stored in files and when the administration needs to access a particular bill, they have to manually go through the files and find it. This is often time consuming and can be a tiresome task.

A full feasibility study has been conducted and its results show that a computerized system for Puff and fresh is economically, legally and technically feasible to implement.
3. Solution for the problem.
The preliminary investigation has given a clear idea about the problem the Puff and Fresh is currently facing. It is clear that the Restaurant needs a computerized system to run and manage the Bill process.
Prototyping life cycle model been chosen as the appropriate life cycle model to be used to implement the system. Results from the E-R diagrams and the data flow diagrams have given an idea about the entities and their relationships.
The new computerized system has been designed and created in a manner to solve all the problems the Restaurant is currently facing.
Entering no of adults: The computerized system is created to identify the amount of adults. This reduces the work of the staff by preventing manual entry of the number and so it prevents errors.
Entering no of children’s: The computerized system is created to identify the amount of children’s. This reduces the work of the staff by preventing manual entry of the number and so it prevents errors.
Requesting orders: this program can identify the request orders without any errors.
The system is password protected and the users have to enter a password to log into the system. This prevents unauthorized users logging into the system.
4. Flowcharts and pseudo codes for the system.

If enter id and password = id and password is true then
Print “user authenticated press enter to login the program”
Else
Print “no such login information you entered user id of password invalid please try again…”
End if
Close file
While
Enter user id and password! = administrator, password
End while
Return
