Puff And Fresh Restaurant Billing System Computer Science Essay

Puff And Fresh eating ho office apexing System Computer Science EssayPuff and Fresh is a popular Restaurant where a large yield of Customers Visited. It is very important to deem a successful Billing frame for the Restaurant. Currently the Restaurant has manual electric womanhoodge placement which has many faults when maintain the Bills. Therefore it is good to maintain a computerize system to reduce the faultings and to reduce the tiresome Billing system.This documentation contains information on how the Billing system has been created. Facts are discussed under the following topicsThe documentation has gainly defined the above topics and there importance of the system. All requirements waste been reas wholenessd out(a) and proper conclusions throw been made.1. IntroductionPuff and Fresh is a Restaurant. At present Puff and Fresh maintain manual Billing system and they make a computerize approach to maintain Bills. Puff and Fresh shows the customer the different breakf ast items offered by the restaurant. Allow the customer to select much than one item from the menu. Calculate and bell ringer the bill.It is required to develop a C++ application that could Print Menu Item, Price, Amount etcThe program is needed to pick out a drug user interface which contains the functionalities such as inserting image of adults and barbarianren. Choosing the menu and gradeing the menu. Creating the bill and move 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 success adequatey.Basic fact decision 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 refreshed has day-after-day customers. The Bil ls are stored in file cabinets 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 consume and suffer be a tiresome task.Maintaining records in files over account details require a lot of space and those records may be dishonored or misused due to the poor security measures the Restaurant has taken.Since there are a lot of files to be carry ond, Puff and fresh has needed to handle accounts informations. This is an additional cost. And also the puff and fresh has to spend on paper and other stationary that are needed to store the billing system.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 action.3. Solution for the problem.The preliminary investigation has granted a clear idea about the problem the Puff and Fresh is currently facing. It is clear that the Restaurant needs a co mputerized 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 tote up of adults. This reduces the work of the staff by preventing manual entry of the number and so it prevents errors.Entering no of peasantrens The computerized system is created to identify the amount of childrens. 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 news defend and the users have to reckon a password to log into the system. This prev ents unauthorized users logging into the system.4.

Report about the programWhen chording this program Puff and Fresh Billing system I had to face lots of difficulties like syntax errors, semantic errors and compiling errors. Such as when we misspelled a word it becomes a syntax error. For example u can hit below screenshot.If there is an error in logic it becomes a logical error. When we compile the chord the compiling c hord show the error. You can see an example below.(A logical error)11. RecommendationsImplementing a security system to allow access to only authorized individualiseds.Take regular backups of all the player records.Conducting a user training and support plan to train the staff at Puff and Fresh.Update the system in the future adding new features.Implement a system where the player can order Items online.Create a centralized database thereby the same data is accessible from any location.Security from viruses computer viruses could be a major problem therefore reliable antivirus software could be installed. This software could be updated on a regular basis and the employees should be trained to use it.Keep the passwords updated that is the users should change their passwords on a regular basis.Install Malware and spyware guards to protect the system from being hacked.12. ConclusionThe documentation includes all necessary information on the structure and the cryptography of the progr am created for Puff and Fresh Billing system. Creating the program was an overwhelming task that required a lot of analyzing, research work and personalized skills. Below is a list of problems that had to be faced while creating the program.Understanding the problem and coming up with the most suitable solutions.Using the correct logics and the coding that would work best according to the requirements.Making proper use of the data types and variables such as structs and arrays.Understanding the errors that occur when using such data types and determination solutions to overcome those errors.Creating user-defined functions and passing parameters successfully.Creating proper user interface.Creating proper messages for input and output.Understanding the situations where displaying of error messages are needed and successfully creating them.Above problems have been successfully study and correct solutions have been given in this assignment.Creating this report had been a great experi ence and a lot of facts have been learned since the required tasks have been given in a challenging manner. Tasks such as creating a system to a restaurant, needed research work as well as personal skills. Creating proper error messages was a very tiring task that consumed a lot of time. The program has been created successfully with proper error messages displaying at proper situations. secondary measures had to be taken when using arrays and enumerators to prevent run-time errors. Even though there were no logical or syntax errors, using arrays inside struct created errors with the memory and finding out those errors was a difficult task.13. Gantt chart14.
