CHAPTER 1:- INTRODUCTION

1.1 PROJECT DESCRIPTION

FOOD AUTOMATION” aims at developing into software that can be used at places like

restaurants and fastfood points to easily manoeuvre the daily tasks of taking the order,

calculating the bill etc.

The main advantage of this project is that it converts all the manual work which is time

consuming and error prone to fully automated system which helps in eliminating all the paper

work, saves time, improves customer services. It also speeds up various processes such as

addition of new items to the menu, deletion of items from the menu, modification of details

of items and calculation of bills thus providing convenience to the workers as well as

customers.

In the development of the project, selection of an appropriate programming language and a

platform is of primary importance. The major part of the credit goes to the software

environment chosen by the developer. Selection of a language from the ocean of languages is

very difficult; a developer has to consider various features and functionalities that a particular

language can provide.

In this project C++ language is used to maintain all the data. It provides many features like

file handling ,data can be easily maintained and many features that are required while doing a

project.

1.2 PROBLEM DEFINITION

The project is developed for restaurants, which aims to automate its various tasks. All the

work of various tasks was earlier carried out manually. However in the course of time it was

realized that manual work is error prone and time consuming. Automation provides quick &

easy step by step approach to handle the tasks like adding items to the menu, deleting items ,

modifying the details of items and calculating bills. Thus automation is no longer an option,

it’s a requirement.

1.3 OBJECTIVES OF THE PROPOSED SYSTEM

To reduce time for the organization

To increase efficiency and accuracy of the system

To reduce pressure on the labour and relieving man power from repetitive and dull job

To make the retrieval of information faster

To make the system more feasible

To reduce large amount of paper work

To make the system more reliable to avoid any ambiguity.

To reduce the cost factor of the system

To make the system more flexible.

1.6 INTRODUCTION

C++ is a statically typed, free-form, multi-paradigm, compiled, general-

purpose programming language. It is regarded as a "middle-level" language, as it comprises a

combination of both high-level and low-level language features. It was developed by Bjarne

Stroustrup starting in 1979 at Bell Labs as an enhancement to the C language and originally

named C with Classes. It was renamed C++ in 1983.

As one of the most popular programming languages ever created, C++ is widely used in the

software industry. Some of its application domains include systems software, application

software, device drivers, embedded software, high-performance server and client

applications, and entertainment software such as video games. Several groups provide both

free and proprietary C++ compiler software, including the GNU

Project, Microsoft, Intel and Borland. C++ has greatly influenced many other popular

programming languages, most notably C# and Java.

C++ is also used for hardware design, where design is initially described in C++, then

analyzed, architecturally constrained, and scheduled to create a register transfer

level hardware description language via high-level synthesis.

The language began as enhancements to C, first adding classes, then virtual

functions, operator overloading, multiple inheritance, templates, and exception

handling among other features.

1.5.1.1 OPERATORS AND OPERATOR OVERLOADING

C++ provides more than 30 operators, covering basic arithmetic, bit manipulation,

indirection, comparisons, logical operations and others. Almost all operators can

be overloaded for user-defined types, with a few notable exceptions such as member access

(. and .*). The rich set of overloadable operators is central to using C++ as a domain specific

language. The overloadable operators are also an essential part of many advanced C++

programming techniques, such as smart pointers. Overloading an operator does not change

the precedence of calculations involving the operator, nor does it change the number of

operands that the operator uses (any operand may however be ignored by the operator,

though it will be evaluated prior to execution). Overloaded "&&" and "||" operators lose

their short-circuit evaluation property.

1.5.1.2 TEMPLATES

C++ templates enable generic programming. C++ supports both function and class templates.

Templates may be parameterized by types, compile-time constants, and other templates. C++

templates are implemented by instantiation at compile-time. Templates are a powerful tool

that can be used for generic programming, template metaprogramming, and code

optimization, but this power implies a cost. Template use may increase code size, since each

template instantiation produces a copy of the template code: one for each set of template

arguments. Templates are different from macros: while both of these compile-time language

features enable conditional compilation, templates are not restricted to lexical substitution.

Macros are capable of conditional control over compilation based on predetermined criteria,

but cannot instantiate new types, recurse, or perform type evaluation and in effect are limited

to pre-compilation text-substitution and text-inclusion/exclusion. Macros can control

compilation flow based on pre-defined symbols but cannot, unlike templates, independently

instantiate new symbols.

1.5.1.3 OBJECTS

C++ introduces object-oriented (OO) features to C. It offers classes, which provide the four

features commonly present in OO languages: abstraction, encapsulation, inheritance,

and polymorphism. Objects are instances of classes created at runtime. One distinguishing

feature of C++ classes compared to classes in other programming languages is support for

deterministic destructors, which in turn provide support for Resource Allocation is

Initialization concept.

1.5.1.4 ENCAPSULATION

Encapsulation is the hiding of information in order to ensure that data structures and

operators are used as intended and to make the usage model more obvious to the developer.

C++ provides the ability to define classes and functions as its primary encapsulation

mechanisms.

1.5.1.5 INHERITANCE

Inheritance allows one data type to acquire properties of other data types. Inheritance from a

base class may be declared as public, protected, or private. Virtual inheritance ensures that

only one instance of a base class exists in the inheritance graph, avoiding some of the

ambiguity problems of multiple inheritance.

1.5.1.6 POLYMORPHISM

Polymorphism enables one common interface for many implementations, and for objects to

act differently under different circumstances. C++ supports several kinds of static (compile-

time) and dynamic (run-time) polymorphisms. Compile-time polymorphism does not allow

for certain run-time decisions, while run-time polymorphism typically incurs a performance

penalty.

C++ is designed to be a statically typed, general-purpose language that is as efficient

and portable as C

C++ is designed to directly and comprehensively support multiple programming

styles ( procedural programming, data abstraction, object-oriented programming,

and generic programming)

C++ is designed to give the programmer choice, even if this makes it possible for the

programmer to choose incorrectly

C++ is designed to be as compatible with C as possible, therefore providing a smooth

transition from C

C++ avoids features that are platform specific or not general purpose

C++ does not incur overhead for features that are not used (the "zero-overhead

principle")

C++ is designed to function without a sophisticated programming environment

C++ has certain characteristics over other programming languages. The most remarkable are:

Object-oriented programming

The possibility to orientate programming to objects allows the programmer to design

applications from a point of view more like a communication between objects rather than on

a structured sequence of code. In addition it allows a greater reusability of code in a more

logical and productive way.

Portability

You can practically compile the same C++ code in almost any type of computer and

operating system without making any changes. C++ is the most used and ported

programming language in the world.

Brevity

http://en.wikipedia.org/wiki/Procedural_programming

http://en.wikipedia.org/wiki/Data_abstraction






Code written in C++ is very short in comparison with other languages, since the use of

special characters is preferred to key words, saving some effort to the programmer (and

prolonging the life of our keyboards!).

Modular programming

An application's body in C++ can be made up of several source code files that are compiled

separately and then linked together. Saving time since it is not necessary to recompile the

complete application when making a single change but only the file that contains it. In

addition, this characteristic allows to link C++ code with code produced in other languages,

such as Assembler or C.

C Compatibility:

C++ is backwards compatible with the C language. Any code written in C can easily be

included in a C++ program without making any change.

Speed:

The resulting code from a C++ compilation is very efficient, due indeed to its duality as high-

level and low-level language and to the reduced size of the language itself.

2.3 SYSTEM DESIGN

This section of the project involves the division of project in some modules or parts thus

making the presentation of the project clear and easily understandable. We have discussed

below various modules and part of project they contain.

2.4 MODULES (DESCRIPTION)

This project mainly consists of two menus:

EDIT MENU

MAIN MENU

• EDIT MENU

• ADD ITEM

• DELETE ITEM

12



• MODIFY ITEM

• QUIT

• MAIN MENU

• PURCHASE

• SEE MENU

• EDIT MENU

• TOTAL BILL

• QUIT

ENTER CHOICE

Now here when we choose the first option i.e. PURCHASE, we need to mention the

item code of the item to be purchased. After this the complete details of the item is

displayed. Then we are required to mention the quantity, whether we want to cancel

this purchase or not

After this total bill is calculated and displayed along with the complete details of

items.

When we choose the second option i.e. SEE MENU, following details of the list of

items is displayed:

• ITEM CODE

• ITEM NAME

• ITEM COST

• ITEM PRICE

Now when we choose the third option EDIT MENU following options are displayed:

• ADD ITEM

• MODIFY ITEM

13



• DELETE ITEM

• EXIT

ENTER CHOICE:

Now here when we choose the first option i.e. ADD ITEM, we need to specify the

following details of the item:

• ITEM NAME

• ITEM COST

• ITEM PRICE

Thereafter we have to decide whether we want to save the record or not and hence choose

one of the options: y/n. When we choose y our record is saved otherwise not. Then we add

more items according to the requirement.

Now when we choose the second option i.e. MODIFY ITEM, we need to specify the

item code of the item to be selected and then modify the details of the items as per the

requirement by choosing the correct options.

When we choose the third option i.e. DELETE ITEM, we need to specify the item

code of the item to be deleted. Thereafter the selected item is deleted from the menu.

We can choose the fourth option i.e. EXIT to exit the menu.

14



We can choose the fourth option of the main menu i.e. TOTAL BILL to display the

total bill of the items purchased

3.1. WORKING OF THE PROJECT

In this project we have three classes:

CLASS MENU

CLASS FOOD

CLASS ACCOUNT

In class menu there are two main functions:

Edit _menu

Main _menu

In case of main menu we have following options:

1 PURCHASE

2 SEE MENU

3 EDIT MENU

4 TOTAL BILL

0 EXIT

In case of purchase we have to mention the item code of the item to be purchased and

quantity. Thereafter bill is displayed. For this we have purchase function

When we choose see menu list of items along with its details such as item code, item cost and

item price is displayed. For this we make use of see menu function

In case of Edit menu we have following options:

ADD ITEM

DELETE ITEM

17



MODIFY ITEM

EXIT

In case of add item we mention the item name, item price and item cost for the item to

be added and thus the item is added in the menu.

In case of delete item we mention the item code of the item to be deleted.

In case of modify item we mention the item code of the item to be modified.

For this we make use of modify_item and modify_record functions.

When we choose total bill ,total bill is displayed.

In class food we have following functions:

Add_item- This function add records in the food file.

Delete_item – This function gives the code no. to delete record from the food file

Modify_item –This function gives the code no. to modify record from the food file

List_of_item- This function displays the list of food items

Purchase – This function purchases the food item in the menu

Last_code- It returns the code of the last record in the food file.

Delete_record-This function deletes the record for the given code from the food file.

(FOOD.DAT)

Modify_record – This function modify the record for the given code from the food

file

Display_record-It displays the record of the given code from the food

file(FOOD.DAT)

Item_found-This function return the value 1 if the record is found for the given code

in the food file.

18



Recordno- This function return th record no. of the given code in the food file.

Sort- This function sort the record in the food file according to the code nos.

Class account is used to calculate bill.It consists of the following functions:

Bill_list – This function displays the lists of the bills

Prepare_bill – This function prepares and displays the bill for the given bill no.

according to the purchases made.

Last_billno-This function returns the billno. of the last record in the bill file

CHAPTER 4: CONCLUSION

4.1 CONCLUSION

As we all know that a restaurant is a retail establishment that serves prepared food to

customers. Service is generally for eating on premises, though the term has been used to

describe take-out establishments and food delivery services. So this project basically

develops software that can be used at such places to easily man oeuvre the daily tasks of

taking the order, calculating the bill, modifying the details of the items in the menu etc.

This project is time saving as it saves the time of the workers as well as customers. It

calculates bill quickly and correctly. Modification of the details of the items in the

menu, addition of more items in the menu, deletion of items and keeping up of the

track of the items purchased is much more convenient.

It is also storage saving .Previously all the work was done manually and required a lot

of time. Tedious book-keeping is completely eliminated with automation. Large

amount can be stored in a single hard disk and make it easy for the user to store data

for future retrieval. The storage enhancement provide benefit in the form of cost

saving.

28



Complicated calculations can be done more easily. Thus bills can be prepared more

quickly and with more accuracy just by choosing the correct option which calculates the

bill automatically.

Optimal utilization of resources can be done. Different tasks of keeping up of the

track of the items in the menu, placing of order and calculating bill can be carried out in

different departments in a systematic way.

4.2 FEATURES OF THE PROJECT

USER-FRIENDLY:

The system will be user –friendly so that it can easily be understand by the user without any

difficulty.

EASY OF MAINTENANCE:

The system will be easy to maintain and use.

LESS TIME CONSUMING:

The system will be less time consuming, which could have achieved b y good programming.

PORTABILITY:

The system portability will have taken care of without any interventions.

ERROR FREE:

The system will easily handle the user error in any case.
