Introduction:Fast food automation system is a program based on C language. Generally ,in

various fast food malls and stores we see a number of workers working there to give

different items to people. The head of that particular mall has to give them salaries

accordingly. By using this , fast food automation program the problem of workersas well as money get minimized to a great extent. C is a programming language

developed at Bell laboratories of USA in1972. It was designed and written by a man

named Dennis Ritchie. Possibly C seems so popular because it is reliable, simple

and easy to use.

Moreover in an industry where newer languages tools and technologies emerge

and vanish day in and day out, a language that has survived for more than three

decades has to be really good .An opinion that is often heard today is –“C language

has been already superceded by languages like C++, C# and JAVA.

My project is program on fast food automation system using C language .

Proposed system:(a) Description:

Windows XP professional

Microsoft windows

(b) System requirements:

PC (RAM): 256 MB



LAPTOP (RAM): 1 GB

Requirement Analysis:Keywords

Keywords are identifiers reserved by the language for special use. Although

you can use them for preprocessor macro names, it is considered poor

programming style. Only the exact spelling of keywords is reserved. For

example, auto is reserved but AUTO is not.

Break:

Passes control out of the compound statement.

The break statement causes control to pass to the statement following the

innermost enclosing while, do, for, or switch statement. The syntax is simply

break;

int, char

Basic data types (integer and character)



Variables of type int are one machine-type word in length. They can be

signed (default) or unsigned, which means that in this configuration of the

compiler they have by default a range of -32768 to 32767 and 0 to 65535

respectively, but this default may be changed if the compiler option '-

mnoshort' is given. In this case, the range of type int is -2147483648 to

2147483647 for signed case, or 0 to 4294967295 for unsigned case. See also

short and long type modifiers.

Variables of type char are 1 byte in length. They can be signed (this is the

default, unless you use the compiler option '-funsigned-char') or unsigned,

which means they have a range of -128 to 127 and 0 to 255, respectively.

All data types may be used for defining variables, specifying return types of

functions, and specifying types of function arguments. For example,

int a, b, c; // 'a', 'b', 'c' are integer variable

All data type keywords may be used in combination with asterisks, brackets

and parentheses, for making complex data types, like pointer types, array

types, function types, or combinations of them, which in the C language may

have an arbitrary level of complexity (see asterisk for more info).

switch, case, default:

switch causes control to branch to one of a list of possible statements in the

block of statements. The syntax is

switch (expression) statement



The statement statement is typically a compound statement (i.e. a block of

statements enclosed in braces). The branched-to statement is determined by

evaluating expression, which must return an integral type. The list of possible

branch points within statement is determined by preceding substatements

with

case constant-expression :

where constant-expression must be an int and must be unique.

Once a value is computed for expression, the list of possible constant-

expression values determined from all case statements is searched for a

match. If a match is found, execution continues after the matching case

statement and continues until a break statement is encountered or the end of

statement is reached. If a match is not found and this statement prefix is

found within statement,

default :

execution continues at this point. Otherwise, statement is skipped entirely.

void

Empty data type.

When used as a function return type, void means that the function does not

return a value. For example,

void hello (char *name)

{

printf("Hello, %s.", name);



}

When found in a function heading, void means the function does not take any

parameters

while

Repeats execution while the condition is true.

Keyword while is the most general loop statemens. It uses the following

syntax:

while (expression) statement

statement is executed repeatedly as long as the value of expression remains

nonzero. The test takes place before each execution of the statement. For example,

while (*p == ' ') p++;

Of course, statement may be a compound statement as well.

System design:Please choose from the following:

1. Press M to see the menu

2. Press B to see generate bill

3. Press E to exit



4. Press any key to continue

Future scope of Project:



The program on fast food automation system using C language will

have a significant future scope in various fast food malls. This

program has a vast application in the future.

Nowadays we see in many stores like RELIANCE FRESH and MORE

FOR U malls, a number of workers work there and salaries are

given to them respectively. While using this program ,the money

that is given to the workers will be saved and there is no need for

applying numerous workers .So the money problem as well as

workers problem will be tackled in a sophisticated and easier

manner. The bill problem will also get reduced.
