Acknowledgement
I am very thankful and expressing my deep sense of gratitude
towards Miss Sukhdilpreet Kaur, Lecturer LSE, Lovely
Professional University, who inspired me to work on this topic.
I benefited a lot with discussing him on this topic.
I am also thankful to my parents who provided me such a
opportunity, for their inspiring words.
I am also thankful to all my colleagues and all those who helped
me in completion of this project.

INTRODUCTION OF C
As a programming language, C is rather like Pascal or FORTRAN.
Values are sorted in variables. Programs structured by defining and
calling functions. Program flow is controlled using loops, if statement
and function calls.
Input and output can be directed to the terminal or to the file
.Related data can be sorted together in array or structures.Of the three
languages, C allows the most precise control of input and output .C is
also rather more terse than FORTRAN and PASCAL .this can result in
short efficient programs where the programmer has made wise use of C
range of powerful operators. It also allows the programmer to produce
which are impossible to understand.
Programmer who are familiar with the use of pointers (or
indirect addressing, to use the correct term) will welcome the ease of
use compared with some other languages .Undisciplined use of pointer
can lead to errors which are very hard to trace .This course only deals
with the simplest applications of pointers.

It is that newcomer will find C a useful and friendly language. Care
must be taken in using C. many of the extra facilities which it offers can
lead to extra types of programming error. You will have to learn to deal
with these to successfully make the transition to being a C programmer.
Why use C?
C has been used successfully for every type of programming
problem imaginable from operating systems to spreadsheets to expert
system – and efficient compilers are available for machines ranging in
power from the Apple Mocintosh to cray supercomputer. C is often
called a “Middle Level” language.
Use of C
C was initially used for system development work, in particular the
programs that make up operating system. Why use C? Mainly because
it produces code written in assembly language. Some examples of the
use of C might be:
Operating system
Language Compilers
Assemblers

Text Editors
Modern Programs
Language Interpreters
In recent year C has been use a general-purpose language because of
it is not the world’s easiest language to learn and you will certainly
benefit if you are not learning C as your first programming language!
C is trendly many well established programmers are switching to C for
all short of reasons, but mainly because of the portability that writing
standard C programs can offer.
