The document provides an overview of C and C++ programming languages, including their history, features, and applications. C is a general-purpose procedural language developed for Unix, while C++ is an object-oriented extension of C that incorporates classes and advanced features. The document also mentions various advantages, comparisons, and applications of both languages in modern software development.

3. What is C ?
• C is a high-level and general purpose
programming language that is ideal
for developing firmware or portable
applications. Originally intended for
writing system software.

4. • C was developed at Bell Labs by
Dennis Ritchie for the Unix
Operating System (OS) in the early
1970s.
• Ranked among the most widely used
languages, C has a compiler for most
computer systems and influenced
many popular languages – notably
C++.

5. History of C
• C is a general-purpose programming language.
• C is a programming language which born at “AT &
T’s Bell Laboratory” of USA in 1972.
• C was written by Dennis Ritchie, that’s why he is
also called as father of c programming language.
• C language was created for a specific purpose i.e.,
designing the UNIX operating system (which is
currently base of many UNIX based OS From the
beginning, C was intended to be useful to allow
busy programmers to get things done because C is
such a powerful, dominant and supple language
• Its use quickly spread beyond Bell Labs in the late
70’s because of its long list of strong features.

6. History of C
• C language was created for a specific
purpose i.e., designing the UNIX
operating.
• Its use quickly spread beyond Bell
Labs in the late 70’s because of
its long list of strong features.

7. Features of C
• Fixed number of keywords, including a set
of control primitives, such as if, for, while,
switch and do while
• Multiple logical and mathematical
operators, including bit manipulators
• Multiple assignments may be applied in a
single statement.

8. Features of C
• Function return values are not always
required and may be ignored if
unneeded.
• Typing is static.
• Basic form of modularity, as files
may be separately compiled and linked
• Control of function and object
visibility to other files via extern and
static attributes

9. Advantages
• Procedure Oriented language
• Lots of Libraries
• Speed of Compilation
• Easy to Learn
• Portable
• It follows top – down approach

10. Applications of C
• C language is used for creating computer applications
• Used in writing Embedded software's
• Firmware for various electronics, industrial and
communications products which use micro-controllers.
• It is also used in developing verification software, test
code, simulators etc. for various applications and
hardware products.
• For Creating Compiles of different Languages which
can take input from other language and convert it
into lower level machine dependent language.
• C is used to implement different Operating System
Operations.
• UNIX kernel is completely developed in C Language.

11. Applications of C
• For Creating Compiles of different
Languages which can take input from
other language and convert it into
lower level machine dependent language.
• C is used to implement
different Operating System Operations.
• UNIX kernel is completely developed in
C Language.

12. Some More Applications of C
Operating Systems Network Drivers Print Spoolers
Language compilers Assemblers Text Editors
Modern Programs Data Bases Language Interpreters
Simulators Utilities Embedded System

13. What is C++ ?
• C++ is a general purpose object oriented
programming language. It is considered to
be an intermediate level language, as it
encapsulates both high and low level
language features. Initially, the language
was called 'C with classes’ as it had all
properties of C language with an additional
concept of 'classes’. However, it was
renamed to C++ in 1983.
• It is pronounced as "C-Plus-Plus."

14. History of C++
• C++ Development started in 1979.
• During the creation of Ph.D. thesis, Bjarne
Stroustrup worked with language called Simula.
• Bjarne Stroustrup identified that this OOP
features can be included in the software
development.
• After that Bjarne Stroustrup started working
on the C language and added more extra
OOP features to the classic C.
• C++ includes features such as classes,
inheritance, in-lining, default function
arguments, and strong type checking.

15. History of C++
• After that Bjarne Stroustrup started
working on the C language and added
more extra OOP features to the
classic C.
• C++ includes features such as classes,
inheritance, in-lining, default function
arguments, and strong type checking.

16. Features
• Simple
• Portability
• Powerful
• Platform dependent
• Object oriented
• Case sensitive
• Compiler based
• Syntax based language
• Use of Pointers

17. Applications of C++
• Google : Google uses C++ for indexing.
• Adobe Systems : All major software like
Photoshop, Adobe Premiere are made in C++.
• Mozilla : Mozilla Firefox and Thunderbird are
written in C++.

18. Applications of C++
• VLC media player is written in C language.
Many parts of Operating systems are
written in C/C++. And the very powerful
Linux is completely written in C.
• MySQL : The very powerful database
management application

19. Advantages
• Simple
• Secure
• Portable
• Object-Oriented
• Robust
• Multithreaded
• Interpreted
• Provides high
performance
• Distributed
• Dynamic

20. C C++

Function is difficult and
complicated.
9. Mapping between Data and

22. 11. C requires all the variables to
be defined at the starting of a
scope.

of variable anywhere in the
scope i.e. at time of its First
use.
