C

2. • You will got to know about the various
computer languages
• History of C Language.
• How Program is developed.

3.  You will know about the basics of C language
and can answer where C is used and can be
used.
 How various Compilers and Graphics
programs can be made by using C language.
 What are the various steps Developer needs
to follow while working on a project.

4.  Language
 Programming
 History of C Language
 Program Development

5.  Source of Communication between
two persons.
◦ Example: Human –To- Human
OR
 Source of Communication between
User and Computer is called
programming language.
◦ Example: Human –To- Machine

6. Set of instructions which perform
any specific task is called program.

7.  Series of instructions given to a computer to
achieve a task
 Instructions must be written in a way the
computer can understand
 Programming languages are used to write
programs
 Once the code (language) of a program has been
written, it must be executed (run, started).
 Some programming languages (like C, C++ or
Java) require the code to be compiled (translated
to binary) before it can be started.

9.  C
 A language written by Dennis
Ritchie in 1972 at AT&T Bell Labs
USA. This was to be the language
that UNIX was written in to become
the first "portable" language.
In recent years C has been used as a general-purpose
language because of its popularity with
programmers.
AT&T-American Telephone and Telegraph
UNIX-Uniplexed Information and Computing System or Service

10.  C provides:
 Efficiency, high performance and high quality
 Provide functionality through rich set of function libraries
 Gateway for other professional languages like C  C++ 
Java
 C is used:
 System software, Compilers, Editors
 Graphics and Geometry
 Databases, operating systems, device drivers
 Also used in application programs

11.  Requirement Specification
◦ Problem Definition
 Analysis
◦ Refine, Generalize the problem definition
 Design
◦ Develop Algorithm: (A formula or set of steps for solving a
particular problem)
 Implementation
◦ Write Code
 Verification and Testing
◦ Test and Debug the code
 Maintenance

12.  Decide what steps are needed to complete the task
 Write the steps (Algorithm) in pseudo code (written in
English) or as a flowchart (graphic symbols)
 Translate into the programming language
 Try out the program and “debug”.

13.  We have seen about the language. What
language does, History of C Language, What
programming is this will help you in the
coming lectures.
