ABOUT C PROGRAMMING
C is a general-purpose, procedural and
imperative programming language which was
designed and developed Dennis Ritchie at Bell
Laboratory. This language is mainly intended to
re-implement the UNIX operating system. The file
extensions of this imperative language are .c and
.h. The C programming language has been
recognized by the American National Standards
Institute (ANSI). The Unix operating system, C
compiler, and all UNIX application programs are
written by using C programming language.
4
USES OF C LANGUAGE
C is a structured programming language and easy
to learn More efficient programs can be made by
using C programming language The users can
compile the C programs using various
computer platforms The most famous Linux
operating system and RDBMS MySQL are implemented
using C programming language
5
ENVIRONMENT SETUP
The users can setup the C programming language in
their environment with the help of two essential
tools such as text editor and the C
compiler. The text editor is used to write the
code. Some of the commonly using text editors
are windows notepad, brief, OS edit command,
etc. The C compiler is used to convert the human
readable source file into machine language only
then the CPU can perform execution process as
per the instruction was given.

BASIC STRUCTURE OF C PROGRAM

• The complete C program should have the following
  parts- Preprocessor commands
• Variables
• Functions
• Comments
• Statements
• Expressions
• The C programming language has various tokens
  include the identifier, constant, string
  literal, keyword, and symbol.

7
DATA TYPES IN C
Integer data types Floating point data types
Enumerated types Void type Derived date types
include the pointer, union, array, functions,
and structure.
8
VARIABLES IN C
A
Variables The variables in C language are used to
store the values that are manipulated by
programs. Some of the primary variables are

1. char
2. int
3. float
4. void and
5. double.

9
C PROGRAMMING CONSTANTS
A
Constants

• Constants are fixed values which will not be
  changed during the execution of the program. The
  constants are often referred as literals.
• Some of the commonly used constants are
• integer constant
• character constant
• floating constant and
• string constant

10
STORAGE CLASSES IN C
A
Storage Classes
Storage class means that the visibility and the
lifetime of the variables and functions within
the C program. Auto, static, extern and register
are four types of storage classes available in C
programming language.
11
C OPERATORS
Arithmetic operators Logical operators Bitwise
operators Assignment operators Relational
operators, and Misc operators.
12
DECISION MAKING STATEMENT IN C

• The commonly used decision-making statements are
  given below.
• If statement
• If else statement
• Nested if statement
• Switch statement
• Nested switch statement

13
LOOPS IN C
The loop statements are used to perform the same
task for multiple times. There are various types
of loop statements available in C language
are While loop Do while loop For loop and
Nested loop.
14
C PROGRAMMING FUNCTIONS
A function is a group of statements working
together to perform a particular task. A perfect
function includes some parts such as return
type, function name, parameters, and function
body.

POINTERS IN C
The pointer is a variable that is used to store
the address of another variable. The pointers in
C programming language are easy to learn and
use. Some complex works can be achieved easily
using pointer concept. Moreover, dynamic
allocation is not possible without using pointer
concept. If you want to be a perfect programmer,
it is necessary to learn pointer concept.

C STRUCTURE CONCEPT
The structure is a collection of various data
types. Union Type Typedef In C I/O files In C
19
C PREPROCESSOR DIRECTIVES

• The preprocessor is a text substitution tool
  which is used to provide instructions to the
  compiler to perform required preprocessing
  before starting compilation process. Some of the
  preprocessor directives are define,
• include, undef, ifdef, if, etc.
• Type casting and memory management also add
  advantage to c programming.
