• 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, C was developed at Bell Labs
by Dennis Ritchie for the Unix
Operating System (OS) in the early
1970s.

An example of simple program in C:
#include<stdio.h>
void main()
{
printf(“I Love Programmingn”);
printf(“You will Love it too”);
printf(“once you know the trick”);
}

6. Control Statement
A control statement is a statement that
determines whether other statements
will be executed.
• An if statement decides whether to
execute another statement, or decides
which of two statements to execute.
• A loop decides how many times to
execute another statement.

8. Functions
• A function is a group of statements
that together perform a task.
• Every C program has at least
one function, which is main(), and all
the most trivial programs can define
additional functions.
• You can divide up your code into
separate functions.

• An array is a collection of data items,
all of the same type, accessed using a
common name.
• A one-dimensional array is like a list;
A two dimensional array is like a
table;
• The C language places no limits on the
number of dimensions in an array,
though specific implementations may.

Ph. No. :9729666670,4000670 Website: www.batracomputercentre.com
• A string in C is merely an array of
characters. The length of a string is
determined by a terminating null
character: '0' .
• So, a string with the contents, say, "abc"
has four characters: 'a' , 'b' , 'c' , and the
terminating null character.
• The terminating null character has the
value zero.

• A pointer is a variable which contains the
address in memory of another variable.
• We can have a pointer to any variable
type.
• The unary or monadic operator & gives
the ``address of a variable''.
• The indirection or dereference operator *
gives the ``contents of an object pointed
to by apointer''.

• Structure is another user defined data
type available in C that allows to
combine data items of different kinds.
• Structures are used to represent a
record. Suppose you want to keep track
of your books in a library.
• To define a structure, you must use
the struct statement. The struct
statement defines a new data type, with
more than one member.

20. Unions
• A union is a special data type available
in C that allows to store different data
types in the same memory location.
• You can define a union with many
members, but only one member can
contain a value at any given time.
• Unions provide an efficient way of
using the same memory location for
multiple-purpose.
