![ An array is a fixed-size sequential collection
of elements of same data types that share
a common name.
• It is simply a group of data types.
• An array is a derived data type.
• An array is used to represent a list of
numbers, or a list of names.
EXAMPLESOF ARRAYS:-
• List of employees in an organization.
• Test scores of a class of students.
• List of students in the college.
For example, to represent 100
students in college, can be written as
Student [100]
Here students is a array name and [100]
is called index or subscript.](https://image.slidesharecdn.com/pptonarraysinc-200514130805/85/Ppt-on-arrays-in-c-2-320.jpg)
![ A variable which represent the list of items
using only one index (subscript) is called
one-dimensional array.
• For example, if we want to represent a set of
five numbers says ( 20,25,30,35,40) by an
array variable number, then number is
declared as follows,
Int number [5]
• The computer store these number as :
Number[0]
Number[1]
Number[2]
Number[3]
Number[4]
• The values can be assigned to the array as :
Number[20]
Number[25]
Number[30]
Number[35]
Number[40]](https://image.slidesharecdn.com/pptonarraysinc-200514130805/85/Ppt-on-arrays-in-c-4-320.jpg)
![ A variable which represent the
list of items using two index
(subscript) is called two-
dimensional array.
• In two-dimensional arrays, the
data is stored in rows and columns
format.
• The general form of two-
dimensional array ;
Array-name [row_size][column_size]
Example :- int table[2][3]=
{0,0,0,1,1,1};
Here the element of first row
initializes to zero and the elements of
second row initializes to one.
• This above statement can be
written as :
Int table[2][3] = [{0,0,0},{1,1,1}]](https://image.slidesharecdn.com/pptonarraysinc-200514130805/85/Ppt-on-arrays-in-c-5-320.jpg)
![ A variable which represent the
list of items using more than
two index (subscript) is called
multi-dimensional array.
• The general form of multi
dimensional array is:
type array-name[𝒔 𝟏][𝒔 𝟐][𝒔 𝟑]……[𝒔 𝒏]
• Where S is the size; for ex-
Int survey[3][5][6]
Float table[5][4][5][3]
• Here survey is a three-
dimensional array and table is a
four-dimensional array.](https://image.slidesharecdn.com/pptonarraysinc-200514130805/85/Ppt-on-arrays-in-c-6-320.jpg)
