   An arrayis 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.

   A variablewhich 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]

   A variablewhich 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}]

   A variablewhich 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.

  • Using pointersfor accessing arrays. • Passing arrays as function parameters. • Arrays as members of structures. • Using structure types data as array elements. • Arrays as dynamic data structures. • Manipulating character arrays and strings.
