What data type should all the elements in an array be?

What is an Array?

Array : Array is an collection of similar type of data referenced under the same name. It is a linear data structure. indexing of an Array starts from 0 and ends on (n - 1) .where n=size of an Array. Each element can be accessed directly  by only using its index. 

We declare an Array as Syntax: Data type array_name[ size of an array];

The data type should be same for all the elements in an array. example : int ,float ,string ,char etc. for example the data type of an Array is float then it can only store the float values.

If we declare an Array of size 5 of float type . It can be written as 

 float a[ 5 ]; //here a is the name of an Array . 

indexing will be start from 0 and ends on 4 .

the elements of an Array is as shown.

a[0]=4.5;

a[1]=2.0;

a[2]=1.1;

a[3]=7.8;

a[4]=8.8;

 As per above example  we can only store the float value if we declare an Array as float data type.  we can't add a int value or char value . we can store only the values , which declared as data type. 

Let's understand with one more example:

We  declare an Array of String data type . String is an collection of character closed under the double quotes . It takes one extra byte. It can be written as ,

String  name[5]; // here name is the name of an Array .

Indexing will be start from 0 and ends on 4 .

The elements of an Array is as shown.

name[0]="Samir";

name[1]="Sumit";

name[2]="Rekha";

name[3]="Raj";

name[4]="Ram";

We can only store the String value , if we declare an Array as String  data type.  we can't add a int value or char value . we can store only the values , which declared as data type. 

What about char data type ? what  happened when we select the data type as char . Let's Understand.

We  declare an Array of char  data type . character closed under the single  quotes . It takes one  byte. It can be written as ,

Char alphabet[5]; // here alphabet is the  name of an Array .

Indexing will be start from 0 and ends on 4 .

The elements of an Array is as shown.

name[0]='s';

name[1]='u';

name[2]='e';

name[3]='a';

name[4]='m';

We can only store the char value , if we declare an Array as char  data type.  we can't add a int value or String  value . we can store only the values , which declared as data type. 

As we see above all the three example , it confirmed that the same data type should all elements in an array have.
