Just think, one day your teacher give you a box of different
types chocolate, and tell you there are 10 types of chocolate you count only
how much each type of chocolate , and put those numbers in your program and
determine sum of them.
What you will do? You able to count all chocolate number and
store them in different variable. At least 10 variable need to store them. Do you know
you can store them into one variable? The
method of this name is array.
Array is the method of store one kinds of data into one variable.

0 1 2 3 4 5 6 7 8 9
Here are ten boxes which contain ten same type of data. We give number of those box for specification their position . so 0 no index contain 5, 1 no index contain 7……..
If we write them as chocolate[0]=5, chocolate[1]=7, chocolate[2]=5, chocolate[3]=2,… … . . so chocolate
variable store all of those item, its called array.
An array is the collection of one kinds of data. In a array we can store one type of data. An
integer type array we can store integer type data , an character type array we
can store character type of data.
For use an array first need to initialize an array with
length. Length is the capacity of array. How much data can store an array its
called the capacity of the array.
Int chocolate[10];
Here int is the data type of chocolate array and 10 is the capacity of this array.
chocolate [0]=5, chocolate[1]=7,
chocolate[2]=5, chocolate[3]=2,… … . .
when we use array the position of array length we use index
number of array. here 0,1,2,3... are index number.index number of array start from 0.
