 ## Why do we need array?
 In computer programming, the most of the cases requires to store the large number of data of similar type. To store such amount of data, we need to define a large number of variables. It would be very difficult to remember names of all the variables while writing the programs. Instead of naming all the variables with a different name, it is better to define an array and store all the elements into it.

 * Elements of the array are stored at contiguous memory locations where the first element is stored at the smallest memory location.
 * Elements of the array can be randomly accessed since we can calculate the address of each element of the array with the given base address and the size of data element.

 You can access elements with the help of the index at which you stored them.
