## Types Of Arrays
There are two types of array based on way, we declare it.
**Note** that arrays in C++ are not permutable in size, which means that once you've declared a array with size 5, it can't be enlarged or made smaller. In case you really need a bigger array with the same entries, you would have to copy all entries to a new array of bigger size. **1**. Static array:
Those arrays whose size is defined before compile time like in the examples above, are called static arrays. In these arrays we can't change their size, once they are declared.
**2**. Dynamic array:
Dynamic arrays are those arrays, whose size is not known at compile time and we can define their size at run time. These arrays are created by using **new** keyword and when done with that array we can delete that array by using the **delete** keyword.
### Access: ### Access:
Elements from an array can be accessed via reference of their position in the array. (Start counting from 0). Elements from an array can be accessed via reference of their position in the array. (Start counting from 0).
