Answer 2

Size of our Array is predefined and insertion/deletion operations are a bit difficult.

Explanation:

• The Array can be described as a group of homogenous data types stored with Contiguous memory allocation.
• The size of an array is allocated when the array is created. After Creation, its size is Fixed.
• Arrays store elements in Contiguous memory allocations.
• So for delete and insert operation in Array we need to move the other elements of an array according to the allocated space.

Therefore, The overall size of the array is predefined at the time of compilation and the Insertion/Deletion operation is a bit difficult.
