STACK follows LIFO. Thus the item that is first enetered would be the last removed.

In array the items can be entered or removed in any order. Basically each member access is done using index. No strict order is to be followed here to remove a particular element.

Array is a linear Data Structure in which insertion and deletion can take place in any position.  The elements can be retrieved randomly in Arrays.

Stack is also a linear data structure in which insertion and deletion will take place at the top position alone. It follows LIFO order i.e. last in first out. The element in the top most position alone can be retrieved.

Arrays : stored in random orderStack: stored in LIFO order.

All the above comments are true but I want to add to it is that the size of array is fixed while in a stack its not fixed.It something like dynamic allocation.Its size can grow and shrink.

Basic Difference is that the size of array is fixed while stack size can grow and shrink.Stack is a dynamic concept

We can create stack and array as dynamic and also static

Conceptual wise both are different. I think comparison is not possible. But to my knowledge size if local array is declared then it stores in stack. Here size of an array should be fixed before compile time. But in stack all operation related to local variables takes place. Stack can be shrink or grow.

Can you explain why both are static?

To my understanding both array and stacks are data structures used in storage of data, but a stack is a method of implementing the way data is stored and manipulated in Array.

Array and stack both data structure and also store same type data. but stack have some property i.e PUSH, POP etc.
Array is static But When Stack creates using Array then it is static and when Stack creates using Link list then it is Dynamic. so stack is static or dynamic but array always static.

In an array, you have a list of elements and you can access any of them at any time. (Think of a bunch of wooden blocks all laid out in a row.)
But in a stack, theres no random-access operation; there are only Push, Peek and Pop, all of which deal exclusively with the element on the top of the stack.

Main difference is in access. With stack we can not access values randomly but with array we can access any item any time.
