Some immediate disadvantages:
stack using array first not declare stack size and not limited data store in stack.
yes,cursor implementation possible in priority queue.
Stacks are often implemented using the same node structure as a linked list.
Stack is an abstract data type that allows you to input and output data in a way that the first data which was placed in the stack will be the last one to get out. We use physical examples of stack in our daily lives such as the stack of dishes or stack of coins where you only add or remove objects from the top of the stack. You can see the implementation in c++ in related links, below.
in dynamic stack we don't have to initialize the size of array while in static stack we have 2 initialize it ......
O(1)
stack abstract datatype
There is no inherent relationship between the two. It's possible to implement a stack using an array to store date, but that's about it.

Both are linear data structures.
A stack overflow is usually the cause of an array that is too small to be able to hold the intended data. To fix a stack overflow, the array must be locally declared (this means not dynamically allocated off of the heap) and then you must change the amount of "slots" in the array to something that is big enough to hold your data.
You would do this if you implement a stack using an array. Using a zero-based index to keep track of the top of the stack (the end of the array) means we must use the value -1 to indicate an empty stack. This is because an array of n elements will have indices 0 through n-1, where index n-1 represents the element at top of the stack. An empty stack has 0 elements, therefore the top of the stack is represented by index -1.
A stack overflow is a type of buffer overflow in which an array writes memory outside of the array boundaries. The keyword here is "stack". The stack is a section in memory in which local variables and other program data are kept for future reference. When the stack gets overflown, adjacent program memory, such as variables, pointers, etc, will be overwritten and cause your program to crash.
O(1)
A stack can be implemented as an array or a list. If an array, simply push the new element onto the end of the array. If a list, point the new node at the head node then make the new node the new head of the list.
