What are the main features of the stack?

The main feature of the stack is last-in-first-out. The stack is a linear list with limited operations, which limits insertion and deletion operations only to the end of the list. All insertion and deletion operations on the stack are performed at the top of the stack, while insertion and deletion are not allowed at the bottom of the stack.

Related introduction:

Stack (stack), also known as stack, is a kind of limited operation linear table. A linear table that restricts insertion and deletion operations only to the end of the table. This end is called the top of the stack, and the other end is called the bottom. Inserting a new element into a stack is also called pushing, pushing or pushing. It is to put the new element on top of the top element of the stack, making it a new top element; deleting elements from a stack is also called popping or pushing. Pop off the stack, which deletes the top element of the stack and makes its adjacent elements the new top element of the stack.

The stack is a linear list where insertion and deletion operations are performed at one end of the list. All insertions and deletions of the stack are performed at the top of the stack, while insertions and deletions are not allowed at the bottom of the stack.
