Program Plan Intro

Stack:

A stack is type of container. It performs “Last In First Out”.

  • In stack, the item which is inserted at last will be retrieved first.
  • A stack can perform two operations. They are:
    • Push – Inserting an element inside a stack.
      • When the first element is pushed into the stack, the element will be at the “top” the stack. When the second element is added, the first element is pushed down and the second element will be at the top position, like this it goes on until the element which pushed at last will be at the top of the stack.
    • Pop – Deleting an element from the stack.
      • The element which is inserted at last will be deleted first.
  • The elements can be inserted and retrieved at any one end of the stack.

Suppose the following operations were performed on an empty stack:pus h(8);pus h(?);pop();push (19);pus h(21);pop();Insert numbers in the following diagram to show what will be stored in the staticstack after the operations have executed
TRUE or FALSE? Please answer the following question and state the reason why: Thank you! In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null. STL empty function will yield a value of true if the stack has elements.
TRUE or FALSE? Answer the following question and state the reason why: In a dynamic stack, the node that was popped is deleted. In a dynamic stack, the pointer top stays at the head after push operation. STL function top returns a reference to element at the top of the stack. STL empty function will yield a value of true if the stack has elements.
