Program Plan Intro

Member functions in stack template adapter class:

The member functions in stack templates are given below:

• “s.size()”:
  • This function is used to returns the number of elements in the stack.
  • “s” is object of stack template adapter class.
• “s.empty()”:
  • This function is used to returns “true” if the stack is empty.
  • Otherwise, this function returns “false”.
• “s.top()”:
  • This function is used to returns top value of the given stack.
•  “s.push(Value)”:
  • This function is used to insert a “Value” to the top of stack.
•  “s.pop()”:
  • This function is used to removes the top value of the stack.
  • In stack, the “pop” function is a void function.
    • So, it does not return the removed value.
• “st1 == st2”:
  • This function is used to check whether the
    two stacks are equal or not.
  • If “st1.size == st2.size”, then returns “true”. That is if the number of elements in stack “st1” is equal to corresponding elements in stack “st2”.
  • Otherwise, returns “false”.
