Chapter 13, Problem 8PP

Program Plan Intro

Creation of program to simulate customer arrivals at motor vehicles department

Program Plan:

• Define a class “Queue” to denote methods and operations required for queue.
  • Declare variables that are required for program.
  • Define a constructor “Queue()” and assign values.
  • Define a method “Enqueue()” to insert values into a queue.
  • Define a method “Dequeue()” to remove value from a queue.
  • Define a method “Front()” to return front element of queue.
  • Define a method “Size()” to return size of queue.
  • Define a method “isEmpty()” to check whether queue is empty or not.
  • Define a main method
    • Call method “Enqueue()” to insert values into a queue.
    • Call method “Dequeue()” to remove value from a queue.
    • Call method “Front()” to return front element of queue.
    • Call method “Size()” to return size of queue.
    • Call method “isEmpty()” to check whether queue is empty or not.
    • Loop until the user needs to compute result.
    • To simulate customer arrival call “Enqueue()” method with required parameters.
    • To help next customer call “Dequeue()” method.
