Without using C++ queue STL, write a simple menu based selection to insert, delete, show and exit from queue.

1. Create a class called Queue with member variable queueArr as integer queue array, integer rear and integer front to keep track both rear and front element in the queue array.
2. Define several member functions in Queue such as:
 a)  constructor – initialize both rear and front to -1
 b)  insert – receive an integer and check if queue is full, if not then insert           the integer to the queue array
 c)  delete – delete front element from queue if front is not equal to rear            (empty)
d)   display – if rear is not equal to front, then print out the queue array.

3. Write a main function to test the Queue class.
