Study Notes
Queue Data Structure
- The code implements a queue data structure using a character array
swith maximum lengthmaxlength. - The
topvariable keeps track of the top element of the queue, initialized to -1. - The
resetfunction sets thetopto -1 to empty the queue. - The
enqueuefunction adds a charactercto the queue, incrementing thetopand storing the character at the newtopposition. - The
dequeuefunction removes and returns the front character of the queue. It shifts all elements down by one position and decrements thetop. - The
emptyfunction checks if the queue is empty by comparing thetopto -1. - The
fullfunction checks if the queue is full by comparing thetoptomaxlength - 1. - The
displayfunction is missing, but it is likely intended to display the contents of the queue.
