C Programs Based on Queue

Algorithm 1Write an algorithm for inserting an element in to the queue using array
Solution:
    Let Q be the array of specified size, SIZE

1. Initialize front=0,rear=-1
2. Input the value to be inserted and assign to variable "data"
3. If (rear > = SIZE)
         (a) Display "Queue Overflow"
         (b) Exit.
4. Else
         (a) rear=rear+1;
5. Q[rear]=data;
6. Exit

Algorithm 2: Write an algorithm for deleting an element from the queue using array
Solution
    Let Q be the array of specified size,SIZE

1. if (rear < front )
       (a) front=0,rear=-1
       (b) Display "The queue is empty"
       (c) Exit
2. else
       (a) Data=Q[front]
       (b) front=front+1;
3. Exit
