  1. Chapter 4 Queues Objectives • Upon completion you will be able to: • Explain the design, use, and operation of a queue • Implement a queue using a linked list structure • Understand the operation of the queue ADT • Write application programs using the queue ADT • Explain categorizing data and queue simulation Data Structures: A Pseudocode Approach with C

  2. Data Structures: A Pseudocode Approach with C

  3. 4-1 Queue Operations • This section discusses the four basic queue operations. Using diagrammatic figures, it shows how each of them work. It concludes with a comprehensive example that demonstrates each operation. • Enqueue • Dequeue • Queue Front • Queue Rear • Queue Example Data Structures: A Pseudocode Approach with C

  26. 4-3 Queue ADT This section develops the data structures and C code to implement a Queue ADT. The first program contains the data structure declarations and a list of the prototypes for all of the functions. We then develop the C code for the algorithms discussed in Section 4.2 • Queue Structure • Queue ADT Algorithms Data Structures: A Pseudocode Approach with C
