1 Data Structures: A Pseudocode Approach with C1 Chapter 4 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 Queues

26 Data Structures: A Pseudocode Approach with C26 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
