Data Structures and Interfaces

Why Use Arrays to Store Data?  

- Improves program readability.  

- Enables efficient searching with loops.  

- Simplifies code modifications.  

Linked Lists vs Arrays  

Advantages of Linked Lists:  

- Easier to add and remove data dynamically.  

- Maintains data order using pointers.  

Disadvantages of Linked Lists: 

- Requires extra storage for pointers.  

- Increases code complexity.  

Procedure Interfaces  

- Allow data transfer within a program.  

- Define parameters for functions.  

- Specify parameter types and order.  

Benefits of Using an Array of Records  

- Reduces the number of identifiers needed.  

- Simplifies program development.  

- Supports iteration for efficient searching.  

- Enables direct access using array indices.  

Differentiating Parts of a Message in a File  

- Use special characters as separators.  

Drawbacks of This Approach:  

- Increases file size.  

- Makes storage and retrieval algorithms more complex.
