1. Recursive and iterative function implementation and comparison for solving mathematical problems with parameterized function calls and testing outputs.

2. Object-oriented programming tasks, including designing a `Picture` class, private attribute handling, constructors, getter and setter methods, file reading, and user-defined searches with flexible input handling.

3. Ordered binary tree implementation using a 2D array, including array initialization, adding nodes, pointer updates, and data printing in traversal order.

4. Binary tree traversals using in-order algorithms with recursion to visit left nodes, roots, and right nodes, alongside testing with predefined data.

5. Data structure management through efficient handling of arrays for object storage, text file integration, exception handling, and search functionality in main programs.

6. Practical programming scenarios using high-level languages like Python, Java, or Visual Basic for modular programming, debugging, and evidence documentation.
