1. Programming Constructs and Data Types | Identifying selection, iteration, and subroutine usage in pseudocode; evaluating logical expressions; determining appropriate data types. 2. Summing Positive Integers Algorithm | Writing pseudocode to input 100 integers, summing only positive values, and outputting the final sum. 3. Linked List Implementation | Initializing a linked list using a 1D array, managing null pointers, assigning node pointers sequentially, and outputting data in list order. 4. Grade Boundary Processing | Implementing an algorithm to check if a given exam mark is within 2 marks of a grade boundary; optimizing with a boolean lookup array. 5. Game Character Data Management | Using structured records to store player attributes, implementing a function to count and sum skill levels for specific roles. 6. File Handling and Data Persistence | Writing pseudocode to restore saved game data from a file, extracting structured records, and ensuring game continuity across multiple sessions.
