1. Declaration and initialization of global variables and arrays for data storage in practical programming scenarios.
2. Implementation of the `Initialise()` procedure for input validation and storage in arrays.
3. Application of sorting algorithms like `BubbleSort()` to arrange data in ascending order.
4. Use of iterative binary search to locate data elements within sorted arrays, including error handling for unsuccessful searches.
5. Development of object-oriented programs, including class definitions, constructors, and accessor methods, to manage structured data.
6. Reading and processing file data into objects, validating input, and storing objects in arrays.
7. Queue data structure implementation using `Enqueue()` and `Dequeue()` functions, including validation and error handling.
8. Calculation and validation of check digits for formatted data entries using predefined algorithms.
9. Combining procedures and functions in the main program to demonstrate functionality, with input/output testing for validation.
10. Usage of exception handling and object-oriented programming to enhance program robustness and efficiency.
