Understanding the Assignment Requirements
Read the Instructions Carefully
The first step in any programming assignment is to thoroughly read the instructions. Pay attention to the specific tasks you are required to complete, the expected inputs and outputs, and any particular constraints or requirements. For instance, in the given assignment, you need to extend a C++ program to handle more complex expressions and modify existing grammar rules. Ensure you understand the scope and details of the project before proceeding.
Analyze the Provided Skeleton Code
If the assignment includes skeleton code, as in the example, start by examining it closely. Understand the structure of the code, the existing functionality, and how it processes input. The skeleton code serves as a foundation, providing a context for the modifications you need to make. Identify the parts of the code that relate to the tasks outlined in the instructions.
Breaking Down the Problem
Identify Core Components
Breaking the assignment into smaller, manageable tasks is crucial for managing complexity. For the provided assignment, you can categorize the tasks as follows:
- Parsing and extending the grammar.
- Handling new operators and expressions.
- Modifying variable and literal tokens.
- Implementing error handling and additional checks.
By breaking the problem down, you can tackle each component separately, making the overall task less overwhelming.
Create a Plan
Outline a step-by-step approach to implement each component. This plan will serve as your roadmap throughout the assignment. A detailed plan helps you stay organized and focused, ensuring that you address all the requirements systematically.
Implementing the Solution
Extend the Grammar
The first significant task is to modify the existing grammar to accommodate the new expression types and operators. Update the parsing logic to handle these changes. This may involve:
- Updating the Parsing Functions: Modify the parsing functions to recognize new operators and expression types. Ensure that the parser correctly interprets the extended grammar rules.
- Extending the Grammar Rules: Update the grammar rules to include unary, binary, ternary, and quaternary expressions. Ensure that the grammar accurately represents the new language constructs.
Update the Token Definitions
Adjust the token definitions for variables and literals to support underscores and floating-point numbers. Modify the lexer or tokenizer to recognize these new patterns. This step involves:
- Modifying the Regular Expressions: Update the regular expressions that define variable and literal tokens to include the new syntax rules.
- Adjusting the Lexer: Ensure that the lexer correctly identifies and categorizes the updated tokens.
Implement New Operators
Define the semantics of the new operators in your evaluation logic. Ensure that the program correctly handles operations like multiplication, division, exponentiation, and custom operators like minimum, maximum, and average. This step involves:
- Adding New Operator Functions: Implement functions to handle the new binary, ternary, and quaternary operators. Ensure that each operator performs the correct calculation.
- Integrating the Operators into the Evaluation Logic: Update the expression evaluation logic to include the new operators. Ensure that the program correctly processes and evaluates expressions containing the new operators.
Modify the Symbol Table
Ensure that the symbol table is re-initialized before each statement is evaluated. This prevents variables from retaining values from previous statements. Implement checks for uninitialized variables and duplicate assignments within a statement. This step involves:
- Re-initializing the Symbol Table: Ensure that the symbol table is cleared before evaluating each new statement.
- Implementing Error Checks: Add logic to detect and report errors for uninitialized variables and duplicate assignments. Create custom exception classes to handle these errors.
Testing and Validation
Develop a Test Plan
Create a comprehensive test plan that covers all new functionalities and edge cases. Include test cases for each new operator and expression type, as well as scenarios involving uninitialized variables and duplicate assignments. This step involves:
- Designing Test Cases: Create test cases that cover all possible scenarios, including normal cases, edge cases, and error conditions.
- Documenting Expected Outcomes: For each test case, document the expected output. This helps you verify the correctness of your program during testing.
Run Tests
Execute the test cases and validate the output against the expected results. Document the test cases and their outcomes in a separate Word or PDF file as required. This step involves:
- Running the Tests: Execute the test cases using your implemented program. Ensure that the program produces the expected results for each test case.
- Recording the Results: Document the actual output for each test case and compare it to the expected results. Note any discrepancies and investigate their causes.
Debug and Refine
Debug any issues that arise during testing. Refine your code to handle edge cases and ensure robust performance. This step involves:
- Identifying Bugs: Use debugging tools and techniques to identify the source of any issues discovered during testing.
- Fixing Bugs: Correct any errors in the code and re-test to ensure that the issues have been resolved.
- Optimizing the Code: Refine the code to improve performance and readability. Ensure that the program is efficient and maintainable.
Documentation and Submission
Document Your Approach
Write a detailed discussion on how you approached the project. Explain your thought process, the challenges you faced, and how you overcame them. This helps in demonstrating your problem-solving skills and understanding of the assignment. This step involves:
- Writing the Approach Document: Describe your overall approach to the assignment, including the planning, implementation, and testing phases.
- Highlighting Key Challenges: Discuss any significant challenges you encountered and how you addressed them.
- Reflecting on the Experience: Reflect on what you learned from the project and any improvements you would make in the future.
Prepare Deliverables
Organize your source code files into a .zip archive. Ensure all files have appropriate headers with your name, date, project details, and file descriptions. Include the test plan document with test cases and their results. This step involves:
- Creating the .zip Archive: Collect all source code files, including headers and implementation files, and compress them into a .zip archive.
- Adding Headers to Files: Ensure that each file contains a header with your name, the date, project details, and a brief description of the file’s contents.
- Including Documentation: Include the approach document and test plan in the .zip archive. Ensure that all required documentation is complete and well-organized.
