Code review for CMP1903M Resit Assessment

[jesse1234-cyber]

1. Naming
   Strength: Code has some recognizable variable names like wordcounts and file Path.
   Issues:
   Variable names like s, t, and w are vague and not self-explanatory.
   Suggestions:
   Rename variables for better readability:
   s → cleaned Line
   t → words
   w → word
   lines → file Lines

2. Code Structure
   Strength: Code logic is clear and performs as expected.
   Issues:
   Entire logic is inside the Main() method, which reduces modularity.
   Suggestions:
   Break the program into reusable methods like:
   Read File(string file Path)
   Process Lines(string[] lines)
   Display Wordcounts(Dictionary<string, int> wordcounts)

3. Error Handling
   Strength: Basic file existence check using File.Exists().
   Issues:
   No exception handling for ReadiLine() or unexpected errors.
   Suggestions:
   Add messages to guide the user if the file path is invalid or empty.

4. File Assumptions
   Issues:
   Assumes file exists and has valid content.
   Doesn’t check if lines are empty or if file is unreadable.
   Suggestions:
   Add user feedback for such conditions.

5. OOP Principles
   Issues:
   Entire logic is in a single class with one method.
   Lacks encapsulation and separation of concerns.
   Suggestions:
   Apply basic OOP structure:
   class FileProcessor { string[] ReadFile(); }
   class WordAnalyzer { Dictionary<string,int> CountWords(); }
   class DisplayHelper { void ShowResults(); }
   This helps maintain, test, and extend the program.

6. Output
   Strength: Output uses Console.WriteLine() for user interaction.
   Issues:
   Not formatted or sorted, making results harder to read.
   Suggestions:
   Display results alphabetically or by frequency.
   Use clear headings like: --- Word Frequency Results ---.

7. Program Logic
   Strength: Functional and loops through lines correctly.
   Issues:
   Logic for punctuation removal and splitting is correct but could use comments.
   Suggestions:
   Add comments above critical logic blocks.
