Word Counter: Tabulating Basic Document Statistics

Pa 1 Word Countertabulating Basic Document Statistics Is An Interest

Write a C++ program that prompts the user for an input file and an output file. The program reads each line of the input file, adds a line number at the beginning of the line, and writes it to the output file. Additionally, the program calculates and displays the number of paragraphs, lines, words, and characters (both including and excluding spaces). A paragraph is defined as a line containing only a newline character ("\n"). After processing the entire file, the program outputs a summary of these statistics at the bottom of the output file.

The program must include the following functions:

• int get_character_count_with_spaces(string line); — Returns the total number of characters in the line, including spaces, excluding newline characters.
• int get_character_count_without_spaces(string line); — Returns the total number of characters excluding spaces and newline characters.
• int get_words(string line); — Returns the number of words in the line, where words are separated by spaces.
• int is_paragraph(string line); — Returns 1 if the line contains only a newline character, otherwise 0.
• void parse_file(ifstream input_file, ofstream output_file); — Reads the input file, processes each line, and writes the modified lines along with the statistics to the output file.

Your program should follow a style guide, include an appropriate header comment with your details, and utilize all the specified functions. The output format must match the sample provided. Also, include a 350-word reflection essay discussing your experience with the assignment, highlighting challenges faced, insights gained, or suggestions for future improvements.

The task of developing a C++ program to count basic document statistics and modify file contents presents a multifaceted challenge that develops both programming skills and conceptual understanding. This assignment emphasizes the manipulation of file input/output streams, string processing, and modular function design, all of which are fundamental to robust software development.

Developing the core functions—such as counting characters with and without spaces, counting words, and identifying paragraphs—requires a detailed understanding of string operations. For example, the functions for character counting must accurately exclude newline characters, which can be tricky when dealing with strings read line-by-line. Similarly, counting words necessitates a reliable method for tokenizing strings based on spaces, considering multiple spaces or leading/trailing spaces, which may affect word counts.

The paragraph detection method, which considers lines containing only a newline character as paragraphs, underscores the importance of precise string comparison and control flow logic. Ensuring that paragraph counting is accurate involves careful handling of line reading and comparison operations. Meanwhile, the overall file parsing process consolidates these individual functions into an integrated workflow, demonstrating effective use of modular programming and control structures.

Implementing the line numbering feature requires a structured approach to file reading and writing, integrating line counters with output formatting. Writing the modified lines with line numbers at the beginning aligns with good file manipulation practices, providing clear output that enhances readability. The inclusion of a final summary section, detailing the counts of paragraphs, words, and characters, consolidates the program's functionality as a comprehensive analysis tool for textual documents.

Throughout this project, one of the most significant challenges was ensuring accurate and efficient string processing, especially in counting characters and words while excluding certain characters. Debugging and testing with different input files exposed edge cases such as empty lines or lines with multiple spaces, reinforcing the importance of thorough validation. Comparing counts with sample outputs and tolerating a 10% variance in results provided a realistic framework for development and testing.

Reflecting on this experience reveals valuable insights into modular programming and string manipulation. Structuring the program with dedicated functions promotes code readability and reusability, while testing highlights the importance of handling various input scenarios robustly. Future improvements might include more sophisticated word boundary detection that accounts for punctuation or different whitespace characters, as well as adding command-line argument support for flexible file handling.

Overall, this assignment not only enhances practical coding skills but also deepens understanding of text processing techniques vital in many real-world applications such as text analytics, document editing, and data extraction. The iterative development process, coupled with testing and reflection, underscores the importance of careful planning and adaptability in software development.
