Write a modular program to do the following:

  • Ask the user for a file to read.
  • Read through that file and count all the occurrences of each word that is found.
  • Output this list of words (along with their counts) to the screen.

At a minimum, there should be:

  • A vector to store the words and another vector to keep track of how often each word occurs; these are parallel vectors, where the index corresponds between a word and its count.
  • A main() function that controls the operation of the program.
  • A findWordPosition() function that takes a vector and a string as parameters and returns the position that the string occupies in the vector, or -1 if not found. Word comparison should ignore case.
  • An addWord() function that takes a string and two vectors, storing the new word in the vector and setting its count to 1.
  • A reportToScreen() function that takes the two vectors and displays three columns: the words and their number of occurrences, aligned for readability.

Note: To ensure proper alignment, consider calculating the maximum length of any word when formatting the output.

This program is designed to analyze a text document by counting the frequency of each word present within the file. Its objective is to process the input file, tally each unique word regardless of case, and then display the results in a clear, tabulated format. The approach emphasizes modularity, clarity, and efficiency, employing a set of well-defined functions to facilitate ease of understanding, testing, and maintenance.

The core of the program involves reading a user-specified file, parsing its contents into individual words, and updating parallel vectors that store the words and their respective counts. The use of vectors allows dynamic management of the dataset since the total number of unique words is unknown beforehand. This flexibility is essential for processing files of arbitrary size and vocabulary.

The main function orchestrates the overall flow, prompting the user for input, processing the file, and then calling sub-functions to handle specific tasks such as finding the position of a word, adding new words, and reporting the results. The findWordPosition() function searches for a word in the vector, ignoring case differences, returning its position or -1 if absent. When a new word is discovered, the addWord() function inserts it into the vectors, initializing its count to one.

The reportToScreen() function presents the results in a neatly formatted output with aligned columns. It calculates the maximum length of any word to ensure proper alignment across all entries, enhancing readability. This comprehensive display provides a clear overview of the vocabulary and their frequencies within the analyzed file.

Coding best practices, such as adequate commenting and proper indentation, are adhered to throughout the implementation to facilitate easy comprehension and future modifications. This code can serve both educational purposes and practical text analysis needs, providing a foundation for more advanced text processing tasks.

Overall, this program offers an effective solution for text analysis, combining file input handling, string processing, and dynamic data management, all wrapped within a modular, maintainable structure.
