ECE-206 HW-10A: C++ Text File Write And Count

ECE-206 HW-10A: C++ - Text File Write a C++ program to count the number of consonants and vowels in a text file

Write a C++ program to count the number of consonants and vowels in a text file. The program must be able to handle consonants and vowels of upper and lower cases. Include a detailed comment header and comment statements. For example: The following two lines of sentences have 47 consonants and 29 vowels. Maxim 1: Programming is an art! Maxim 2: While there are many ways to Rome, you just need to find them. Test your program with a text file that contains the two sentences in the example. Run Output Consonants: 47 Vowels: 29 Submit a copy of the working and well-documented program, and run output.

Paper For Above instruction

The task is to develop a C++ program that reads a text file, counts the number of vowels and consonants regardless of their case, and displays the counts. This project emphasizes file handling, character processing, and careful documentation within the code. Proper comments and a detailed header are essential to clarify the program’s logic and functionality.

To begin, the program must open a specified text file for reading. It should handle potential errors gracefully, such as the file not existing or being inaccessible, by providing appropriate error messages. The core logic involves reading each character from the file, determining whether it is a vowel or a consonant, and incrementing the respective counters. The program needs to consider both uppercase and lowercase vowels ('A', 'E', 'I', 'O', 'U' and their lowercase counterparts) and consonants (all alphabetic characters that are not vowels). Non-alphabetic characters such as digits, punctuation, and whitespace should be ignored in the count.

The implementation involves a loop that reads characters until reaching the end of the file, updating counters as characters are classified. After processing, the program outputs the total counts of vowels and consonants, which can then be compared with the example case for verification. For example, given the sentences: "Programming is an art!" and "While there are many ways to Rome, you just need to find them," the total counts—47 consonants and 29 vowels—must be reflected in the output.

Documenting is critical: the code must include a meaningful comment header explaining the purpose, inputs, and outputs. Additionally, inline comments should clarify key steps, such as character classification, case conversion, and file handling. The code should follow good programming practices, including proper indentation and variable naming, ensuring readability and maintainability.

Implementation outline:

  • Include necessary headers: <iostream>, <fstream>, <cctype> for character functions.
  • Create a function to determine if a character is a vowel.
  • Open the text file using an ifstream object and handle errors if the file cannot be opened.
  • Read characters until EOF, classify and count vowels and consonants.
  • Display results after processing.
  • Submit the source code and a sample output.

By following these steps, the program effectively counts vowels and consonants from any input text file, demonstrating fundamental file I/O, character processing, and debugging skills in C++.
