Idea: Word Count

Create a simple command-line tool that takes a text file as input and outputs the number of words in the file.

Requirements:

1. Input:

   • The tool should take a text file as a command-line argument.

2. Processing:

   • Count the number of words in the file. Consider a word as any sequence of characters separated by whitespace.

3. Output:

   • Display the total number of words in the file.

Example Usage:

# Using the tool in different languages
# Example in Python
python word_count.py input.txt

# Example in JavaScript (Node.js)
node word_count.js input.txt

# Example in Ruby
ruby word_count.rb input.txt

# Example in Go
go run word_count.go input.txt

# Example in C++
./word_count_cpp input.txt

Tips:

• Keep the tool simple, focusing on the core functionality of counting words.
• Consider handling errors, such as when the file does not exist or when there are issues reading the file.
• Write the tool in multiple languages to compare and contrast the implementations.

This project allows you to explore file I/O, command-line argument handling, string manipulation, and basic program structure in different programming languages. It's a great way to gain familiarity with the syntax and features of various languages while working on a practical task.
