🚀 clsString – Lightweight C++ String Utility Library

clsString is a comprehensive C++ class designed to simplify string manipulation. It provides a robust set of functions for common text-processing tasks, serving as an excellent demonstration of Object-Oriented Programming (OOP) and manual logic implementation.

---

🛠 What This Library Provides

The library offers a wide range of functionalities organized for ease of use:

• String Analysis: Get length, count words/characters, and perform vowel analysis.
• String Formatting: Change case (Upper/Lower), capitalize words, or invert cases.
• String Cleaning: Advanced trimming (Left, Right, Both) and punctuation removal.
• Text Manipulation: Split, Join, Replace, and Word Reversal logic.

🔄 Dual-Usage Model

1. Static Methods: For direct, stateless one-off operations.
2. Instance Objects: To store a string internally and apply multiple sequential transformations.

📊 Feature Matrix

Category	Key Methods
Parsing	Split, Join, CountWords, ReversString
Formatting	UpperAllLattersOfString, LowerAllLattersOfString, InvertAllLettersCaseOfString, UpperFirstLatterOfEachWord

🎯 Project Purpose

The main goal of this project is hands-on practice and demonstrating the ability to:

• Write clean and organized C++ code.
• Apply core OOP concepts like Encapsulation and Methods.
• Implement complex string-processing logic manually to sharpen problem-solving skills.
• Gain practical experience with std::string and std::vector.

Note: This project is a practical exercise for educational purposes, not a replacement for standard C++ libraries.

💻 Example Usage

1️⃣ Object-Oriented Approach (Instance)

This approach is best when you want to perform multiple transformations on the same string instance.

// Create an object with an initial value
clsString text("  !!hello world  ");

// Chain transformations sequentially
text.RemovePunctuations();
text.TrimForString();
text.UpperFirstLatterOfEachWord();

cout << text.Value(); // Output: Hello World

2️⃣ Static Utility Approach (Stateless)

Use this for quick, one-off operations without creating an object.

// Get the first word of a sentence directly using a static method
string result = clsString::Split("Backend.NET.Developer", ".")[0]; 

cout << result; // Output: Backend

📝 Important Notes

• Educational Focus: Some functions include std::cout outputs for demonstration and debugging.
• Clarity Over Performance: The implementation prioritizes code readability and logical flow over micro-optimizations.
