This project demonstrates the implementation of the Singleton design pattern with lazy initialization in C++. The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance.

• Lazy Initialization: The Singleton instance is created only when it is first requested.
• Thread Safety: The implementation is thread-safe to guarantee correct behavior in multi-threaded environments.
• Expensive Task Simulation: Includes a method expensiveTask() to simulate an expensive operation, showcasing real-world usage scenarios.
• Error Handling: Proper error handling is implemented to handle invalid arguments and other exceptional situations.

• This project requires C++20 to compile and run successfully.

This project is tested and compatible with the following compilers:

• Mingw g++
• Microsoft Visual C++ (MSVC)

To use the Singleton pattern in your project, follow these steps:

1. Include the SingleTon.h header file in your project.
2. Use the getInstance() method to obtain the Singleton instance.
3. Call the desired methods or perform operations on the Singleton object.

#include "SingleTon.h"

int main() {
    // Obtain the Singleton instance
    SingleTon* singleton = SingleTon::getInstance();

    // Use the Singleton instance
    singleton->expensiveTask(42);

    return 0;
}
