Modern C++ generally refers to C++ code that utilizes features and best practices introduced in C++11 and later standards (C++14, C++17, C++20, and upcoming C++23)

<h4>
Basic Singleton Implementation
</h4>
<p>
Here's a straightforward implementation of a Singleton in C++ that uses the Meyers' Singleton approach:
</p>

<pre style="font-size:90%">
<code class="language-cpp line-numbers normalize-whitespace">
class Singleton {
public:
    // Delete copy constructor and assignment operator
    Singleton(const Singleton&) = delete;
    Singleton& operator=(const Singleton&) = delete;

    // Static method to get the instance of the Singleton class
    static Singleton& getInstance() {
        static Singleton instance; 
        return instance;
    }
    void mainTask() {
        // ...
    }
private:
    // Private constructor to prevent direct instantiation
    Singleton() {}
};
</code>
