Explain the Differences Between `volatile`, `mutable`, and `const` Keywords in C++
The `volatile`, `mutable`, and `const` keywords serve different purposes in C++. `volatile` prevents the compiler from optimizing a variable, as its value may change at any time. `mutable` […]

How Do You Implement a Lock-Free Data Structure in C++?
Lock-free data structures allow concurrent access without using locks. They use atomic operations to ensure thread safety. Such structures, like lock-free stacks and queues, improve performance by avoiding […]

What Are the Implications of the ‘Rule of Five’ in C++11 and Later?
The ‘Rule of Five’ in C++11 and later states that if a class defines one special member function, it should define all five. These functions are the destructor, […]

What Are the Main Differences Between the Different C++ Smart Pointers (`unique_ptr`, `shared_ptr`, `weak_ptr`)?
C++ offers three main smart pointers: `unique_ptr`, `shared_ptr`, and `weak_ptr`. `unique_ptr` provides exclusive ownership and cannot be copied. `shared_ptr` allows multiple owners with reference counting. `weak_ptr` is used […]
