Yes, a destructor can be virtual in C++, and it should be virtual in a base class if you expect polymorphic behavior (i.e., if the class is meant to be inherited and deleted via a base class pointer). Why? If a base class destructor is not virtual, and you delete a derived class object through […]

Discover a generic, thread-safe map class in C++ that’s production-ready and handles any data type. Unlike std::map, which is not thread-safe by default, this class ensures safe concurrent access in multi-threaded environments. Why Use This?This thread-safe map class offers robust protection against concurrent access issues, unlike the default std::map, which isn’t thread-safe. Its generic design […]

In large C++ projects, using the final keyword for classes can significantly improve stability, maintainability, and encapsulation. This quick guide outlines various scenarios where marking classes as final is beneficial. Derived Classes It’s well known that if a derived class is not intended to be subclassed, you should make it final. However, there are many […]

Hi, in this article I will show you why thread synchronization is required in C++ program.  You will understand the concepts clearly by observing the behaviour of a program WITHOUT and WITH thread synchronization. [Intent of this article is to understand the effect of thread synchronization, not about each statement of the program.] In short: […]

Systems Programming C++ excels in the realm of systems programming, where direct interaction with hardware and low-level operations is a must. Operating systems like Windows and Linux kernel development […]

std::unique_ptr in C++ is a smart pointer in that provides automatic memory management for dynamically allocated objects. It is part of the C++11 standard and helps manage the lifetime of dynamically allocated resources. Key properties of Unique_ptr: unique_ptr  Example: Highlights: Passing unique_ptr in C++ to a function Here’s 2 points to note: Passing by value: […]

Explore actual meaning of type safety in C++ , and if C++ is 100% type safe. You’ll also learn best practices to ensure type safety that will help you write robust code. What is type safety in C++ Type safety in C++ refers to the practice of ensuring that operations and manipulations are performed on […]

We will discuss the capture in Lambda Function in C++ in detail, covering capture by value, reference, pointers, and functions pointer with code examples. You will gain a comprehensive understanding of variable capture within lambda functions, exploring various scenarios through clear examples. Capture in Lambda function in C++ When you create a lambda function, you […]

Discover the power of ‘const’ in C++ through this comprehensive guide. This article will delve into various aspects of const usage in C++, so you can get excellent command over it. This C++ const article includes: Const Member Variable: A const member variable is a data member within a class that cannot be modified after […]

In C++, the memory layout of a class, both with and without virtual methods in the case of class hierarchy, is determined by how the compiler organizes the various components of the class. Let’s explore both scenarios: Memory layout of a C++ Class without Virtual Methods: Consider a simple class without any virtual methods: The […]
