The previous section introduced the simplest atomic type in C++11, std::atomic_flag, but it's too limited with only test_and_set and clear APIs. It doesn't meet other requirements like store, load, exchange, and compare_exchange. This article will explore the more comprehensive std::atomic class. Basic std::atomic Types Explained Introduction t ...

Lambda Expressions A lambda expression in C++11 follows the syntax: [capture-list] (parameters) mutable -> return-type { statement }. Capture List ([capture-list]): Defines variables accessible within the lambda. It must be present and is used by the compiler to identify a lambda. Variables can be captured by value or by reference. [v]: C ...

Maximum Profit Scheduling Problem This problem addresses the optimization of sales revenue for a set of products, where each item possesses a specific profit margin and a hard expiration deadline. You possess a capacity to sell exactly one product per day. Once a product's deadline has passed, it cannot be sold. The objective is to determine th ...

The auto keyword, introduced in the C++11 standard, is a powerful feature for type inference. It allows the compiler to deduce the type of a variable from its initializer, leading to more concise and flexible code. This article explores the principles behind auto and demonstrates its practical applications in various programming scenarios. At i ...

The producer-consumer problem is a classic synchronization challenge in concurrent programimng. This article demonstrates various implementations using C++11 threading and synchronization primitives. Shared Code #include <cstdlib> #include <condition_variable> #include <iostream> #include <mutex> #include <thread> ...

Understanding atomic_flag The atomic_flag is the simplest atomic boolean type in C++11's <atomic> header, supporting only two operations: test_and_set and clear. Constructor and Initialization atomic_flag() noexcept = default; atomic_flag(const atomic_flag&) = delete; atomic_flag has only a default constructor. Copy construction is d ...

Smart pointers are a powerful feature introduced in C++11 that automate memory management, significantly reducing the complexity of manual resource handling. The C++ standard library provides three main types of smart pointers: std::unique_ptr, std::shared_ptr, and std::weak_ptr. std::unique_ptr implements exclusive ownership, ensuring only one ...

Lambda expressions were introduced in C++11 to simplify the use of function objects, especially when passing custom logic to standard algorithms like std::sort. Motivation for Lambda Expressions In C++98, defining custom comparison logic required creating a separate functor class: struct Product { std::string name; double price; int ...

Smart pointers, introduced in C++11, provide automatic memory management by controlling the lifecycle of dynamically allocated objects. They help developers avoid common pitfalls like memory leaks and dangling pointers. The standard library offers three main types: std::unique_ptr, std::shared_ptr, and std::weak_ptr. This guide covers they func ...

Introduction to Aspect-Oriented Programming Aspect-Oriented Programming (AOP) serves as a valuable supplement to Object-Oriented Programming (OOP) by addressing cross-cutting concerns. While OOP effectively models vertical, hierarchical relationships through inheritance, it struggles to encapsulate horizontal, shared behaviors that span across ...
