Concurrency is the ability of different parts or units of a program, algorithm, or problem to be executed out-of-order or in partial order…
The builder design pattern allows for the creation of a complex object in a procedural manner. Imagine a scenario where you’re creating an application that allows the user to build their own house. Since you want your users to like your product, you provide them a tremendous amount of options. They can add pools, gardens, internet, walls, and even a roof (imagine that, a real roof!). There are several ways to approach this from a code perspective.
In software engineering, Creational Design Patterns deal with object creation mechanisms, i.e. try to create objects in a manner suitable to the situation. The basic or ordinary form of object creation could result in design problems or added complexity to the design. In this article of the Creational Design Patterns, we’re going to take a look at the much-hated & commonly asked design pattern in a programming interview. That is Singleton Design Pattern in Modern C++ which criticizes for its extensibility & testability. I will also cover the Multiton Design Pattern which quite contrary to Singleton.
