Learn how to implement the Strategy pattern in C++, a design pattern that allows you to define and use different algorithms dynamically. See examples and code snippets.

The strategy pattern has several benefits for your code. First, it helps you follow the open-closed principle, which states that your classes should be open for extension, but closed for modification.

Numerous design patterns let you extend functionality; for example, in Java Design Patterns you’ve seen how to extend functionality with the Proxy, Decorator, and Strategy patterns.

Typically, the strategy pattern stores a reference to some code in a data structure and retrieves it. This can be achieved by mechanisms such as the native function pointer, the first-class function, ...

Strategy Pattern in modern C++ This approach comes in handy when we build a structure, and we could have several options for implementing a specific procedure. The example is a fictional customer ...

So what is the Strategy Pattern, you may ask? Essentially it is a way to evaluate an input at runtime and execute predefined code based off of that input. This is JavaScript, a dynamic language so we ...
