This chapter covers

• Understanding partial function application
• Fixing function arguments to specific values with std::bind
• Using lambdas for partial function application
• Are all functions in the world unary?

Most programming paradigms tend to provide a way to increase code reusability. In the object-oriented world, we create classes we can later use in various situations. We can use them directly or combine them to implement more-complex classes. The possibility of breaking complex systems into smaller components that can be used and tested separately is a powerful one.

In the same way that OOP gives you the tools to combine and modify types, ...
