Protocols and Declarations

Protocols and declarations are tools in programming to define and communicate expectations. A protocol specifies a set of methods or behaviors that a class or structure agrees to implement, ensuring consistency and interoperability. It's like a contract that guarantees certain functionalities will be available. Declarations, on the other hand, are statements that introduce and allocate space for variables, functions, or types in code, defining their names, types, and sometimes initial values. Together, they help organize code, enable different parts to work together smoothly, and clarify how various components should behave or interact within a program.
