Key Concepts

Function Prototype

A function prototype is a declaration that specifies a function's name, return type, and parameters without providing the complete definition. It allows the compiler to perform type checking on function calls even when the full function definition appears later in the code, thereby offering more flexibility in the order of code segments and improving code maintainability.

Forward Declaration

Forward declaration refers to the practice of declaring the existence of an entity, such as a function, before its actual definition. In programming, particularly in languages like C and C++, forward declarations serve to inform the compiler about a function's signature, eliminating the need for the function's full definition to appear prior to any calls to it.
