In programming, calling a predefined block of code by its name is known as what?

Invoking a predefined block of code by its name is a function call. A function groups together instructions to perform a specific task and is designed to be reused from different parts of a program. You trigger that block by referencing its name, and you can pass inputs and receive an output. This makes code more modular and readable, since you can build complex behavior by composing calls to well-defined functions. This is different from a variable, which simply holds data; a class, which serves as a blueprint for creating objects; and a loop, which repeats a set of instructions driven by a condition. For example, defining a function like greet() and then calling greet() runs that block of code whenever you need it.
