What does the term 'call' relate to in programming?

The term 'call' in programming specifically relates to the act of executing a function. When you "call" a function, you are instructing the program to execute the block of code defined within that function. This is a fundamental concept in programming as functions are reusable pieces of code that can take input (arguments), perform actions, and often return output. The process of calling a function allows developers to organize code better, create modular programs, and enhance code reusability.

In contrast, starting a variable pertains to variable initialization before use, declaring an argument involves defining parameters for a function, and ending a process does not relate directly to the action of invoking a function within programming. Each of these tasks serves different purposes in the coding landscape, but the essence of a 'call' is inherently tied to function execution.
