What is ( called?

Called, in the context of computer programming and more generally, computing, refers to the invocation of a subroutine, function, or method. When a piece of code "calls" another piece of code, it means it's executing that other piece of code. This is a fundamental concept in structured and object-oriented programming, enabling modularity and code reuse.

Here are some key aspects related to the concept of "called":

• Function Calls: In procedural programming, called often refers to a function%20call. A function is a self-contained block of code that performs a specific task. Calling a function involves providing the necessary arguments (if any) and then executing the code within the function.

• Method Calls: In object-oriented programming (OOP), called is frequently used in the context of a method%20call. A method is a function that is associated with a particular object. Calling a method on an object means executing the function associated with that object.

• Call Stack: When a function or method is called, information about the calling context (e.g., return address, local variables) is typically stored on a call%20stack. This allows the program to return to the correct location after the called function or method has finished executing.

• Call by Value vs. Call by Reference: These are different mechanisms for passing arguments to functions or methods. Call%20by%20value creates a copy of the argument, while call%20by%20reference passes a pointer or reference to the original argument.

• Callbacks: A callback is a function that is passed as an argument to another function, with the expectation that the callback function will be executed at some later point. This is often used in asynchronous programming or event handling.

• Recursive Calls: A recursive%20call occurs when a function calls itself. This is a powerful technique for solving problems that can be broken down into smaller, self-similar subproblems.

• API Calls: When interacting with external libraries, services or operating systems, programmers frequently make API%20calls. An API call is a request to a service to perform an action or retrieve data.
