What is called?

Called

In programming, particularly in the context of functions or methods, "called" refers to the action of invoking or executing a subroutine. When a function is "called," the program transfers control to the function, executing the code within the function's definition. After the function completes its task, it typically returns control to the point where it was called.

• Definition: The action of executing a function or method.

• Mechanism: Involves transferring program control to the subroutine's code block.

• Return: After execution, control is typically returned to the calling point.

• Importance: Fundamentally important to program modularity, reuse of code, and overall program structure. Understanding how a method%20is%20called is key to understanding program flow.

• Call Stack: Function calls create entries on the call%20stack. This data structure keeps track of active subroutines.

• Example: If functionA calls functionB, then functionB is said to be "called" by functionA.
