Funktionsaufrufstapel

Funktionsaufrufstapel is a German term used in computer science to refer to a call stack. In programming, a call stack is a region of memory where a program stores information about the active subroutines or functions that are currently being executed.

The call stack is used to keep track of the sequence of functions that are being called from within other functions. It stores information about the parameters passed to each function, as well as the local variables and function return addresses. When a new function is called, its information is added to the top of the call stack. When the function returns, its information is removed from the top of the call stack.

The call stack is a crucial data structure in programming, as it allows programs to manage the flow of control between different functions and subroutines. It is used in many programming paradigms, including structured programming, object-oriented programming, and functional programming.

In computer science, the call stack is often used as a metaphor for the human process of stacking and unstacking objects. Just as a stack allows objects to be easily added and removed from the top, a call stack allows functions to be easily added and removed from the call stack.

A key characteristic of a call stack is its Last-In-First-Out (LIFO) behavior, meaning that the most recent function added to the stack is the first one to be removed. This property makes the call stack a useful tool for managing the execution of programs with recursive function calls.

Overall, the funkionsaufrustapel, or call stack, is a fundamental concept in computer science that plays a crucial role in the management of program execution and function calls.
