Can you explain what is meant by 'stack' in the context of programming?

In programming, a stack is a data structure that operates on the Last In, First Out (LIFO) principle, meaning the last added element is retrieved first.

In the context of programming, a stack is often used to store information about function calls: when a function is called, the return address and local variables are placed on the stack, and when the function finishes, this information is retrieved.

Example:

• Function A calls function B — the context of A is placed on the stack.
• Function B executes and then finishes — its context is removed from the stack.

The stack is also used for memory management during program execution, especially for local variables and function parameters.
