In what situations does the stack grow during program execution?

The stack growth occurs when a program calls new methods or functions, and for each call, a new stack frame with local variables and parameters is allocated. The main situations that cause stack growth are:

• Method or function call: each call adds a new frame to the stack.
• Recursion: with deep recursion, the stack grows with each nested call.
• Creation of local variables: when a method is called, memory is allocated on the stack to store local variables.

For example, in recursive calculation of factorial, the stack will grow with each call until it reaches the base case.
