What is the main advantage of using a stack for function calls?
Step 1: Understand what a stack is. A stack is a data structure that works like a stack of plates, where you can only add or remove the top plate.
Step 2: Know that in programming, when a function is called, the program needs to remember where to go back after the function finishes. This is called the return address.
Step 3: Realize that when a function is called, it may have its own local variables (like temporary storage for that function).
Step 4: Learn that a stack keeps track of all the function calls, including their return addresses and local variables, in a last-in, first-out (LIFO) order.
Step 5: Understand that this organization allows functions to call themselves (recursion) because the stack can handle multiple function calls at once, remembering where to return to each time.
