Q$4.$ Call stack and stack frame

$1)$ What is the call stack? What is a stack frame? Explain both and their relationship.

$$

When a function is called, its stack frame is pushed onto the stack, storing information such as the return address, local variables, and function parameters. As functions finish executing, their stack frames are popped from the stack, discarding the stored information. The function call stack ensures the proper sequencing of function calls and allows for the efficient allocation and deallocation of resources. Understanding how the function call stack and stack frames work is crucial for designing and implementing structured and organized programs.
