Question

When a value is pushed onto the stack, what happens to the address stored in the stack pointer?

Answer 1

Pushing a value onto the stack decreases the stack pointer to point to the new top element, as stacks typically grow downwards in memory.

Step-by-step explanation:

When a value is pushed onto the stack, the address stored in the stack pointer typically decreases to point to the new top element on the stack. This happens because stacks usually grow downwards in memory space in most computer architectures. For example, if the current stack pointer address is 0x0032, and a new value is pushed onto the stack, the stack pointer might decrease to 0x002E if the pushed value occupies 4 bytes (assuming a 32-bit system architecture).
