A stack pointer is a pointer that points to the top element of a stack. The stack is a data structure that allows elements to be added and removed in a last-in-first-out (LIFO) order. When an element is added to a stack, it is placed on top of the stack, and when an element is removed from a stack, it is removed from the top of the stack.
The stack pointer always points to the most recently added element on the stack. When an element is removed from the stack, the stack pointer is decremented to point to the next most recently added element. Is stack pointer in RAM? No, the stack pointer is not in RAM. The stack pointer is a register that points to the top of the stack. Why stack pointer is 16-bit? The stack pointer is 16-bit because that is the native size of the processor. The processor can access data on the stack more efficiently if the stack pointer is the same size as the processor. What is stack pointer and program counter? The stack pointer (SP) is a register that holds the address of the top of the stack. The program counter (PC) is a register that holds the address of the next instruction to be executed. Why stack pointer is used? The stack pointer is used to keep track of the current position in the stack. It is used to store data and to keep track of the current position in the stack. What is main stack pointer? The main stack pointer is a pointer that points to the top of the main stack. The main stack is where the program's data is stored. The main stack pointer is used to access the data in the stack.
