Question
What is a stack pointer register, describe briefly.?
Answers
The Stack pointer is a sixteen bit register used to point at the stack.
In read write memory the locations at which temporary data and return addresses are stored is known as the stack.
In simple words stack acts like an auto decrement facility in the system.
The initialization of the stack top is done with the help of an instruction LXI SP.
In order to avoid program crashes a program should always be written at one end and initialized at the other.   Your Comment
