are pointers stored on the stack
Where is the stack pointer saved?
Regardless of the approach, the stack pointer is always located at the top of the stack, providing a reliable starting point for accessing stack memory.
As shown in the example, a smart pointer is a class template that you declare on the stack, and initialize by using a raw pointer that points to a heap-allocated object.
After the smart pointer is initialized, it owns the raw pointer.
What stores the stack pointer?
Simpler processors store the stack pointer in a regular hardware register and use the arithmetic logic unit (ALU) to manipulate its value.
Typically push and pop are translated into multiple micro-ops, to separately add/subtract the stack pointer, and perform the load/store in memory.
