Question

The Question

1.)Is it possible to declare a pointer variable to reference to the memory address of a constant??I’ve tried this before pt = &20;(**pt is a pointer variable) but it’s not working , so does it mean we can’t do it??By the way if it’s possible how am i going to work it out??

Answer 1

No. You must do this:

const int x = 20;
const int* p = &x;
