Constant

Question

how we can change the value of constant.?
const int x=10;
x++;
cout<<x;

Answer 1

you can't change the value of const variables.
but you can change memory address like...

const int a = 1;
const int *p = &a;
cout << ++p;

Answer 2

You can't, that's the whole idea of constant.

Answer 3

You can't change the value of a constant. The point of a constant is that it cannot be changed. You can change the value of a variable, though.
