Can I assign a value to a pointer?

Answer 1

When you initialize the value, you store a value in that pointer itself (like if the star wasn't there, yeah, that's a bit confusing).

So what you store in there, has to be an address.

int n;
int *p = &n;

Answer 2

The type of value you assign to a pointer is a memory address.

And by using *, you can assign a value to the place the pointer is pointing to, but the value of the pointer itself stays the address of that place.

Answer 3

I can't do this : int *p = 45 ; ?? Because when I want to print the value it is pointing to I use *p
