No,We cannot change the address of memory of a variable
because the addresses to the variable are provided by the
OS. We can only assign this address to the pointer variable
like this:
int x,*p;
P=&x;
We can change variable value through pointer like this:
*p=4;
but we can't change the variable address through the pointer
and also we can't provide any address to the pointer
variable directly as an "numeric constant" so this statement
is incorrect:
&p=6;

what is associativity explain what is the precidence for * and & , * and ++ how the folloing declaration work 1) *&p; 2) *p++;
