What did I point at?

Can someone explain what I pointed at? I was playing with pointers to better understand how they work. Now I'm confused.

Answer 1

I knew I was pointing to something other than the variable a, the point of writing the code was to see what would happen if i send it to something other than a variable. I'm aware of the difference between *wut and wut. What I wanted to know is what the info the pointer returned was. Shouda worded my question better. Thanks for the help tho!

Answer 2

OK..
There is a big problem:
You don't know the difference between 'wur' and '*wur'.
int a=4; // classic variable
int *ptr ; // pointer on an int
Now how can 'ptr' point on 'a' ?
ONE way :
ptr=&a;
a pointer store an adress.
a's adress is &a (&a==0x45cg4i or something like that)
Now that 'ptr' point on 'a', you have :
ptr==&a==0x45cg4i; // true
*ptr==*&a==a==4; // true
BUT ptr!=a and *ptr!=&a.

Answer 3

A pointer can only have an adress as value. Just like a char can only have a char.
int *ptr;
int u=2;
ptr=56; // error
ptr=u; // error
