what would be the difference using *pointer and &

Question

if they both gonna point out to the adress in ram??

Answer 1

* is the 'point to' operator. It tells the program you want to point to something (most of the times, an address).

& is the 'address-of' operator. It tells the program to return the address of anything which comes after it.

E.g.

int *p;
int q = 39;
p = &q;

// now, p stores the address of q.

cout << *p;

// this tells the program to print which is pointed by p.
// outputs 39.

Answer 2

There is NO DIFFERENCE b/w pointers and references

Answer 3

'&' gets a pointer 'p' address memory cells where it is stored variable 'x'.
'*' gets a pointer 'p' the contents of memory from the address which is stored in the variable 'x'.
Hatsy Rei is right :)
