Hi

would you like to expand the nature of your problem further, we cant help if we do not know exactly what the problem is!!! Pointers is a rather large topic...

Somebody has actually helped me already. If I get confused later on, then I'll post a question. Thanks.

Actually, I was hoping you would explain your problem so I could learn one or two things.

what I was confused about was when I had cout << *p1, the variable would be outputted and not the memory address.
*p1 will display the variable because that is what it is pointing to.

Oh yeah.....correct me if I am wrong ... but a pointer can be stored only in a variable of type pointer?

e.g.

double *p, salary;
p = &salary

//therefore
salary = 90000;

//makes p equal to 9000

Right tracey?

Tracey - having the statement cout << &p should print out the address. * = pointer while & = address of
