Use std::vector instead of an array.

To be more clear, there is no function to find the size of an array, since an array is just a glorified pointer. You have to manually keep track of the size of the array yourself.

Oh - use a vector Wink

Dude, you want to tell me why in all your C++ posts you use std:: ? Just put

code:
using namespace std;

because its more standard.. if we simply told them to use vector, then they'll come back saying it doesnt work and blah blah.. but if u use std::vector, then it'll work no matter what, plus it keeps the file size down

Lots of stuff lives in the std namespace. I don't want all of it my namespace.

i need to use pointers tho.... and i need to se how many values are passed through the parameters. Is there any way of doing this with pointers or arrays?

How about showing us what you do have, or even describing what you're actually trying to accomplish.
