variable nr of objects

[v.niekerk]

Hi,

I would like to be able to create a variable number of objects. So, when
there's a class Thing, instead of

Thing thing1, thing2, thing3

do like

cin >> nr;
for (x = 0; x < nr; x--)
{
Thing thing[x];
}

I searched the net for info but found no answer and tried but get errors.
Is this possible anyway?

Thanks.

Perhaps something like:

std::cin >> nr;
std::vector<Thing> items(nr);
// do stuff with items

Thank you for answering, but I don't fully understand.

Do you mean items(nr) as an array ?

You seem a bit lost: buy a couple of C++ books such as "The C++
Programming Language" by Stroustrup.

I have that book and searched it for this subject. Will search again...
