Dynamic Arrays inside Classes
Hello,
I'm trying to write a class that contains data and a dynamic array of the same class type.
Is that possible?And how can I write that?

That's basically the same, KurtVon. As long as you don't include an instance of the class in the class itself, it's fine. So, this will NOT work :
class Test {
Test dyn_arr;
};
for obvious reasons (you'd have an infinite inclusion, and an infinite size of the Test class).
The example KurtVon gave also works, because the elements of the vector are not stored in the class body, but rather a "reference" to the elements.
class Test {
Test dyn_arr;
};

May I ask why you gave a B grade ? Is something still unclear ? If so, you can always ask for clarification ... You don't need to accept a reply that doesn't fully answer your question !

I thought I gave it an A?! Must have pressed enter when I selected A?
How can I correct this? *Sorry!*

There's no problem. I just wanted to make sure that you didn't select the reply without understanding it.

#include <vector>
class DynArrayTest{
public:
DynArrayTest();
~DynArrayTest();
std::vector<DynArrayTest> testArray;
};
