Problems with Destructors

Question

I cannot figure out why this keeps crashing on me. The code makes it almost to the end. Specifically it makes it to the print(copyArray); line. I have no idea where I went wrong, but it keeps popping up the same error.

I have tried calling the destructors, but apparently I am not doing it right.

elementArray.~ManagedArray();

EDIT:

I read that entire thread you posted and still cannot find the answer. I did however figure out if I comment out the print functions it does not occur. But once I print it crashes at the end of the function.

Error I am receiving

#include <iostream>
using namespace std;

    private:
        int numberOfElements;

    public:

        float get(int index);

        ManagedArray(ManagedArray & ma);
        ~ManagedArray() {delete [] elements;}
