Invalid conversion

EagleSun (5)
Why is this giving me an error? it says invalid conversion from int to int*. not sure why... :S

I bolded where it says the error is, and where it is instantiated from.

What is item* supposed to do?
EagleSun (5)
I'm basically trying to insert item into the array of itemtypes. I typecasted it as a pointer because it gave me the same error regardless :(
Peter87 (11254)
Does this work? itArr[length] = item;
EagleSun (5)
negative. exact same error. honestly i can comment that entire line out and it still does it.
Peter87 (11254)
If I change to itArr[length] = item; the code compiles for me so I don't know what could be wrong.

The problem is on line 39 of 'Header'. You have to do the new in your constructor.

In your 'Specification' you can omit that try...catch block since that exception cannot happen there. While it can have an overflow

I think line 39 will work if he use C++11.
