List or IList [closed]
...int>, but is of fixed size. The contract for ICollection<T> (the base of IList<T>) requires the code that uses it to check the IsReadOnly flag before attempting to add or remove items from the collection. The contract for List<T> does not.

Why does C++ need a separate header file?
...to do with this, it's the fact that the compilation environment for C++ is based so closely on that of C.
Converting my comments to answer your follow-up question:
How does the compiler find the .cpp file with the code in it

What is the difference between mocking and spying when using Mockito?
...ult value - 0 and null
Spy is a cloned double object. New object is cloned based on a real object but you have a possibility to mock it

MyISAM versus InnoDB [closed]
I'm working on a projects which involves a lot of database writes, I'd say ( 70% inserts and 30% reads ). This ratio would also include updates which I consider to be one read and one write. The reads can be dirty (e.g. I don't need 100% accurate information at the time of read).
