Foo arr[2]={{0...

Basic C++: How do I initialize a struct member of a class?
Hi all. I've looked all over the place, but haven't found an answer to this. I have a C++ class with these protected members: struct tm _creationDate; struct tm _expirationDate; struct tm _lockDate; I want to initialize them at instantiation time.
