2. What is true about a class template?

In C++11, the declaration of the class template can be placed in a header file (.h), and the definitions placed in the implementation file (.cpp) without the keyword 'extern'.

A template class is not actually created by the compiler until it parses a line of code creating a new instance of that class.

Only the class declaration need be prefaced with 'template , the class definitions, if defined outside the class specification, need not be prefaced with 'template .

'template ' is not the same as 'template ' for all types datatype.
