Answer 2

There is none. In the example case I prefer typename since typename actually denominates what U and T are intended to be: any type you want (and in the example case it's int and char). If I would only pass classes, I would use the class keyword.

Answer 3

Btw, to name stuff clearly: U and T are template parameters and the template is the class A.

Answer 4

You mean partial specialization?

Answer 5

I mean, if I need to specialize a class which uses 2 different templates, let's say T and U, if I need to make a special behaviour for when U is a char, what'll be the syntaxe?

Answer 6

Btw, some older compilers have problems with the partial template specialization. In other words: it doesn't work, even though it's in the standard they try to implement.

Answer 7

Thanks! And BTW, what is the difference between naming templates class or typename?

Answer 8

Thx for the precision :)
