Need to know what's the difference when using Templates between:
template<class T> and
The first is legal, the second is not. But if you meant typename rather than typedef, the two are functionally identical.
My bad i meant.
template<typename T> You said they are functionally identical. Is one of them from C and the other from C++, is one of them or both of them Standard?
C doesn't have templates at all, so both class and typename are unique to C++. They're also both standard, but class is an older form, so you're likely to see it more often. There are various personal preferences for how to use it; my preference is to use typename pretty much exclusively.
 class was used originally because the designers didn't want to add a new keyword to the language. But when a new keyword was needed for other things (typename), it was basically overloaded to handle this job as well.
Ok. Thanks that's exactly what i needed to know. You are simply da best Narue !
