hi all,


Nontype template parameters are declared much like variables, but they
cannot have nontype specifiers like static, mutable, and so forth. They
can have const and volatile qualifiers, but if such a qualifier appears
at the outermost level of the parameter type, it is simply ignored:

template<int const length> class Buffer; // const is useless here
template<int length> class Buffer; // same as previous
declaration



can anyone give an exmaple of how to write a const/volatile useful
templates to illustrate the case contrasted to the "
but if such a qualifier appears at the outermost level of the
parameter type, it is simply ignored:"
