Untyped template parameter

Template parameter classification type shape participates in non-type parameter.

Type template parameter: the parameter type name that appears in the template parameter list, followed by class or typename.

Non-type template parameter: use a constant as a parameter of the template, which must be a type parameter in the plastic family, otherwise it will not work. It can be used as a constant in the template.

Example:

/ / Type template parameter namespace wxj {/ / untype template parameter N is a constant parameter Can only be plastic family: int short char long custom types and other types cannot be used as cost type template parameters / / the result template class Array {public: Array (): _ size (N) {} must be confirmed at compile time. T & operator [] (size_t I) {return _ ARR [I] } const T & operator [] (size_t I) const {return _ ARR [I];} size_t size () {return _ size } bool empty () {return _ size = = 0;} private: t _ arr [N]; size_t _ size;}; void TestArray () {Array arr For (size_t I = 0; I < arr.size (); + + I) {arr [I] = I;} for (size_t I = 0; I < arr.size (); + + I) {cout
