类模板的派生四种情况类模板派生出新的类模板模板类派生出类模板普通类派生出类模板模板类派生出普通类

类模板派生出新的类模板template<typenameT1,typenameT2>classbase{……};template<typenameT1,typenameT2>classderived:publicbase<T2,T1>{……};intmain(){derived<int,double>d;return0;}classbase<double,int>{……};classderived<int,double>:publicbase<double,int>{……};

模板类派生出类模板template<typenameT1,typenameT2>classbase{……};template<typenameT1,typenameT2>classderived:publicbase<double，int>{……};intmain(){derived<int,double>d;return0;}classbase<double,int>{……};classderived<int,double>:publicbase<double,int>{……};

普通类派生出类模板classbase{……};template<typenameT1,typenameT2>classderived:publicbase{……};intmain(){derived<int,double>d1;derived<int,float>d2;return0;}classderived<int,double>:publicbase{……};

模板类派生出普通类template<typenameT1,typenameT2>classbase{……};classderived:publicbase<double,int>{……};intmain(){derivedd;return0;}classbase<double,int>{……};
