c++模板元编程2 - c++编程基础

h "; ret += get_description (); ret += " and it pointer to function returning "; ret += get_description (); return ret.c_str(); } }; template struct get_description { operator const char* () { std::cout << typeid(T).name() << "\n"; static std::string ret = "pointer to function with "; ret += get_description (); ret += " returning "; ret += get_description (); std::cout << typeid(T).name() << "\n"; return ret.c_str(); } }; template struct get_description { operator const char* () { std::cout << typeid(T).name() << "\n"; static std::string ret = "this is a pointer function with "; ret += get_description (); ret += " and it pointer to function with "; ret += get_description (); ret += " returning "; ret += get_description (); std::cout << typeid(T).name() << "\n"; return ret.c_str(); } };
测试代码：

void fun_text_descriptor()
{
	//std::cout << get_description
        
         () << std::endl;
	typedef int (*FunPoint[10])(char*);
	std::cout << get_description
         
          ()<< std::endl; std::cout << get_description
          
           () << std::endl; }

好了就做了这几个题！！！！
