Question

Suppose we have following two classes:

class Temp{
 public:
  char a;
  char b;
};
class Final{
 private:
  int a;
  char b;
  char c;
 public:
  Final(Temp in):b(in.a),c(in.b){}
  //rest of implementation
};

suppose the only use of objects of Temp class is to construct objects of Final class, so I wonder if in current standard of c++ , we can using a macro or somehow tell the compiler, since this object of Temp class which I’m defining is only used in one line of code and that is as argument of constructor of Final class; take a name for it yourself so I don’t bother myself taking one name for each object Of Temp class?

Answer 1

there’s no such thing as I want in current c++ standard, but in upcoming c++0x standard, to initialize an object of the Final class, we can write:

Final obj({'a','b'}); 

So no naming for initializer object of the Temp class !!!
