[comp.lang.c++] Help needed with constructor syntax error

sml@beach.cis.ufl.edu (Shein-Fong Law) (09/10/90)

   I have compiler error when I compiled the following constructor :

A::A(char* name,B* pointer):(name) // I want to pass 'name' to Base class
construtor.


   where class A , B and Base are as follows:

class B : public Base
 {
   public:
    B(char*);  // This constructor requires char* (No default)
  };
class Base
 {
   public:
    Base(char* name=0);  // if name is not supplied, default = NULL
 };
class A: public Base
 {
   private:
     char* priv_name;
     B* to_B;
   public:
    A(char*,B*);
 };

 Why did my compiler (glokenspiel C++ 1.2 )give error ("syntax error") to
the above constructor for A ?

 How can I correct the error ?


 Thanks in advance. Please email to me.

Wrong declaration order. A base class must be defined before it can be used as a 
base class. A class can be used in a pointer or reference declararation before 
it's definition, but not as variable, class member or base class.

                Gruss, Andreas
