Why won't this work?

class Base
{
public:
   Base()
   {
   }

   Base(const char* msg)
   {
   }
} ;

class Sub : pulic Base
{
   Sub()
   {
   }

   Sub(const char* msg)
   {
      Base::Base(msg) ;
   }
} ;

Why isn't the above code the same as this one (that works):

class Base
{
public:
   Base()
   {
   }

   Base(const char* msg)
   {
   }
} ;

class Sub : pulic Base
{
   Sub()
   {
   }

   Sub(const char* msg) : Base(msg)
   {
   }
} ;

Rome did not create a great empire by having meetings, they did it by
killing all those who opposed them.

Constructor is not an ordinal function. You can't invoke ctor as other functions: it's C++ syntax rule. See Stroustrup's book about C++ design history...
