RE: Calling a parameterless constructor from a parametered one

["Lev Assinovsky" <LAssinovsky@xxxxxxxxxxxxxxxxxxxx>]

The statement
//    baseClass(T val)
//       : baseClass()
//{
is wrong I think and isn't needed since you have
   baseClass(T val)
      : theVal(val)
   {
   }
========================================
#include <iostream>

template <class T, T defaultVal>
class baseClass
{
public:
   baseClass()
      : theVal(defaultVal)
   {
   }

   baseClass(T val)
      : theVal(val)
   {
   }
//    baseClass(T val)
//       : baseClass()
//    {
//       theVal = val;
//    }

   void printVal()
   {
      std::cout << theVal << std::endl;
   }

private:
   T theVal;
};

class intClass : public baseClass<int, 5>
{
public:
   intClass()
      : baseClass<int, 5>()
   {
   }

   intClass(int val)
      : baseClass<int, 5>(val)
   {
   }
};

main()
{
   intClass a(10);
   a.printVal();

   baseClass<int,1>b;
   b.printVal();
}

All,

Could somebody tell me why the commented out constructor in the attached code 
doesn't compile (it doesn't make sense to do that in this example, but it 
would do in some code I'm currently writing ;-).

TIA,

Fred
