compling issues - const issue

Code:

---

#include <iostream>

class TestPrint
{
public:

  void Print()
  {
    std::cout << "TestPrint" << std::endl;
  }

  void Print() const
  {
    std::cout << "const TestPrint" << std::endl;
  }

  void Print() volatile
  {
    std::cout << "volatile TestPrint" << std::endl;
  }

  void Print() const volatile
  {
    std::cout << "const volatile TestPrint" << std::endl;
  }
};


int main(int argc, char* argv[])
{
  TestPrint normal_test;
  normal_test.Print();

  const TestPrint const_test;
  const_test.Print();

  volatile TestPrint volatile_test;
  volatile_test.Print();

  const volatile TestPrint const_volatile_test;
  const_volatile_test.Print();
}

coletek@spamisgood:~/sandbox/cc> g++ eg.cc
eg.cc: In function ‘int main(int, char**)’:
eg.cc:34: error: uninitialized const ‘const_test’
eg.cc:40: error: uninitialized const ‘const_volatile_test’

What do I initialize them to tho??

Fixed, just add a default empty constructor.

Which compiler are you using? That shouldn't make any difference because your class will have a default ctor provided for it by the compiler.

Your posted code compiles with no errors when using Visual Studio 2008.

It's the version number I was after (I somehow managed to completely omit the word "version" from the question).

Are you sure that what you posted is the entire code that generated the error?

Interesting - Comeau fails it with the same errors. Presumably implicit default ctors are not considered wrt const objects. I'll see if I can find the relevant section of the standard.
