Does C++ allow default return types for functions?

In C the following horror is valid:

  return 42;  // return type defaults to int.

But, what about in C++? I can't find a reference to it either way...

My compiler (Codegear C++Builder 2007) currently accepts it without warning, but I've had comments that this is an error in C++.


It's ill-formed in C++. Meaning that it doesn't compile with a standard conforming compiler. Paragraph 7.1.5/4 in Annex C of the Standard explains the change "Banning implicit int".
