====== 2011.01.13 - most vexing parse ======

among many pitfalls in [[wp>C++]] there is so called "most vexing parse". as the name suggests, it is vexing. especially that it is a heritage from C.

consider given code:
<code c++>
#include <iostream>
struct S 
{
  S(){ std::cout<<"S()\n"; }
  S(const S&){ std::cout<<"S(cpctor)\n"; }
};

int main(void)
{
  S s( S() );
  return 0;
}

what will show on the screen? if your answer wasn't "nothing", that read on on explanation on [[http://arstechnica.com/civis/viewtopic.php?f=20&t=767929|the most vexing parse]]((many thanks to [[http://pl.linkedin.com/pub/marcin-skrobiranda/a/361/249|Strzygolak]] for sharing this link))...
