Because I had no time to do a puzzle today myself and there was still one from my former colleague Thomas in the queue I will present this puzzle today.
The question is what the following application does produce when built with a standard compliant compiler.
#include <iostream> struct A {}; void foo(bool t) { if (t) throw A(); } void bar(bool t) { try { try { foo(t); throw; } catch (const A&) { std::cout << "catched const A&" << std::endl; throw; } } catch (...) { std::cout << "catched ..." << std::endl; } } int main() { bar(true); bar(false); std::cout << "done." << std::endl; }
