Exceptions in destructors

In C++11 destructors default to noexcept so you have to go out of your way to make them throw. See throwing a vector in a destructor.

#include <exception>
#include <iostream>
#include <vector>

// Note the braces
void exception1() try { throw 1; } catch (int e) {
  std::cout << "Caught " << e << std::endl;
} catch (const std::out_of_range &oor) {
  std::cout << "Caught OOR\n" << oor.what() << std::endl;
} catch (const std::exception &e) {
  std::cout << "Caught " << e.what() << std::endl;
} catch (...) {
  std::cout << "Caught ellipsis" << std::endl;
}

void exception2() {

  using namespace std;

  // Simple
  try {
    throw 2;
  } catch (int e) {
    cout << "Caught exception " << e << endl;
  }

  try {
    vector<int> vec(5);
    vec.at(6);
  } catch (exception &e) {
    cout << "Caught exception " << e.what() << endl;
  }
}

int main() {

  exception1();
  exception2();
}
