6.6.2.Throwing an exception from a function outside the try block

#include <iostream>

using namespace std;



void f(int test)

{

  cout << "Inside f, test is: " << test << "\n";

  if(test) throw test;

}



int main()

{

  cout << "Start\n";



  try { // start a try block

    cout << "Inside try block\n";

    f(0);

    f(1);

    f(2);

  }

  catch (int i) { // catch an error

    cout << "Caught an exception -- value is: ";

    cout << i << "\n";

  }



  cout << "End";



  return 0;

}

Start
Inside try block
Inside f, test is: 0
Inside f, test is: 1
Caught an exception -- value is: 1
End"
