6.1.2.Throwing an exception from a function called from within a 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
