c++ - Try block behavior with cout statements when an exception is thrown -

if try block contains cout statements before exception thrown in same block, statements printed console, or behave if try block never executed? example:

void foo() {   try   {     cout << "1" << endl;     cout << "2" << endl;     bar();               //exception thrown in function, caught below   }    catch (exception e)   {     cout << e.what();    //assume message "error"   } } 

would output of function be

1 2 error 

or

error 

the output

1 2 error 

the exception not "undo" effects of

cout << "1" << endl; cout << "2" << endl;
