this is not home work directly i am trying to add a loop to the already existing HW which is math function aspect. i cant seem to figure out how to just make a simple Yes or No loop. i have no problem making the loop if it needs to count... any way any one have any suggestions on how to help a newbie?

thanks in advance!

Re: trying to make a "Do While" loop; loop

put the do in before this line:

cout << " Please enter two numbers: ";

and the while after the closing brace of the switch statement.

C++ Syntax (Toggle Plain Text)
   } //end of switch statement
cout << "\n Would you like to perform another calculation? " << endl;
cin >> option;
}while ( option == 'y' );
   } //end of switch statement
cout << "\n Would you like to perform another calculation? " << endl;
cin >> option;
}while ( option == 'y' );
