switch statement that uses loop

Hi
I am trying to use a loop in this switch statement so i can have the user select another choice.
here is my code. choice is an interger variable and the cases are funtion calls. they all work except i cant figure out the loop and where to put it. I thought it would go in the default section of the switch. hope you can help


switch(choice)
{
case 1: smallest(first,second,third,fourth,fifth);
break;
case 2: largest(first,second,third,fourth,fifth);
break;
case 3: sum(first,second,third,fourth,fifth);
break;
case 4: average(first,second,third,fourth,fifth);
break;
case 5: printDisplay(first,second,third,fourth,fifth);
break;
default: cout<<"\aError! choice is (1) or (2) or (3) or (4) or (5) please try again\n";
break;

}

Put the switch stament in the loop like so

choice == TRUE;
while(choiche)
{
switch(choice)
{
case 1: smallest(first,second,third,fourth,fifth);
break;
case 2: largest(first,second,third,fourth,fifth);
break;
case 3: sum(first,second,third,fourth,fifth);
break;
case 4: average(first,second,third,fourth,fifth);
break;
case 5: printDisplay(first,second,third,fourth,fifth);
break;
default: cout<<"\aError! choice is (1) or (2) or (3) or (4) or (5) please try again\n";


""Ask the user if they want to continue"" and set choice to FALSE if they don't""
}
}

That will work but you used the same var twice when you should use 2 different variables for the loop and the switch where the one in the loop is set to true originally. Also, a do...while loop will work in this situation too.
