C++ proggy ?

Pasted the whole thing below. Works great so far, what I now need to do is instead of having the user type 1,2,3 or 4 for the car type, is type t,f,c, or d. Every time I try to assign letters to the constants, the program hangs. Do I need a different swtich statement. Do switches only work with #'s? Thanks....

Code:

#include <iostream>
#include <iomanip>

a switch statement can use chars, just change the choice variable to a char and use...

case 't':
break;
case 's':
break;
....

Nevermind...I'm such a noob. Forgot the quotes.....need em for chars and not #'s...grrr. Thanks again!

thanks....

but when i do that...i get errors.....

error C2065: 'E' : undeclared identifier
error C2051: case expression not constant

???

better post the new code...

Did you change the variable "choice" type from int to char? It should work with that (it works for me).

yea i got it. It was the <lack of> quotes. I edited my message instead of posting new. Thanks for all the help everybody....
