Cash Register

[Larry Bates]

Let's see:

1) If user inputs text, program crashes (not good)
Probably should use raw_input and put float() inside
a try block.

2) I can't figure out how program ever stops (e.g. b
is set to 1 and never reset to exit the while b!=0
loop).

3) Sales is mispelled in the last print statement

4) Use inplace incrementing (e.g. v+=s, s+=a)
instead of s=s+a, v=v+s

5) What is t variable used for?

Good Luck.
