Does the ring of continuous functions over the real numbers have no zero divisors? If no 0 divisor, how can I prove it? Else, what is a counter example?

you should be able to define two nonzero continuous functions whose product is zero function...
 
Wow, yea probably. I want to find easy ones. Give me until tomorrow. I'm dead tired. Thanks
 
Keep in mind if a function is defined piecewise such that each piece is continuous, and all the endpoints match up, you've defined a new continuous function
