When you use a while loop to compute the product of several values, you should initialize the variables holding the product to .
a. 0
b. 1
c. null
d. there is no need to initalize it

b.1

Explanation:

When we are using while loop to compute the product of several values we need to initialize the value holding the product to 1 because when we multiply something with 1 it will give the same number.

If we initialize it with 0 the product will come out to be 0 because  anything multiplied by 0 is 0.

we cannot initialize it with NULL because it is not a pointer.

We need to initialize the number since it contains garbage values so it will give product with that value.
