Answer 1

Probably because g starts at 1 instead of 0.

As for readability, I would put the closing bracket for the while loop on a new line. The rest looks fine to me.

Answer 2

the problem is (as @Dennis said) because the initial value of *g* is 1, so on the very first iteration of your loop

the statement

g += a

adds another one to the result leading to the undesired result.

the fix is to initialise *g* with 0 instead

here's the fix
