You have an error in your print formats. You are printing four
variables: sbal, interest, deposit and ebal. These are declared as
int, double, int and double respectively. You are using the double
print format (%#.#f) for all four. You should either use the integer
print format (%#d) for the two integers or else make sure that the two
values in question are doubles by multiplying them by 1.0.
That is not your only problem, but it should get you some output to
look at. The other problems are more obvious once you can see the
output.

It isn't even printing anything anymore.
