Program isn't printing correctly

Question

I believe my program is still going through the if statements after it is declared invalid. It should print invalid filling status or invalid exemption status on the same line w

Answer 1

fillingStatus == 's' || 'S'

The above condition does not do what you appear to think it does. Try:

fillingStatus == 's' || fillingStatus == 'S'

The reason is that the == operator only compares one pair of values at a time. So your expression reads something like:

if (fillingStatus is 's') or ('S' is nonzero)

which is always true (since 'S' is always nonzero). The corrected expression reads like:

if (fillingStatus is 's') or (fillingStatus is 'S')

It might be worth noting that some other languages have less verbose ways of expressing this condition than the above C++ code. For example, in Python you can write:

if fillingStatus in ('s', 'S'):

which tests fillingStatus for either 's' or 'S'.
