This program is supposed to print a letter grade and a pass/fail line for a numeric score – and both
letter_grade and passed are already correctly implemented. It just doesn’t compile, for two independent
reasons, one from each of this module’s first two lessons.
Fix it one error at a time: submit, read whatever error comes back first, fix only that specific problem, then submit again. You should recognize both errors from the last two exercises – neither one requires writing new logic, only fixing how a function is declared.
