Congratulations, you've received the ultimate programmer dad gift - a mug that basically declares your father superior to all other fathers using C syntax. The code iterates through all dads in existence, marks yours as kBestDad , and relegates everyone else's to kRegularDad status. It's basically a Father's Day card written by someone who thinks semicolons are punctuation marks for real life conversations. The only thing missing is a function that prints "Hi Hungry, I'm Dad" whenever you mention food.
