    Angry Undefined Prefrence 'printf' Help???

    In C, the case of a letter matters. 'A' isn't the same as 'a'. Likewise, printf isn't the same as Printf.

    Also, you're putting your if statements inside quotes, can't you see by the coloring that something is wrong?

    It's okay if you fail the exam, maybe next time you'll be more prepared for it.

    I guess process of elimination is not taught in programing class in college where people pay a large amount of money to have someone show them a few things on programming then they toss them out to the wolves to try and figure out the rest.
