Programming Help

I have a programming assignment to do. It computes a persons bowling score. I have to use a function to do this and I can't figure out how. Any help would be appreciated

Well, let me paraphrase: you want us to do your homework for you, providing us none of your effort and expecting to get a positive response? Shockingly, your wrong.
