    1st, use code tags and indent. makes code easier to read.

    2nd, use endl at the end of your cout statements, it flushes the buffer and causes a "\n" internally.

    3rd, your ifs on 2 and 3 should be "else if"

    4th, don't you want to loop and do the menu again if you aren't choosing 3?

    You will also need to add cin.ignore() after cin>>choice. It will get rid of the return at the end of the string, so your first getline in the IF (whichever is executed) won't be empty.
