i have kind of forgotten my basic turing knowledge i am required to create a program where you can enter an unlimited amount of numbers, and it will end once you enter -99 and it will find the sum of all the numbers that you entered i only know how to do this for a set number of entries, but how would I be able to keep entering an unlimited amount of numbers with no limit? |

You would have a loop, with an exit when num= -99, then get a number from the user and add it to a variable 'total'. |

you do the exit when at the top of the loop, the first thing |

no, no, no, put it at the VERY TOP of your loop. This is important as you get into larger programs. |

when i put it at the very top of the loop, the -99 gets added to my totalsum |

He's got it in the right place. There isn't a set place for an exit to go, it's just wherever it'll be most efficient. In this case, it's where he's moved it to. |
