You need to initialize "totslices"
And just curious, why is the number of guests variable "x" ? The other ones make sense, but not that one

var x : int %integer variable for number of guests var pizzatype : string var totslices : int loop cls put "Please enter number of guests: " get x put "Please enter your type of pizza (pepperoni, vegetarian or hawaiian" get pizzatype var slices : array 1 .. x of int %creates an array for asking for the number of slices for all the guests if pizzatype = "pepperoni" then for i : 1 .. upper (slices) put "Please enter how many slices you would like of pepperoni pizza, person", i get slices (i) totslices += slices (i) end for put totslices end if if pizzatype = "vegetarian" then for i : 1 .. upper (slices) put "Please enter how many slices you would like of vegetarian pizza, person", i get slices (i) totslices += slices (i) end for put totslices end if if pizzatype = "hawaiian" then for i : 1 .. upper (slices) put "Please enter how many slices you would like of hawaiian pizza, person", i get slices (i) totslices += slices (i) end for put totslices end if end loop I can't seem to get totslices to set equal to the sum of the slices array and then output the sum. Any ideas? |

Initialize "totslices" like gitoxa said. To do that, just add := 0 after the declaration (var totslices....). |

Yeah I figured that out, I felt so dumb once I figured it out. I'm so used to the default value of an integer being 0. Oh well, this is how one learns I guess. |
