----------------------------------- kousha41564 Fri Dec 05, 2008 11:42 pm HELP PLZ , program being weird (turing) ----------------------------------- alright, this is a really simple caluclaotr, wiht a remember what the last equation equaled and re use that number kinda thing. at the bottom loop, i set it up so it only leaves the loop if the user types y or n. but no matter what they type the program asumes taht they would like to re use the last number. sorry if its confusin, its one of my first meaningfull programs, and was done for fun so :P var checklist : int := 0 var c1 : string var num1 : real var memory : string var num2 : real var answer : real := 0 var checklist2 : int := 0 loop if checklist2 = 0 then put "please enter the equation (include spaces between each part of the equation)" get num1, c1, num2 end if for counter : 1 .. 10000000 if checklist2 > 1 then put "please enter the equation (the first digit is asumed as ", answer, ")" get c1, num2 end if if answer > 0 then num1 := answer end if if c1 = "*" then answer := num1 * num2 put num1 * num2 end if if c1 = "/" then answer := num1 / num2 put num1 / num2 end if if c1 = "+" then answer := num1 + num2 put num1 + num2 end if if c1 = "-" then answer := num1 - num2 put num1 - num2 end if loop put "would you like to clear memory? (y/n)" get memory exit when checklist = 1 if memory = "y" then answer := 0 checklist2 := 0 checklist := 1 end if if memory = "n" then put "alright" checklist2 := 2 checklist := 1 end if if memory = "n" or memory = "y" then checklist := 1 end if put " " put "memory is ", answer end loop end for end loop ----------------------------------- DanielG Sat Dec 06, 2008 5:11 pm RE:HELP PLZ , program being weird (turing) ----------------------------------- this code has too many mistakes, first, your code would repeat twice in the 'y'/'n' part due to your exist when statement being too early (push it to later on in the loop). Also, the reason you are having problem with the memory erase is that you are not getting any input after the first time if checklist2 (the int you used to check if erase is needed) is 0. What I am writing now isn't really a mistake, but you should change anyway because it's bad coding. First, when you have multiple ifs where only 1 can occur, you should use elsif (or a case statement). Also, use boolean variables. Furthermore, don't use a huge for loop, you can use two loops one inside the other and the exit statement will only exit the inner one. ----------------------------------- A.J Sat Dec 06, 2008 6:17 pm Re: HELP PLZ , program being weird (turing) ----------------------------------- this code has too many mistakes, first, your code would repeat twice in the 'y'/'n' part due to your exist when statement being too early (push it to later on in the loop).

And, to add to that, you have redundant and 'weird' code...not that I am discouraging you or anything for ur first 'real' coding program, it is really good (the spacing and everything). Good Job! :D but look into the code and see if u can shorten it at parts (I dont want to give away anything else :wink:) ----------------------------------- kousha41564 Sat Dec 06, 2008 6:43 pm RE:HELP PLZ , program being weird (turing) ----------------------------------- thanks, but i cant quite figure out what youre saying, so could you fix it just so it works ? i will fix the if and elsif . i found out bout exit an hour ago :P and i still havent realized what boolean statements/variables are. i have no book or anything i am using to work this, the only way i wrote this is my past knwoledge of html and basic (not visiual). so could you show me what exactly is wrong ? ----------------------------------- Insectoid Sat Dec 06, 2008 6:51 pm RE:HELP PLZ , program being weird (turing) ----------------------------------- Boolean is 1 or zero (In Turing it's true/false). Works like any variable. Can be modified with boolean algebra. var bool : boolean := false %create the variable bool := bool & true %might be '&&'. performs the 'and' boolean operator. put bool %this should output false, because true and-ed with false = false For my example you need some rudimentary knowledge of binary & boolean algebra. Think of it as an integer that can only be 1 or 0. ----------------------------------- DanielG Sat Dec 06, 2008 7:02 pm Re: HELP PLZ , program being weird (turing) ----------------------------------- first you have this part if checklist2 = 0 then put "please enter the equation (include spaces between each part of the equation)" get num1, c1, num2 end if for counter : 1 .. 10000000 the problem with this is that the if checklist2 = 0 if only comes in the beginning, and needs to be moved into the main for loop another problem with you code is below: loop put "would you like to clear memory? (y/n)" get memory exit when checklist = 1 if memory = "y" then answer := 0 checklist2 := 0 checklist := 1 end if if memory = "n" then put "alright" checklist2 := 2 checklist := 1 end if if memory = "n" or memory = "y" then checklist := 1 end if put " " put "memory is ", answer end loop which should be changed to something like this: loop put "would you like to clear memory? (y/n)" get memory if memory = "y" then answer := 0 checklist2 := 0 checklist := 1 end if if memory = "n" then put "alright" checklist2 := 2 checklist := 1 end if if memory = "n" or memory = "y" then %_% you don't actually need this part, as it was include in your two past ifs checklist := 1 end if exit when checklist = 1 end loop put " " put "memory is ", answer ----------------------------------- Insectoid Sat Dec 06, 2008 7:09 pm RE:HELP PLZ , program being weird (turing) ----------------------------------- if memory = "n" or memory = "y" Is there any option other than 'n' or 'y'? This seems redundant to me, useless extra processing. ----------------------------------- kousha41564 Sat Dec 06, 2008 7:57 pm RE:HELP PLZ , program being weird (turing) ----------------------------------- insection what other option would there be ? its either yes or no and tahnks, could anyone give me some examples of uses of boolean in an program ? ----------------------------------- Insectoid Sat Dec 06, 2008 8:06 pm RE:HELP PLZ , program being weird (turing) ----------------------------------- If there is no other option, why have the statement at all? That's why I asked. If it's yes, or no, do this. But it HAS to be yes or no. So why even ask the computer? Just tell it to do whatever is in the block. Boolean is used to exit multiple loops, to control things that are either one option or the other. I used in it my adder program (but that is a very specific example). In an RPG, you can use boolean to represent true if an item has been used or false if not. You can use it to call a procedure, for example, if win = true then win_procedure else lose_procedure end if Further in your programming career, you will find you use boolean a lot. ----------------------------------- kousha41564 Sat Dec 06, 2008 8:07 pm Re: HELP PLZ , program being weird (turing) ----------------------------------- var checklist : int := 0 var c1 : string var num1 : real var memory : string := "ABC" var num2 : real var answer : real := 0 var checklist2 : int := 0 loop checklist := 0 if checklist2 < 1 then put "please enter the equation (include spaces between each part of the equation)" get num1, c1, num2 end if if checklist2 > 1 then num1 := answer end if if checklist2 > 1 then put "please enter the equation (the first digit is asumed as ", answer, ")" get c1, num2 end if if c1 = "*" then answer := num1 * num2 put num1 * num2 elsif c1 = "/" then answer := num1 / num2 put num1 / num2 elsif c1 = "+" then answer := num1 + num2 put num1 + num2 elsif c1 = "-" then answer := num1 - num2 put num1 - num2 end if put "would you like to clear memory ?
