What is it you are trying to achieve?[/b][/size] i am trying to achieve a calculator that displays the symbols. What is the problem you are having? i am having trouble with the not= operator Describe what you have tried to solve this problem <Answer Here> hey guys i need help for my program. I need to know why it is saying "operands of Boolean operators must be boolean." the part that says that is the : if symbol not= "*" or "/" or "+" or "-" then cls put "I'm sorry, you have entered an invalid symbol. Please try again." put "" end if i need help as to why it is saying this. Post any relevant code (You may choose to attach the file instead of posting the code if it is too long) <Answer Here> Here is my code : var num, num2 : real := 0 var symbol : string var sum : int := 0 locate (1, 28) put "C A L C U L A T O R" .. locate (3, 28) put "F U N C T I O N S :" .. locate (5, 1) put " MULTIPLICATION" .. locate (5, 25) put " DIVISION" .. locate (5, 44) put " ADDITION" .. locate (5, 62) put " SUBTRACTION" put "" loop put "Please enter your first number : " .. get num put "" put "Please enter your second number: " .. get num2 put "" put "Please enter your symbol. The symbol can only be (*) , (/), (+), or (-) " get symbol put "" if symbol = "*" then put "You have selected to input the multiplication symbol" put "" put "Your two numbers will now be multiplied" put "" put "Your new answer is now : ", num * num2 put "" sum := sum + 1 end if if symbol = "/" then put "You have selected to input the division symbol" put "" put "Your two numbers will now be divided" put "" put "Your new answer is now : ", num / num2 put "" sum := sum + 1 end if if symbol = "+" then put "You have selected to input the addition symbol" put "" put "Your two numbers will now be added" put "" put "Your new answer is now : ", num + num2 put "" sum := sum + 1 end if if symbol = "-" then put "You have selected to input the subtraction symbol" put "" put "Your two numbers will now be subtracted" put "" put "Your new answer is now : ", num - num2 put "" sum := sum + 1 end if if sum = 1 then put "You have 4 answers remaining." put "" elsif sum = 2 then put "You have 3 answers remaining." put "" elsif sum = 3 then put "You have 2 answers remaining." put "" elsif sum = 4 then put "You have 1 answer remaining." put "" end if if symbol not= "*" or "/" or "+" or "-" then cls put "I'm sorry, you have entered an invalid symbol. Please try again." put "" end if if sum = 5 then delay (1200) exit when sum = 5 end if end loop if sum = 5 then delay (100) cls put "You have no answers remaining." .. put "If you want to try this program again, please" put "close this window " .. put "and hit the run button." put "Otherwise, thank you for trying Wajih's Turing Calculator" end if
Please specify what version of Turing you are using <Answer Here i am using turing 4.1.1 |

That error means that a "boolean operator" (such as "OR") needs to have a boolean value (or an expression that evaluates to true/false) on both sides.

What this means is that to say "if symbol is NOT one of {+,-,*,/}" you have to say:
Note that you need to change from "symbol is not one of" to "symbol is not the first AND symbol is not the second AND symbol is not the third AND ..." . |
