true statement

[the_scott_mans]

i really need help with how to add up all the selections with the true statement. I am makeing a cash register and i was told to use the true statement thing well i was wondering what it is that i need to put for the true statement to get it to add up all of the selected true statements

i am also wondering how i can make it reconize a selection i have it laid out in list form, numbered, and indented. When i use the if statement it does not reconize it.

you're probably refering to boolean variable. It is used like a flag to mark stuff. For example:

code:

var total:int %counter var price:int %variable var word:string var tax:boolean %true/false flag for tax loop put "enter price" get price total := total + price exit when price =0 end loop put "add tax? y/n" get word if word="y" then tax := true else tax := false end if %now you can use that "tax" variable to check what the user selected from before if tax=true then put total+total*0.15 else put total end if

thanks that helps but how does it work with a list.

like all the items are numbered and you select the numbers then press done and it adds the tax and price of each selection.

make another array of boolean type with a coresponding numbers.

such as

tax(1) would keep true/false value about item(1)

so would i just put

if choice = "1" then
choice := true
else
choice := false
end if

if choice = "2" then
choice := true
else
choice := false
end if

etc.

and then

if choice = true then
put total+total*0.15
end if

or how would i get the computer to record all the prices then add them up
