help - calender

[whoareyou]

What is it you are trying to achieve?
To create a user-generated calender using repetition commands.

Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)

Turing:

var nodays:int var day:string loop put "How many days are there?" get nodays if nodays > 31 then put "Please try again!" end if exit when nodays = 31 or nodays = 30 or nodays = 29 or nodays = 28 end loop loop put "What day does the month start on?" get day if day not = "Monday" or "Tuesday" or "Wednesday" or "Thursday" or "Friday" then

Please specify what version of Turing you are using
4.1.1

You forgot the part where you're supposed to tell us what problem you're having. Without that, we have no idea what you want help with.

i tried testing that code that i have there before i move on, but it says operands of bollean operators must be boolean and "Tuesday" is highlighted.

[Tony]

what does

code:

"Tuesday" or "Wednesday"

evaluate to?

its a string, so if the user inputs Tuesday, then it should store than in "day"

[Tony]

I meant as appears in your code

code:

if "Tuesday" or "Wednesday" then    put "what is this?" end if

[whoareyou]

if the user enters monday, or tuesday, or wednesday ... etc, then it should store it in the variable day.

if not, i have to add in that it is invalid, and it should repeat that part until the user enters one of the 7 possible values for days.

That's not the way conditionals work. You need to compare each individual day to the input.

code:

if day != "monday" and day != "tuesday" and...

[Tony]

what's strange is that boolean operators were used correctly above

code:

exit when nodays = 31 or nodays = 30 or nodays = 29 or nodays = 28

[whoareyou]

maybe its because i used a string. i think i need to change it to an integer, and associate each day with a number.

What Tony is hinting at is that that condition isn't doing what you think it is. The error message is actually pretty direct here. It's telling you that the operator "or" only works on booleans. That means that the value to the left and the value to the right must BOTH be booleans.

When Turing looks at your code file, it sees it like this:

if - starting an if-statement, good
day not= "Monday" - conditional, returns boolean, good
or "Tuesday" - what's that supposed to mean?!

What you really mean is this:
if not ( day = "Monday" or day = "Tuesday" or ... ) then

This gives you the logic you are after. First, you compare the value in day against each of "Monday"..."Friday"; if it matches any of those values, then the contents of the parenthesis returns true. You then negate that result with "not" and end up with true if and only if the value in day is NOT one of "Monday"..."Tuesday".

THAT WAS CORRECT! :O
Thank you!

So by using your technique, my code now works and looks like this. However, it is not finished. If i run into more problems, i'll be sure to post back here!

Turing:

var numberof:int var day:string loop put "How many days are there?" get numberof if numberof > 31 or numberof < 28 then put "Please try again!" end if exit when numberof = 31 or numberof = 30 or numberof = 29 or numberof = 28 end loop loop put "What day does the month start on?" get day if day = "Monday" or day = "Tuesday" or day = "Wednesday" or day = "Thursday" or day = "Friday" then else put "That is not a valid day!" end if exit when day = "Monday" or day = "Tuesday" or day = "Wednesday" or day = "Thursday" or day = "Friday" end loop

Very long just for the beginning!

[whoareyou]

how should align the numbers so that they appear under each appropriate day ?

[Tony]

Using spaces. Documentation for put might have a shortcut for that, but it's the same idea.

[whoareyou]

My code so far:

Turing:

setscreen ("text") var nodays:int var day:string var daycount:int:=0 loop put "How many days are there?" get nodays if nodays > 31 or nodays < 28 then put "Please try again!" end if exit when nodays = 31 or nodays = 30 or nodays = 29 or nodays = 28 end loop loop put "What day does the month start on?" get day if day = "Monday" or day = "Tuesday" or day = "Wednesday" or day = "Thursday" or day = "Friday"  or day = "monday" or day = "tuesday" or day = "wednesday" or day = "thursday" or day = "friday" then else put "That is not a valid day!" end if exit when day = "Monday" or day = "Tuesday" or day = "Wednesday" or day = "Thursday" or day = "Friday" or day = "monday" or day = "tuesday" or day = "wednesday" or day = "thursday" or day = "friday" end loop put skip var d1, d2, d3, d4, d5, d6, d7 : string d1 := "SUN" d2 := "MON" d3 := "TUES" d4 := "WED" d5 := "THURS" d6 := "FRI" d7 := "SAT" put d1, " ":10, d2, " ":10, d3, " ":10, d4, " ":10, d5, " ":10, d6, " ":10, d7, " ":10 if day = "Monday" or day = "monday" then for i: 1 .. nodays put " ", i:10.. daycount += 1 if (daycount mod 7 = 0) then put "" daycount := 0 end if end for end if

I have it set up so that it will run when i enter 30 days and the start date is on monday.
however, the numbers won't allign under the right date properly.

i dont underestand how i can use spaces, because then each number will get spaces and it will go off the calender.
also, it won't go onto the next line once it reaches saturday.
