649 trouble

[MinionoiniM]

Ok, so its a school assignment.
Create a program that makes a 649 ticket, using single dimensional arrays.
Im pretty new to turing (first year) so no drawing, or any fancy font styles of anything.
So i dont know if my teacher made this up or not, but does everyone get modules? (just curious)
Any help is greatly apprieciated.

Oh yeah, i dont know how to post what i got so far as a picture, so ill just copy and paste.
Thanks again!

Turing:

var count : array 1 .. 49 of int := init (0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0) var die, counter, amount, counta : int counter := 0 counta := 0 put "how many times do you want to roll the die? " get amount loop     counter := counter + 1     loop         counta := counta + 1         randint (die, 1, 49)         count (die) := count (die) + 1         for i : 1 .. 49             put count (i), " " ..         end for         put " "         exit when counta = 6     end loop     exit when counter = amount end loop

Mod Edit: Remember to use syntax tags! Thanks

code:

1) use turing syntax
2) learn for loops they make life much easier and code easier to read
3)reset counta, you are currently trying to add to the counta after you pass your first ticket and you are reaching far more than 6
4) read 2-3 again.

..turing...syntax?
yes, i am VERY new to this
and i did use a for loop
how would you have six digits picked from one line?
thanks again

Turing:

var count : array 1 .. 49 of int var counter : int var counta : int

Don't do this.

[MinionoiniM]

ok so i took out the counta part and replaced it with a for loop, even though it does the same thing.
Still, how would you pick six digits from one line?

[DanielG]

use an array to store whether a number has been taken or not, and use a while loop (regular loop) until your randint returns a value that has not been taken. reset the taken array after every time you choose 6 values.

Thanks alot i got it!
But how can i ensure no duplicates?
When i put randomize before the randint(die, 1, 49) a value from 1 - 49 will become chosen six times (assuming i rolled once)
Thanks again!

Bad idea. While this might not be apparent in a small sized set, but as you require more numbers, the chance of randomly picking an eligible choice decreases.

Here's a better idea

randomize? Please read the documentation.

Quote:

Syntax randomize

Description This procedure is obsolete. It was originally used to produce a different sequence of random numbers each time a program executed. With current versions of Turing, the random number sequence is ?randomized? each time a Turing program is executed, eliminating the need for this procedure

On the similar note, randint is deprecated. Use Rand.Int instead.

Ohh, thats how you show turing code. Thanks mod =D
And hmm, i tried Rand.Reset, which works good actually. Thanks alot everyone =D
