PLEASE HELP ME RIGHT AWAY! a small but important question

scottyrush13 · **Posted:** Thu Nov 04, 2004 4:31 pm

im new to turing and just taking a turing course in my highschool and i got a question that im not sure how to do, i have it done up to a point and i dont even know if thats right...heres the question:

"Write a program that simulates the rolling of two dice. The program should use randint to roll the first die, and should use randint again to roll the second die. The sum of the two values should then be calculated. Note: Since each die can show an integer value from 1 to 6, then the sum of the two values will vary from 2 to 12 with 7 being the most frequent sum and 2 and 12 being the least frequent sums. Your program should roll the two die 36, 000 times. Use a one dimensional array to tally the numbers of times each possible sum appears. Print the results in a tabular format on the screen."

if anyone can help me by telling me a)what to do, or b)write the program and then copy and paste it, i would really appreciate it

thanks to whomever might reply!

It's against unofficial policy for those who frequent these boards to simply provide answers. This is cheating. Already there have been significant complaints about this levied against this site. We don't want instructors banning students from visiting, because this site can be a tremendous help for those open to learning.

With that out of the way, do you understand:

How to use randint to get a random number in a certain range (1-6 in this case)?
What an array is?
How to create a one-dimensional array?
How to put values into an array?
How to get values out of an array?

I invite you to look at the Turing Tutorials forum for answers to these questions.

Random Numbers
Arrays

Since this is your 1st post i will be nice. on this site there are some rules and guid lines about making posts and sicslky post in this section. To start with the subject of your post should not be "i need help" or "i have a question" we know this other wise u whould not be posting in truing help:p it also makes it harder for poleop trying to find awsers when the subjects are like this. in addtion using all caps is a bad idea online at any time.

Now on the content of your post......ushely u will get 100 times more help and 100 times less flaming if u post some code in witch u tryed to slove the pobrlem. This makes it so a) we know u are not just trying to get us to do your home work and b) it makes it easyer to help b/c it shows what level u are at and gives us somting to wrok with.

Now for the question:

what you are going to need to do is make an array that is the size of all posable sums, then u make a for loop and in it u first add together two ranint comands that will return a number from 1 to 6 each. next u add one to that index of the array (so if the sum was 5, then the idex to add 1 to whould be 5). Affter that u will have an array that has the values of the sums that u just need to print out using a for loop.

P.S. make shure to set all the elements of the array to 0 1st.

EDIT: dang fast posting wtd :p

read me
to add to wtd's list, you'll need to know how to use a for loop as well.

i understand how to use randint and that stuff and i know what an array is but i dont know how to add or get values from the array...but i will read the link you provided, and i never meant to take someones answer and use it directly, i wanted to look at HOW they added values to an array and how they outputted the values

code:

for i: 1..10
put myArray(i), " "
end for

that whould print the array, the addtion to it whould work much the same way....[/code]
