times table

[Tallguy]

i'm doing a program to create a times table for a usr defined range this is what i have


%Alex van der Mout

setscreen ("graphics:600;500")

var number, math : int
put "What do you the table to up to? (max 12) " ..
get number
put ""
var height : array 1 .. number of real

for i : 0 .. number
put "" : 4, i ..
end for

put ""
for o : 1 .. number
put ""
put "" : 4, o
end for


how do i actually do the math for user defined?

Well, you are already keeping track of two variables, i and o, so use those in a nested for loop and output the multiplication.

Your multiplication will look something like...

code:

for i : 1 .. 5     put i * 5 end for

And your nested for loop will look something like...

code:

for a : 1 .. 10     for b : 1 .. 10         put "multiplication here"     end for end for

Also, your setscreen() call, height array, and math variable are all not being used, so you should remove them.

i thought of doing it a different way, but the spacing for the double + triple digits are really messed up

srry for how long it is

y do u always post thing before i do lol

'cause i'm special

Suggestions:

This is what you have

code:

put "" : 4, i ..

You're outputting spaces, and giving them a field width. Instead of that, play around with giving your numbers field width instead.


About your arrays, isn't the computer a calculator? Is it really neccesary to store all that information...


Did you even read the post from [Gandalf]? Nested loops are your friend.

[Tallguy]

yay i no but we have do do our arrays in this order,

"play around with giving your numbers field width instead."

i don't exactly know wat u meamn by this

[gitoxa]

Arrays in what order?

This is taken from the turing help doc

Statement Output Notes
put 121 : 5 bb121 % Width 5; b is blank

You're hard coding values into multiple arrays instead of doing simple multiplication, that's not a very good way of doing it at all.

code:

var num : int put "Up to what number? " .. get num for a : 1 .. num     for b : 1 .. num         put a * b : 4 ..     end for     put skip end for

This is much easier to understand, no?

Or do you mean that your assignment requires you to use arrays? Even so, you could assign your computed values to the appropriate element in the array and use that.

Or you can make your code more obfuscated with:

Turing:

var ans : int put "Up to what number? " get ans for x : 0 .. ans * ans - 1     locate (x mod ans + 1, x div ans * 4 + 1)     put (x mod ans + 1) * (x div ans + 1) end for

By the way, didn't someone already make a similar thread?

If arrays are required, use them and avoid multiplication (and if I was the teacher and I asked for arrays, using this is idea would be required for full marks):

Turing:

var num : int put "Up to what number?" get num var row : array 1 .. num of int for a : 1 .. num     row (a) := a     put a : 4 .. end for put "" for a : 2 .. num     for b : 1 .. num         row (b) += b         put row (b) : 4 ..     end for     put "" end for

Thanks for all the feed back, i used ur ideas and made my orignal better, now it is 39 lines instead of 400 <woot>, thanks a lot everyone

can i make it better?
