need a program

miladerfanian

hi to all
I need a program in pascal to create this numbers with array.
this is my university project.
plz help me.

8 8 8 8 8 8
6 6 5 5 5 8
6 3 3 2 5 8
6 3 1 2 5 7
6 4 4 4 4 7
6 7 7 7 7 7

this is too important for me.
tnx alot

Do you need to compute this matrix and display it or just want to incorporate it in your code ? Be more specific.

I need just compute this matrix and display it.

OK, I need to know the initial data + the algorithm you want to apply

: OK, I need to know the initial data + the algorithm you want to apply

my problem is I don't have any algorithm for this.
just I know that 1 repeat one time.2 repeat 2 time and ...

11 11 11 11 11 11 11 11 11 13
11 9 8 8 8 8 8 8 11 13
12 9 6 6 5 5 5 8 10 13
12 9 6 3 3 2 5 8 10 13
12 9 6 3 1 2 5 7 10 13
12 9 6 4 4 4 4 7 10 13
12 9 6 7 7 7 7 7 10 13
12 9 9 9 10 10 10 10 10 13
12 12 12 12 12 12 13 13 13 13
[/code]

(This isn't tested at all, just a thought)
Couldn't you use an equation such as:
[code]
count := 0;
For i := 1 to n do
total := total + i;

BoxWidth := Sqrt(Total);
BoxHeight := Sqrt(Total);
[/code]

Basically you would add then lenths of all the numbers together (as if they were in a straight line). Also, we know that when wrapped up they will form a square and to find the Width/Length of a square from the area, we take the square root of the area, therefore giving us how long the sides will be.
right??
I could be way off in left field here, but this idea made sense in my messed up head. lol.

In the example above, the numbers all add up to 91.
The Sqrt(91) ~ 9.54
Therefore, we expect it to have about 9 1/2 sides. As we can see it does have a square of 9x10 with a 0.04 leftover
Then we can just start drawing from there.

Hope this helps.

This would do... code could be optimized and documented more, I'm just too lazy today.... If you need more explanation just ask.

thank you bro.
I write this in turbo pascal 7.0.
compile has no error but when I run it and error shown:division by zero.
can you help me about this?

Works fine with my TP7, but I got the patched crt unit. Try to run it under dosbox ( www.dosbox.com ), see what happens. I suspect is the crt unit what is responsible for this.
