I'm trying to code out a simple program to display the first 20 numbers of Fibonacci's Number (1,1,2,3,5,8,13... *1+1 =2.. 2+1=3.. 3+2=5.. 5+3=8.. etc...*) Can anyone tell me why it isn't adding properly> I can get the program to display 1,1,2,3,5,8.. but then the rest isn't working properly. ^^;; This is what I have so far:
Code: Select all
var number : int := 1
var sum : int
var sum2 : int
sum := number + number
sum2 := number + sum
put number,", ",number, ", " ..
put sum, ", " ..
put sum2, ", " ..
for i : 1 .. 20
number := sum + sum2
sum2 := sum2 + sum2
put number , ", " ..
end for[code]

what exactly isn't working after? Are the numbers not displaying? Are they higher than they are supposed to be?

everything is displaying properly but the out come isn't right.
I'm trying to get the numbers to display as:
1, 1, 2, 3, 5, 8, 13, 21, 34, etc..
but it is appearing as :
1, 1, 2, 3, 5, 9, 17... blah blah blah.
The adding of the variables is working correctly.

number := sum + sum2
sum2 := sum2 + sum2
That's where the problem lies. I would use this type of formula:
sum1 := sum1 + sum2
sum2 := sum1 + sum2
print sum1, ", ", sum2
Say you start off with both value's being 1.
The first loop through would give you 2, 3
The second loop through would give you 5, 8
The third loop through would give you 13, 21
(at least to my knowledge, this is all done in my head at the moment)
Try using that formula in place of what you are already using. Hope this helps
