Question

Okay does ne1 know how to do fibbonaci series in C++ can anyone explain me the logics behind them need desperate help
!!!!

Answer 1

This is the definition of the Fibonacci Sequence.

\[F_0 = 0, F_1 = 1\]\[F_{n+2} = F_{n+1}+F_n, n \geq2\]

Answer 2

This is what we call a Linear Recurrence. The n-th term of the sequece depends on some linear combination of the terms before it.

Answer 3

hoping u know C++

Answer 4

Using the formula, for the next term we would get:
\[F_2 = F_1+F_0 \iff F_2 = 1+0 = 1\]
the next term would be:
\[F_3 = F_2+F_1 \iff F_3 = 1+1 = 2\]
so on and so forth. The sequence looks like:

0, 1, 1, 2, 3, 5, 8, 13, ....

No i dont know C++ =/

Answer 5

what are you asking... what those terms mean?

Answer 6

or which one is fibbonaci

Answer 7

it looks like he's doing a project in C++ where he has to code the F. Sequence.

Answer 8

the fibbonaci is
A
AB
ABC

Answer 9

...or maybe not? now im a little lost.

Answer 10

oh you are trying to create a code for fibbonaci's sequence

Answer 11

yes!!!!!!!!

Answer 12

he's trying to create a C++ code to show what fibbonaci sequence is doing

Answer 13

do you have a way to create some sort of string?

Answer 14

no i got this code from a friend i want to know how would it execute!!!

Answer 15

...i thnk that code might spit out the nth Fibonacci number? it looks like its going to ask you for a number, and store it in 'a'

Answer 16

hey outcast do u know C++

Answer 17

not really i've done a little coding

Answer 18

then its going to cycle through values of i until i is bigger than a, then it will stop? i dont know >.<

Answer 19

yes joe but ow does it WORK????

Answer 20

joe math is correct he's asking for n and storing it as A

Answer 21

for(i=1i<=a) is basically counting by integers

Answer 22

all the wya to anything <= a

Answer 23

and then i++

Answer 24

so basically do you understand for statemtns?

Answer 25

it's a loop that continuously evaluates your expression until you hit a

Answer 26

so you have for(initial expression, conditional statement, evaluation (i++)

Answer 27

if i was making a program for the Fib numbers, i would cheat and use the closed formula lol <.< recursion is for noobs! lolol jk

Answer 28

however i always used if statements when using for statements

Answer 29

it'd also help to not use word lol

Answer 30

Notepad++

Answer 31

as it will keep track of what is within brackets

Answer 32

becaue technically this file would not run because he has syntax errors within it

Answer 33

he's missing a bracket somewhere
