Are you sure that b can be exactly 4 million with that sequence?

well, it can't be exactly 4 millions

Do that until b is less than 4 million

but the exercise tells to sum numbers till the actual number reaches 4 million

oh okay

But print b after counting on it

so i'll change the loop condition

What was the first one?

<=?

Show the exercise question xD

4 millions

You're getting confused

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

4 millions

Is there a <= or a <?

oh wait, i need to do only even numbers

well is not a problem, just have to put an if

oh wait, i need to do only even numbers

That's just an if

well is not a problem, just have to put an if

Yea

oh values don't have to exceed 4 millions

is there a way to put a gap?

Print b after you define it

Try this way

b = b+a Cout<<" "<<b;

wait 1 moment

wait

so

So

b+a instead a+b? xD

isn't that the same?

It's literally the same thing

isn't that the same?

Yea

well, so it's the same as before xD

You have to print b after doing b = a+b

oh

b = b+a Cout<<" "<<b;

.

before a= b-a

same thing as before, maybe i have to do 2 loops

Do this, the cout has to be the last statement

Of the loop

while (b<=4000000) { b=b+a; cout<<" "<< b ; a=b-a; }

this is my loop

before it was "cout<<" "<< b ;" after a=b-a;

while (b<=4000000) { b=b+a; a=b-a; cout<<" "<< b ; }

try this

but wait, i have to calculate only even numbers, let me see if something changes

i did that before, still gets to 5.5 millions

both should be the same, though

but wait, i have to calculate only even numbers, let me see if something changes

it's an if

i did that before, still gets to 5.5 millions

let me try that on my computer, wait a minute

kk

it's an if

but maybe with even numbers it stops to 4 millions, who knows ahah

i knew it

it stopped to 3.5 millions

while (b<=4000000) { b=b+a; a=b-a; if (b%2==0) cout<<" "<< b ;

that's it

thank you a lot btw @CristopherCerasuoli

thank you a lot btw @CristopherCerasuoli

oh i did practically nothing

ahah, well, u helped me

it's just that i haven't programmed for a lifetime, i'm probably younger than you

i would have never done it lonely

how old are u?

15 lol

me2

by the way, i'm learning c++ by "Project euler" website

someone told me that it's good for learning c++

never heard about that

there are a lot of maths problems, that u have to solve with c++ programming

that's where i got those exercises

now i have to find prime factors of a number, i'll ask you if i need some help ahah

rip

Just use yafu

what's that?

a program to factor numbers

Just copy the source code and done

nah ahah

i want to make it by myself

i'm doing those exercises just for learning c++

i'm doing those exercises just for learning c++

I got stuck at C++ after OOP part.. my brain hurts

ahah

I am like what is abstraction? What is encapsulation? inheritance is fine, but stucked at polymorphism
