Need help Fibonacci series C language

[Venum]

I want in depth idea on displaying the next three numbers in the fibonacci series. it doesnt matter if its a long series of fibo numbers as long as the three maybe starting numbers is printed out.

What do you mean with "without inputing any integer but instead directly calculates the next three numbers"? The next three numbers to what?

 

The general form for a fibo series is starting with the base cases:

fib(0) = 0fib(1) = 1 And getting the next elements with:fib(n) = fib(n-2) + fib(n-1), n > 1

So if you want to get the first 10 fibonacci numbers:

int sequence_sz = 10; //first 10 fibonacci numbersint fib[sequence_sz];if(sequence_sz > 0){     fib[0] = 0;     if(sequence_sz > 1) fib[1] = 1;     for(int i = 2 ; i < sequence_sz ; i++) fib[i] = fib[i-2] + fib[i-1];}

Could you elaborate on what you are trying to achieve?

@wolfsinner's post is indeed the general form of the Fibonacci sequence, if you mean something else you will have to formulate it in a different way so it is understandable for the people trying to help you.

I have seen some formulate a code that ask a user to input a number. i wanted to omit that option and directly calculate the asked output.. im so confused T.T

The number is needed for input, so that you can choose what you want to output (e.g. the first 100 fibonacci numbers).

If you omit that, the output will be the same all the time.

If you are still confused you might want to read this: https://en.wikipedia.org/wiki/Fibonacci_number

There is not an obvious end of the Fibonacci sequence. That is why most of the time the user will be prompted to manually submit an end. What they say is the end, e.g. 3, represents the third number in the Fibonacci sequence. The program will then calculate all the numbers in the sequence until 3 (including, I assume). If you not set an end, it will go on until it hits an error because the number you're trying to store in the data type you used is too large.

You can hard code the end into your code, if that is what you mean, I can not give some code examples right now as I am on a mobile device, but here is the hard coded end:

for (int i = 1; i <= 3; i++)

If some of what I said is incorrect, please improve me

Oh, the code does not seem to be displayed properly.

for (int i = 0; i <= 3; i++)

[Maximation]

Wow, why does it still not display properly? Oh well, you'll have to ask someone else for some code snippets.

Code tags brah

Code tags brah

Tapatalk does not want to let me use code tags... Oh wait.. Ugh I am so stupid

for (int i = 0; i <= 3; i++)

There you go.

Here you go.. This will print forever

 

C++

#include <iostream>using namespace std;int a = 0, b = 1, c = 0:void main() {        cout << 1 << endl;	while(true){		c = a + b;		a = b:		b = c;		cout << c << endl;	}}
