C++ :: Calculate The Nth Number In Fibonacci Sequence
Feb 28, 2013I was trying to create a code to calculate the nth number in a Fibonacci sequence, when the nth number is entered interactively.
View 4 RepliesI was trying to create a code to calculate the nth number in a Fibonacci sequence, when the nth number is entered interactively.
View 4 RepliesThe next code is right. I mean it works. It gives the sequence of fibonaci numbers ...
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int fibo(int pos) {
if(!pos)return 0;
if(pos==1)return 1;
[Code] .....
But.... when I change the lines:
Code:
int r1=fibo(pos1);
int r2=fibo(pos2);
int r=r1+r2;
For the lines:
Code:
int r=fibo(pos1)+fibo(pos2);
It doesn't work right. Apparently it should work the same.
I need to implement the fibonacci number sequence. Here is an example output of the program:
Server:Waiting for connection
Server:Receive connection from client
Client:10
Server:Print 10 Fibonacci
Server:1 1 2 3 5 8 13 21 34 54
Client:1 1 2 3 5 8 13 21 34 54
if Client send value of 5, the output would be 1 1 2 3 5
When ever I enter a value higher than 10, my out put looks like this
How many numbers are in the Fibonacci Series? 20
0 0 0 0 0 0
0 0 0 0 34 21
13 8 5 3 2 1
1 0
Press any key to continue . . .
This is what I got when I entered the value 20.
As you can see, it will only display up to the 10 term of the Fibonacci sequence
I'm trying to get the output to look like this:
4181 2584 1597 987 610 377
233 144 89 55 34 21
13 8 5 3 2 1
1 0
Here is my code:
#include <iostream>
#include <iomanip>
using namespace std;
#define SIZE 20
void Fibonacci( int );
int main( ) {
cout << "How many numbers are in the Fibonacci Series? ";
[code].....
I made a fibonacci series with label above it now how to put the label after the first layer because as you can see in the screenshot the label is continuous.

Q) How to do Fibonacci sequence?
I'm trying to make a fibonacci sequence with some user inputs. I'm using arrays for this, the user inputs are for the Nth term and the starting number (as in the number in front of 0).
My problem is that when the program runs it's an infinite loop which constantly prints the starting number. Which, I think, means that my WHILE loop isn't coming to an end and my 'count' variable isn't increasing.
#include <iostream>
using namespace std;
int main() {
int start;
int term;
cout << "Input a starting number for the sequence: ";
cin >> start;
cout << "
Enter the Nth term for the sequence to reach: ";

What is the most efficient way to calculate Fibonacci. Is it recursion with memorization, is it iteration or is there another approach?
View 1 Replies View RelatedWrite a C program that calculates the sum and average of a sequence of numbers. Assume the first number specifies the number of values remaining to be entered. If the first number is less than 1, then the program should display an "Invalid Entry ... Please enter a positive number." message.
THIS IS HOW IT SHOULD COME OUT...
Enter the number of values to process 0
Invalid Entry ... Please enter a positive number.
Enter the number of values to process 3
Enter 3 numbers:
1
2
3
Sum: 6
Avg: 2
THIS IS THE CODE I HAVE SO FAR...

Is it even possible to store the 100th Fibonacci number (beginning with the numbers 1 and 1) into a variable? I know the number is pretty huge, and wondered if there is a data type to hold a number that big.

I have to write a program to find the nth number of the Ulam numbers.
It's a bit complicated to explain what an Ulam number is but Wolfram explains it very well here: [URL]
I have to find the nth Ulam number but I don't know what I have to do to get that. My program gives me all the Ulam numbers from a range of 0 to n.
What I want the program to do is tell me that the 49th Ulam number is 243.

I am trying to write a program that checks whether the number is in sequence(as in if the numbers are in order it is a sequence). Ex: If the numbers are {1,2,3,6,7,8,9,10,11,13,15,17,20,21}, then, the underlined parts are a sequence. Now i want to find
1) the no of sequence in the array(in the above it is 3 )
2) the longest sequence (7to 11 which is 5).

I have to made a programme which will search for given number and it must work in O(log(n)). The problem is that this programme beside finding this number have to find how many times this given number is used in this sequence.
Sequence is from lowest to highest only one possibility to use binary search algorithm
For example when we have squence
-1 -2 3 3 3 3 4 5 6 7 7 8 9 9 9 9 10
The numbers we need to search are
1 , 3 , 7 , 9 , 11 , 12
The answer is
0 , 4 , 2 , 4 , 0 , 0
So we need to find the sum of used number in sequence.
I have written algorithm Code: int start = 0;
int end = sequencelenght - 1;
int mid = 0;
/// Binary serach
while (start<=end) {
int mid=(start+end)/2;
if (sequence[mid]==givennumber) {
[Code] .....
As u see i search for given numer with binary with O(log(n)) but when i have to sum the duplicates the only good way i see is using loop to right and left but this have got log(n) specification (because when sequence would be for example 7 7 7 7 7 7 7 7 7 and given number to search will be 7 this will be O(n) loop).
How would look the most optimal algorithm look for this exercise? I mean O(log(n)) the fastest algorithm....
I was doing a side project from my textbook about finding the mode, which is the number that occurs most often in a sequence of numbers. I racked my brain on this for an embarrassing amount of time and finally came up with this, which I think works but for some reason I still feel like I'm not done.
#include "stdafx.h"
#include <iostream>
using namespace std;
void mode(int *, int);
void main() {
const int NUMBERS = 15;
int list[NUMBERS] = {99,73,56,14,28,42,93,64,51,26,56,16,38,81,98};
mode(list,NUMBERS);
[Code] ....
Console Output:
Final Mode 56

I have a program that allows the user to enter a specific number of test scores. Based on these test scores, the program should display the average score and calculate how many of the scores were above 90. I have most of it done but I'm having trouble figuring out how to calculate the number of scores that were above 90. What am I doing wrong?
This is my code:

So how would find say write a program to calculate Pi to N number of places?
I'm trying to write a code to calculate the minimum number of coins needed to cover a change. It works fine but i want to display a message telling the user to try again if they type something that's not a number or a negative number. But it's not working. When i type a negative number, the program runs normally and displays a negative value of coins instead of showing the message. And when i type something that's not a number, the program just keeps showing a lot of zeros nonstop. And when i try to compile it with 'unsigned float' instead of just 'float' i get errors.
Code:
#include <stdio.h>
