Question

write a program to print the first 10 number of fibonacci series

Answer 1

Hello friend...

INPUT:
// C program to print first n Fibonacci numbers

#include <stdio.h>

  

// Function to print first n Fibonacci Numbers

void printFibonacciNumbers(int n)

{

    int f1 = 0, f2 = 1, i;

  

    if (n < 1)

        return;

  

    for (i = 1; i <= n; i++)

    {

        printf("%d ", f2);

        int next = f1 + f2;

        f1 = f2;

        f2 = next;

    }

}

  

// Driver Code

int main()

{

    printFibonacciNumbers(7);

    return 0;

}

OUTPUT:
1 2 3 5 8 13

Hope this helps you...

Answer 2

Question:

Write a program to find the sum of 1st 10 numbers of Fibonacci series, i.e. 1,1,2,3,5,8,13…. Fibonacci series is such a series which starting from 1 and 1, and subsequent numbers are the sum of the previous two numbers.

Solution:

Language used: Java

public class FibSum

{

static void main()

{

int i,a=1,b=0,c;

System.out.println("Fibonacci series =");

for(i=1;i<=10;i++)

{

c=a+b;

System.out.print(c+" ");

a=b;

b=c;

}

}
