Fibonacci series Program in C | C program to generate Fibonacci Series up to given Number

Spread the love

Description :

A series of whole numbers in which each number is the sum of the two preceding numbers. Beginning with 0 and 1, the sequence of Fibonacci numbers would be 0,1,1, 2, 3, 5, 8, 13, 21, 34, etc.

formula to calculate Fibonacci Series n = n(-1) + n(-2), 

where the n(-1) means “the last number before n in the series” and n(-2) refers to “the second last one before n in the series.”

Program : 

  1. #include<stdio.h>
  2. int main()
  3. {
  4.         int i,j,k,num;
  5.         printf(“Enter any positive Number : “);
  6.         scanf(“%d”,&num);
  7.         /* because No Fibonacci series for Negative
  8.          * Numbers,. please enter more than 0. ex: 1,50,100.
  9.          */
  10.         if(num > 0)
  11.         {
  12.                 printf(“Fibonacci series is :”);
  13.                 i=0;
  14.                 j=1;
  15.                 printf(” %d %d “,i,j);
  16.                 k=i+j;
  17.                 while(<= num)
  18.                 {
  19.                         printf(“%d “,k);
  20.                         i=j;
  21.                         j=k;
  22.                         k=i+j;
  23.                 }
  24.         }
  25.         else
  26.         {
  27.                 printf(“No fibonacci series for Negative Numbersn);
  28.         }
  29.         printf(n);
  30. }
