» » » Write a c program to generate fibonacci series without recursion

  • Fibonacci series starts from 0 ,1 and the next number should be sum of previous two numbers.
  • 0+1=1, so the next number in Fibonacci series in c program is 1. 0 1 1 
  • 0 1 1 2 3 5 8.. and so on.
  • Now let us see and c language example program on fibonacci series.


Fibonacci series in C language: 

  • First print 0, 1 by default.
  • and start from 2 and iterate upto n-1 using for loop.
  • inside loop assign n3=n1+n2;  
  • and ptint sum. printf(" %d",n3);  
  • Assign n2 value to n1. n1=n2
  • Assign sum to n2:  variable n2=n3;  


Program #1 : write a C program to print / generate fibonacci series up to n numbers.  Take input from user without recursion

  1. #include <stdio.h>
  2. #include <stdlib.h>
  3.  
  4. int main()  
  5. {   
  6. int n1=0,n2=1,n3,i,number;   
  7. printf("Enter the number of elements to be printed in Fibonacci series:");   
  8. scanf("%d",&number);   
  9. printf("\n%d %d",n1,n2);//printing 0 and 1  
  10.    
  11. for(i=2;i<number;++i)//Starts from 2 to given number-1
  12. {  
  13.   n3=n1+n2;  
  14.   printf(" %d",n3);  
  15.   n1=n2;  
  16.   n2=n3;   
  17. }  
  18. getch();  
  
Output:
