C Program for Fibonacci Series using While Loop

C program for Fibonacci series up to given length.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

#include<stdio.h> #include<conio.h> main() {     int f1=0,f2=1,f3,i=3,len;     printf("enter length of the  fibonacci series:");     scanf("%d",&len);     printf("%d\t%d",f1,f2); // It prints the starting two values     while(i<=len)           // checks the condition     {         f3=f1+f2;               // performs add operation on previous two  values         printf("\t%d",f3);      // It prints from third value to given length         f1=f2;         f2=f3;         i=i+1;                  // incrementing the i value by 1     }     getch(); }

 

Output for Fibonacci Series Program

enter length of the fibonacci series:10
