c program to print febonacci series

Description

 This program prints the febonacci series upto the given limit. A febonacci series is generated by successively adding the last two numbers in a series. This program checks the condition that the value for n is greater than 1. Then the program uses while loop to print the febonacci series.

Example

Febonacci series with linit 7, starting with 0

0, 1, 1, 2, 3, 5, 8

Program

#include<stdio.h>

#include<conio.h>

void main()

{

clrscr();

int f1=0,f2=1,f3,i=1,n;

printf("Enter the value of n");

l:

scanf("%d",&n);

if(n<2)

{

printf("n should be greater than 1\n");

goto l;

}

else

{

printf("\n %d\n%d",f1,f2);

while((i<=(n-2))

{

f3=f1+f2;

printf("\n %d",f3);

f1=f2;

f2=f3;

i++;

}}

getch();

}
