Ex.No:7b Fibonacci number Using Recursion

AIM:

        To write a program to find the ith Fibonacci number using recursion, given F(0)=0, F(1)=1.

ALGORITHM:

Step 1: Start the program

Step 2: read num

Step 3: f <- fibo(num)

Step 4: print f

Step 5: Stop

Step 1: fibo start

Step 2: If n<=1

Return 1

     Else

Return fibo(n-1)+fibo(n-2)

PROGRAM CODE:

#include<stdio.h>
#include<conio.h>
void main()
{
int num,a;
printf("nEnter the number");
scanf("%d",&num);
a=fibo(num);
printf("nThe fibonacci of the number %d is %d",num,a);
getch();
}
int fibo(int n)
{
if(n==0)
return(0);
if(n==1)
return(1);
else
return fibo(n-1)+fibo(n-2);
}
OUTPUT:

fiborec

RESULT:

                    Thus the C program to find the ith Fibonacci number using recursion is written and executed successfully.
