In C Write a function nthFib that takes an integer argument

In C

Write a function “nthFib” that takes an integer argument N and returns the Nth fibonacci number. You can learn more about the fibonacci series by googling it but the first 10 terms are: 0,1,1,2,3,5,8,13, 21, 34.

Solution

#include<stdio.h>

int nthFib(int N){

   if(N<0)
   return -1;
   else if (N==0)
   return 0;
   else if (N==1)
   return 1;
   else if (N>1)
   return nthFib(N-1) + nthFib(N-2);
}
int main()
{
   int num=nthFib(5); //Change the argument to get different Nth number
   printf(\"5th number of Fibonacci series:\",num);
   return 0;
}
