A recursive function to calculate the nth Fibonacci number appears below. Insert statements before both return statements to print out both the parameter and the result.
int fib(int n)
{
int result;
if (n <= 1)
return(n);
else {
result = fib(n-1) + fib(n-2);
return(result);
}
}
Then write a main program that uses the function to calculate the 4th Fibonacci number, i.e., n = 6. You will submit a program listing (properly commented) and your output.
