still cannnot figure this out

I am trying to get this fibonacci to work but it is giving me the wrong answers. please help

#include <stdio.h>

int cal_fibonacci (int d);


void main(void)
{
int b,c;
printf("Please enter a WHOLE number:\n");
scanf("%d",&b);
c=cal_fibonacci(b);
}

int cal_fibonacci (int d)
{
int f1;
int f2;
int fnew, temp;
int x;

for(x=1;x<d;++x)
{
while (x<3)
{
printf("%d" "1",x);
printf("F1=1");
printf("F2=1");
x+=1;
}
fnew=f1+f2;
printf("%d" "%d",x,fnew);
f1=temp;
f2=f1;
f2=fnew;
}

}

Okay, I explained why your program won't work already and even gave you the solution. The Fibonacci sequence is a simple but important one, you can find a Fibonacci number in a great many places in nature. Here's the sequence:

1 1 2 3 5 8 13 21 34 55 89 etc...

The next number in the sequence is the sum of the current number and the number before it. So here's your logic structure, you can build your program from this.

                | n <=  1:  1
Fibonacci(n) =  | n =   2:  1
                | n >   2:  Fibonacci(n - 1) + Fibonacci(n - 2)

If you want to see an implemetation of this in C, view my reply to your previous post.
