void main()
{
int n;
void fib(int n);
clrscr();

printf("Enter any no.");
scanf("%d",&n);
clrscr();

printf("Hit any key to continue");
getch();
clrscr();
printf("Fibonacci of %d is \n");
fib(n);

getch();

}
void fib(int n)
{
static int x,y;
int temp;
if(n<=1)
{
x=0;
y=1;
}
else
{
fib(n-1);
temp=y;
y=x+y;
x=temp;
}
printf(" %d\n",x);

return;
}
