写一个程序用递归法打印斐波那契数列？

参考以下代码实现：

#include<stdio.h>      
#include<conio.h>      
void printFibonacci(int n) // function to calculate the fibonacci series of a given number.  
{      
static int n1=0,n2=1,n3;    // declaration of static variables.  
    if(n>0){      
         n3 = n1 + n2;      
         n1 = n2;      
        n2 = n3;      
         printf("%d ",n3);      
         printFibonacci(n-1);    //calling the function recursively.  
    }      
}      
void main(){      
    int n;      
    clrscr();      
    printf("Enter the number of elements: ");      
    scanf("%d",&n);      
    printf("Fibonacci Series: ");      
    printf("%d %d ",0,1);      
    printFibonacci(n-2);//n-2 because 2 numbers are already printed      
    getch();      
}
