编写并测试一个函数Fibonacci()，在该函数中使用循环

#include <stdio.h>
long Fibonacci (int );
int main(void)
{
 int n;
 printf("Enter an integer (q to quit):\n");
 while (scanf("%d", &n) == 1)
 {
 printf("The term %d of Fibonacci sequence is %d\n", n, Fibonacci (n));
 printf("Enter an integer (q to quit):\n");
 }
 printf("Done.\n");
 return 0;
}
long Fibonacci (int n)
{
 int n1,n2,temp,i;
 if(n >2)
 for(n1=1,n2=1,i=3; i<=n; i++)
 {
 temp = n1 + n2;
 n1 = n2;
 n2 = temp;
 }
 else n2=1;
 return n2;
}
