#include <stdio.h>
int main()
{
    int i,a=2,b=3,c;
    float sum=1,term;
    for(i=2;i<=20;i++)
    { printf("(%d,%d)\n",b,a);
      term=1.0*b/a;
      sum=sum+term;
      c=a+b;
      a=b;
      b=c;
    }
    printf("%f\n",sum);
    return 0;
}实际上就是斐波那契序列的后项除以前项,但没有2/1这一项,所以sum初始值设为1,另外整数除以整数结果是整数,所以用1.0乘变为实数
