我输入5，输出0，1，2，3，4，5是对的
应该输入-5，输出为0，-1，-2，-3，-4，-5  可只输出了-5  ？？？？？

忘打了不好意思 ，应该是if（i<b）{
                                                        printf()
                                                        i++;
                                                        count(i);
                                                    }
    可还是输入正数时可以得到正确结果，输入负数时就只得到那一个
