《带你学C带你飞》动动手作业题S1E31执行错误为什么

本帖最后由奥普瓯江于 2017-9-22 11:08 编辑

题目是

为什么我写得程序执行不了，第一个问题是，洗牌时执行选项失败没有反馈，还有就是洗牌“ad”指针数组第1个是空字符我也不知道问什么，还麻烦大神给予解答谢谢

#include<stdio.h>
#include<stdlib.h>

1，d++ i++ g++;请放到后面；
2， Y/N 再次接收时
while(getchar()!='\n') //#清空键盘缓冲区数据
continue;

3，fapai() ; xipai(); 就合成一个洗牌就好了。

4，随机数有重复（我这里也没有解决）

参数代码：
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define MAX 1024
#define NAX 14

};

还有一个额外的提问就是为什么要清空键盘缓冲区数据，我在往上找了一下只知道使用的方法了，但是没有理解，还麻烦能否给推荐一下或者给解释一下谢谢

getchar() 获取字符啊。能不消除

明白了谢谢，他是获取了第二个字符\n
