你贴到 gist 上把。。。。
SIGSEGV 一般是内存访问越界 |

用 Markdown 排下版呗
```c // 代码 ``` |

进入调试模式跑一下看看？

看着蛋疼，可以排下版， v2 是支持 markdown 语法的，或者直接截 ide 的图也行

首先这代码编译就应该没办法过才对
楼主声明的函数是这样的 void input(int, int); 而定义又是 void input(int *count, int M) int 和 int *能一样？编译器没有给 error 么？ 我不知道楼主怎么使用以后会出 SIGSEGV ，光贴个代码有啥意义？我怎么知道你做了些什么操作导致程序有什么问题？ 举个例子 scanf("%s", wo[i].name); 看起来没问题楼主定义的 struct 中是这样定义的 char name[30]; 可是如果用户输入超过 30 个字符会怎么样？ 安全编码第一条，永远不要相信来自用户的输入 |
