这是什么玩意？描述一下，好理解一点。

[亮剑_]

楼主:
最好有一些注释说明啊

[Smartdoggie]

哈哈哈哈

[jack_wq]

楼主想说明什么？

乱死了，格式清楚一点嘛。如果这个就是你的源代码，那么不用细看也知道有问题，例如：
# include "sting.h"
//这个是自定义的头文件吗？

又如：
void outprint(head)
{ struct modi *head;
struct modi *p
printf("category Commodity stock sellnumber profit\n")
p=head;
//这里有俩个句子结束都没有分号

又如：
void exitfuc()
{ exit;}
char outmodi;
printf("Welcome you! Now, please input the commodity:\n");
//第三排后的语句属于函数exitfuc吗？

UP

[Bandry]

唉

[hlnpro]

晕~~~~~~~~菜

[hellobcb]

这分不好赚啊！除非给500分，帮你看看！

[skywater]

Oh my god!

[ShiChao]

都看不出这个程序是干什么用的啊
