为什么scanf函数无法结束输入
scanf 函数无法结束输入，一直可以输入，按回车时会换行，但依然可以输入，这是怎么回事呢

[解决办法]
在scanf后面接着用getchar来接收回车键试试。
[解决办法]
scanf("%s %s %s %s",new->name,new->corp,new->phone,new->address);
==>
scanf("%s%s%s%s",new->name,new->corp,new->phone,new->address);

先像上面那样修改再说.

什么编辑器?怎么把行号一起复制过来了??

[解决办法]
改成这样了.
似乎是能够跳出去的..至于其他逻辑问题,你自己改吧.

PK，解决了。改了1个地方，把new改成了pnew。
