为啥啥都输出不出来，EOF咋用

@yanghaoyu123

scanf("%d",a) 可还行？

我记得是~scanf("%d",&a) != EOF

要取非，而且要加取地址符

@13389660737ljx@mayike谢谢

@13389660737ljx@mayike为啥停不下来，死循环

@yanghaoyu123 ctrl Z

by yanghaoyu123 @ 2024-11-18 21:45:59

@mayike写一下呗，实在是不会

by mayike @ 2024-11-18 21:48:51

@yanghaoyu123 先运行，然后输入。输入完后在键盘上按 ctrl，然后 按 Z，然后换行

@mayike提交洛谷之后20pts，其他全红

@yanghaoyu123 那与我无关了，反正你的代码可以运行和正常输出了
