@[HardBlackPencil](/user/1080089) 你`cin>>s;`之后又去`f=getchar()`干什么？？？

把`cin>>s;`删了
by Genshineer @ 2023-09-03 13:27:38
再把`number = number * 10 + (int)f;`改成`number = number * 10 + (int)f-48;`

啊对对对

@long_long_integer谢谢，而cin>>s是个历史遗留问题
by HardBlackPencil @ 2023-09-03 14:08:19
@[long_long_integer](/user/191248) (int)(f-48)吧？
