或者直接输出的时候减一也可以

    cin>>k;
    while(s<k)
    {

        s+=1.0/n;
    }
    scanf("%d",&n);
} 

@Adhara 这样？

wtf您别瞎用scanf啊。。。

by Adhara @ 2020-05-17 14:06:03

@zengxiangtuo scanf("%d",&n);改成printf("%d\n",n);

@江户川·萝卜 好的呢

by 江户川·萝卜 @ 2020-05-17 14:06:23

直接cout<<n它不香吗

by imbecile @ 2020-05-17 14:06:47

@江户川·萝卜 md记错了
