#include<iostream>
#include<cstdio>
#include<cstdlib>
#include<cmath>              //我把知道的都写上了
using namespace std;
int main()
{
   double n,k,i,sum=0;
    scanf("%d",&k);
    for(double n=1;;n++)
    {i=1/n;
     sum+=i;
     if(sum>k)
     {printf("%d",n);
      system("pause");
      return 0;
    }
    }
}

@涵塘听雨 你确定double的变量能用%d输出？system要去掉

这是我写的

#include <iostream>
using namespace std;
int main(){
    long k,i;
    cin >> k;
    double s=0.0;
    for (i=1;s<=k;i++)
    s=s+1.0/i;
    cout << i-1;
    return 0;
}
