ac代码

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n;
    cin>>n;
    double s=1;
    for(int i=2;;i++){
        s+=1.0/i;
        if(s>n){
            cout<<i;
            break;
        }
    }
    return 0;
}

用你代码改的

#include<bits/stdc++.h>
using namespace std;
int main(){
    int k=0;
    double n;
    double sn=1.0;
    cin>>k;
    for(n=2;;n++){
        sn+=1.0/n;
        if(sn>k){
            break;
        }
    }
    cout<<n;
    return 0;
}

1.float改成double
2.应该改成1.0/n(或者把n改成double)
3.条件单独判断
