#include<stdio.h>
int main(){
    double a,sn=0.0,k=1.0;
    scanf("%d",&a);
    if(sn<=a){
        sn=sn+1/k;
        k=k+1;
    }else{
        printf("%d",k);
    }

    return 0;
}

要循坏

@wuqikeqing 应使用 while 循环

@wuqikeqing

帮你改一下

#include<bits/stdc++.h>
using namespace std;
int main(){
    double a,sn=0;
    int k=0;
    scanf("%lf",&a);
    while (sn<=a){
        ++k;
        sn=sn+1.0/k;
    }
    printf("%d",k);
    return 0;
}
