include<stdio.h>

int main() { int a,b,sum,i; sum=0; scanf("%d",&a); for(i=1; sum<a; i++) { sum=sum+1/i; }

printf("%d",i);

@胡子骁 使用浮点型即可AC.

#include<stdio.h> 
int main()
{
    int a,i; 
    float b,sum; 
    sum=0.0; 
    scanf("%d",&a);
    for(i=1; sum<a; i++)
    {
        sum=sum+1.0/i;
    }
    printf("%d",i);
    return 0;
}
