```c
#include<stdio.h>
int main()
{
int n=0,x=2,flag=1;
double s,m=2;
scanf("%lf",&s);
if(x<=2)
{
printf("%d",flag);
}
else{
while(m<s)
{
x=x*0.98;
m=m+x;
n=n+1;
}
}
printf("%d",flag);
return 0;
} //他的代码

```#include<iostream>
using namespace std;
int main(void)
{
double h,a;
cin>>h;
for(double i=2.0;h>0;i*=0.98)
{
h-=i;
a++;
}
cout<<a;
return 0;
}```
