怎么会呢?我用你的代码把long double改成double 就AC了呀

还有为什么你的include<cstdio>没有‘#’号@建建、

这不是你的代码吗?我就把long double改了一下呀!@[建建丶](/space/show?uid=156495)
```cpp
#include<iostream>
#include<cstdio>
using namespace std;
int main() {
int i;
double x,d=0,s=2;
scanf("%lf",&x);
while(d<x) {
d+=s;
i++;
s*=0.98;
}
printf("%d",i);
return 0;
}
```
