C :

#include <stdio.h>
int main()
{
	int h,i;
	double h0,s=0; 
	scanf("%d",&h);
	h0=(double)h;
	for(i=0;i<10;i++){
		if(i==0){
			s+=h0;
		} else{
			s+=h0*2;
		}
		h0/=2;
	}
	printf("%g\n%g",s,h0);
	return 0;
}

C++ :

#include<iostream>
using namespace std;
int main(){
	double s1=0,n;
	cin>>n;
	for(int i=1;i<=10;i++){
		s1+=n;
		n/=2.0;
		s1+=n;
	}
	s1-=n;
	cout<<s1<<endl;
	cout<<n<<endl;
}
