C :

#include <stdio.h>
int main()
{
int i;
float m=0,n=0,sum=0;
scanf("%f %f",&m,&n);
for(i=1;i<=n;i++)
   {
   sum+=(m+m/2);
   m=m/2;
   }
    printf("%.2f %.2f\n",m,sum-m);
return 0;
}

C++ :

#include<stdio.h>
int main()
{
    float sum,m;
    int n;
    scanf("%f%d",&m,&n);
    sum=m;
    while(n--)
        {
            m=m/2;
            sum+=2*m;
        }
    printf("%.2f %.2f\n",m,sum-2*m);
}
