高空坠球：皮球从height（米）高度自由落下，触地后反弹到

[问答题]

高空坠球：皮球从height（米）高度自由落下，触地后反弹到原高度的一半，再落下，再反弹，……，如此反复。问皮球在第n次落地时，在空中一共经过多少距离？第n次反弹的高度是多少？输出保留一位小数。试编写相应程序。

#include <stdio.h>
int main(void)
{
    int i, n;
    int repeat, ri;
    double distance, height;
    scanf("%d", &repeat);
    for(ri = 1; ri <= repeat; ri++){
        scanf("%lf%d", &height, &n);
 distance = height;
 while(n > 0){
   height = height / 2;
   distance = distance + height * 2;
   n--;
 }
 distance = distance - height * 2;
       printf("distance = %.1f, height = %.1f\n", distance, height);
   }
}

#include<stdio.h>
int main(void)
{double height,lenght=0,h;
int n,i;
printf("输入初始高度=");
scanf("%lf",&height);
printf("输入弹跳次数");
scanf("%d",&n);
h=height;
for(i=1;i<=n;i++)
{h=h*0.5;
lenght=lenght+3*h;
}
printf("h=%.1lf lenght=%.1lf",h,lenght);
return 0;
}

/*
高空坠球

总共经过了多少距离，使用等比数列求和公式
第几次弹多高，类似于利润的年增长率，小学思想  基数*（1+增长率）^n
