本题要求实现一个常用圆形体体积的计算器。计算公式如下：
在每次计算之前，要求输出如下界面：
1-Ball
2-Cylinder
3-Cone
other-Exit
Please enter your command:
然后从标准输入读进一个整数指令。
如果读入的指令是1或2或3，则执行相应的体积计算；如果是其他整数，则程序结束运行。
Please enter the radius:，然后读入球体半径，完成计算；Please enter the radius and the height:，然后读入底圆半径和高，完成计算；Please enter the radius and the height:，然后读入底圆半径和高，完成计算。计算结果在一行内输出，保留小数点后两位。

1-Ball 2-Cylinder 3-Cone other-Exit Please enter your command: Please enter the radius: 33.51 1-Ball 2-Cylinder 3-Cone other-Exit Please enter your command: Please enter the radius and the height: 18.10 1-Ball 2-Cylinder 3-Cone other-Exit Please enter your command:
代码：
#include <stdio.h> #include <string.h> #include <math.h> #define PI acos(-1) int main() { int d,flag = 0; double r,h; printf("1-Ball\n2-Cylinder\n3-Cone\nother-Exit\nPlease enter your command:\n"); while(scanf("%d",&d)) { switch(d) { case 1: printf("Please enter the radius:\n"); scanf("%lf",&r); printf("%.2f\n",PI * 4 / 3 * r * r * r); break; case 2: printf("Please enter the radius and the height:\n"); scanf("%lf%lf",&r,&h); printf("%.2f\n",PI * r * r * h); break; case 3: printf("Please enter the radius and the height:\n"); scanf("%lf%lf",&r,&h); printf("%.2f\n",PI * r * r * h / 3); break; default: flag = 1; } if(flag) break; printf("1-Ball\n2-Cylinder\n3-Cone\nother-Exit\nPlease enter your command:\n"); } }
