一个求圆柱体体积的C语言小程序，求改错。

C/C++ code

#include<stdio.h>void main(){int h;float pi,r,c,s1,s2,v1,v2;pi=3.1415926;printf("请输入圆半径r和圆柱高h:\n");scanf("r=%f\nh=%d\n",&r,&h);c=2*pi*r;s1=pi*r*r;s2=4*pi*r*r;v1=4*pi*r*r*r/3;v2=s1*h;printf("圆周长=     c=%6.2f\n",c);printf("圆面积=     s1=%6.2f\n",s1);printf("圆表面积=    s2=%6.2f\n",s2);printf("圆球体积=     v1=%6.2f\n",v1);printf("圆柱体积=     v2=%6.2f\n",v2);}

C/C++ code

scanf("%f,%d",&r,&h);
