Meng Xinqiu belt doesn't know why it's wrong
Attach code
#include<stdio.h>
int main()
{
float PI=3.14159;
float r,h,S,V;
printf("Please input r,h:");
scanf("%f,%f",&r,&h);
S=PIrr;
V=PIrr*h;
printf(" Bottom area =%f\t Cylinder volume =%f\n",S,V);
return 0;

}
Typed 5 and 6, The bottom area is correct, but the volume is always 0.
Please give me some advice
