有两个错误。麻烦高手们·请告诉小弟 哪儿错了。。。原因。。。以及解决方法·

#include <stdio.h>
#define inch_cm 2.54
double I_C(double inch)
{
double cm;
cm=inch*inch_cm;
return cm;
}
printf_star_inch()
{
           printf("*****************************************\n");
           printf("*                                       *\n");
         printf("*   please input ______ inch            *\n");
           printf("*                                       *\n");
          printf("*****************************************\n");
          }
printf_end_inch(double inch,double cm)
{
           printf("*****************************************\n");
           printf("*          %.2lf inch = %.2lf cm        *\n",inch,cm  );
           printf("*****************************************\n");
           }
main()
{
double inch,cm;
clrscr();
      printf_star_inch();
    scanf("%lf",&inch);
    cm=I_C(inch);
    clrscr();
      printf_end_inch(inch,cm);
}
少两个}号，并且函数printf_end_inch未传递参数
