用C写的压大小的小程序

#include "stdio.h"
#include "stdlib.h"
#include "time.h"

void guess();

main()
{
 printf("You have 10$./n");
 guess();
}

void guess()
{
 int num=0,temp=0;
 int m=10;
 char c;
 do
 {
  srand(time(NULL));
  num=rand();
  num=num%2+1;
  printf("please press B or S:");
  c=getche();
  c=='b'?temp=1:(c=='s'?temp=2:exit(1));
  if((temp==num)&&(temp==1)) m+=8;
  if((temp==num)&&(temp==2)) m+=4;
  if(temp!=num) m-=5;
  printf("You have %d$/n",m);
 }while((temp==1)||(temp==2));
}
