  //我自己又写了一个给你们参考
  #include <stdio.h>

  int main()

  {

  int scor=2008;
  int q=8;
  int w=8;
  int a,s,d,f;
  a=0;
  if(scor%4==0)
  {
  d=29;
  f=366;
  }
  else
  {
  d=28;
  f=365;
  }
  switch(q)
  {
  case 1: a+=31;
  case 2: a+=d;
  case 3: a+=31;
  case 4: a+=30;
  case 5: a+=31;
  case 6: a+=30;
  case 7: a+=31;
  case 8: a+=31;
  case 9: a+=30;
  case 10: a+=31;
  case 11: a+=30;
  case 12: a+=31;
  }
  s=f-a+w;
  printf("%d\n",s);
  return 0;
