问题解决
while(Current->next!=NULL&&strcmp(newstr,oldstr)>0)
{
memset(oldstr,0,sizeof(oldstr));
sprintf(oldstr,"%s\t%s\t%s\t%s\t%s",Current->substr,Current->sfztjm,Current->zdztjm,Current->ch,Current->xx);
Prior=Current;
Current=Current->next;
  } 中memset(oldstr,0,sizeof(oldstr));
sprintf(oldstr,"%s\t%s\t%s\t%s\t%s",Current->substr,Current->sfztjm,Current->zdztjm,Current->ch,Current->xx);位置不对
正确的应为
while(Current->next!=NULL&&strcmp(newstr,oldstr)>0)
{
Prior=Current;
Current=Current->next;
memset(oldstr,0,sizeof(oldstr));
sprintf(oldstr,"%s\t%s\t%s\t%s\t%s",Current->substr,Current->sfztjm,Current->zdztjm,Current->ch,Current->xx);  } 看来这里人气不佳啊…………
