不知道该为函数的最后一个代码字符串写什么

嗨，伙计们，这是我迄今为止对函数的了解，问题是让我写一个函数findpattern()，它将接收代表三个保龄球得分的三个整数。该功能将确定这些分数所遵循的模式，打印以下六种情况之一（确保您有这六种情况）：

  stayed the same –- all three scores were the same 
  increasing –- the scores are going steadily upward
  decreasing –- the scores are going steadily downward
  up and down –- the scores first went up, then went down
  down and up –- the scores first went down, then went up
  two the same –- two consecutive scores were the same, and the
 other one (first or third) was either higher or lower     

这就是我到目前为止所拥有的，我不知道最后一部分，任何帮助都将不胜感激

void findpattern(int score1, int score2, int score3)
{
   if (score1 == score2 && score1 == score3 && score2 == score3 )
   {
      cout << "all three scores were the same" << endl;
   } else if (score1 < score2 && score2 < score3) {
      cout << "the scores are going steadily upward" << endl;
   } else if (score1 > score2 && score2 > score3) {
      cout<<"the scores are going steadily downward"<<endl;
   } else if(score1 < score2 && score2 > score3) {
      cout << "the scores first went up, then went down" << endl;
   } else if (score1 > score2 && score2 < score3) {
      cout<<"the scores first went down, then went up"<<endl;
   }
