C++ 错误修复:夏威夷语发音程序

我正在编写一个C++程序，它将向您展示如何发音夏威夷语单词。

规则：

• p， k， h， l， m， n (发音与英文版本相同。
w
• -单词的开头(发音为 w 或 v 音。 我们将它发音为w音。
w
• - 在字母"a"之后(发音为 w 或 v 音。 我们将它发音为w音。
• w - 在"i"或"e"之后(发音为v音。
w
• - 在"u"或"o"之后(发音为w音。

我的进度：我的程序可以工作，但有几个错误。

1. 当我输入"iwa"时，发音必须是"ee-vah"，但我是 得到"哎呀

   "。

2. 我的代码没有忽略空格。因此，当我输入"e komo mai"时，我想要"eh koh-moh meye"，但相反，我得到"e komo mai发音为eh-eh-koh-moh-oh-meye"。

这是我的代码：

#include <iostream>
#include <string>
#include <algorithm>
#include <vector>

// Declare my variables
string userInput;
string replacement;
//cout << "Enter a hawaiian word to pronounce ==>";
getline(cin,userInput);
// For loop that will call my Consonant function
// Call my Hawaiian function and put it
// into pronunciation 
replacement = convertToHawaiian(userInput);
// if My initial input has a capital, the replacement
// will keep the capital letter at the beginning
if (isupper(userInput.at(0))) {
replacement.at(0) = toupper(replacement.at(0));
}
// Get rid of the '-' character at the end of the string
if (replacement.at(replacement.size() - 1) == '-') {
replacement.pop_back();
}
