How to ignore punctuation in piglatin program (edited)

[james42]

I figure out how to get it to change the sentence into piglatin, but after hours of searching on how to ignore punctuation, I am still confused on how to do this. I want the punctuation to be at the end of any word that has any punctuation. How should I do this?


Given the following:

struct Word
{
	string english;
	string piglatin;
};


Word * piglatinCon(Word sentenceArr [], int &wordNum)
{
	string s, c;
	int i = 0;
	Word *str = nullptr;
	str = new Word[wordNum];

	for (int count = 0; count < wordNum; count++)
	{
		if (*sentenceArr[count].english.begin() != 'e'  &&            *sentenceArr[count].english.begin() != 'i' && *sentenceArr[count].english.begin() != 'o' && *sentenceArr[count].english.begin() != 'u' && *sentenceArr[count].english.begin() != 'a' && *sentenceArr[count].english.begin() != 'E' &&   *sentenceArr[count].english.begin() != 'I' && *sentenceArr[count].english.begin() != 'O' && *sentenceArr[count].english.begin() != 'A' && *sentenceArr[count].english.begin() != 'U')
		{
			// Converts to pig latin
			c = *sentenceArr[count].english.begin();
			s = sentenceArr[count].english.erase(0, 1);
			str[i].piglatin = s + c + "ay";
		}

		// Any other letter it will just add way to the end of the word
		else
			str[i].piglatin = sentenceArr[count].english + "way";
		i++;
	}

	return str;
}

Thanks for your help, I was able to remove the punctuation and then do the piglatin conversion. So now I want to add the punctuation after the conversion, so is there any way to do this?

My implementation of the Code:

 else
		{
			 temp[i].english += sentence[count];
			 regex re("[[:punct:]]");
			 temp[i].english  = regex_replace( temp[i].english, re, "");
		 }

So now I want to add the punctuation after the conversion

add the punctuation back to what, temp[i].english? In which case it'd be the temp[i].english before the regex_replace

[james42]

So I would add the puncuation back to the piglatin field after the conversion.

why not just save a copy of the original string with the punctuation and use another copy to remove punct?
