Need help not loading a String if it contains an apostrophe

[Wolf CCMLG]

Hi,

I am loading in a dictionary text file of English words, but I am not supposed to load any words if they contain an apostrophe. I am loading them in as strings, and I cannot figure out how not to load the string if it contains an apostrophe. Here is my code. Thanks.

class Dictionary
{
private:
	ifstream in;
	string word;
	int numOfWords;
 
public:
	Dictionary();
	~Dictionary(void);
	void Load(const char* filename);
};

void Dictionary::Load(const char* filename)
{
	numOfWords = 0;

	in.open(filename);
	if (!in.is_open())
	{
		cout << "ERROR! Cannot locate file: " << filename << '\n';
		return;
	}
	HTable<string> hTable(NUMOFBUCKETS,Hash);
	while(true)
	{
		getline(in, word, '\n');
		if(in.eof())
			break;

		// All words read in must be 3 to 6 characters long
		if(word.length() > 2 && word.length() < 7)
		{
				hTable.insert(word);
				++numOfWords;
		}
	}
	cout << "Number of words loaded into dictionary Hash table: " << numOfWords << endl;
}

You could use .find() - see the examples at http://www.cplusplus.com/reference/string/string/find/ (there's an overload for a character to be matched)

You already check to see if the word has 3-6 characters. Also check for an ' too before inserting the word.

Thanks guys! ^_^

Oops, had a small mistake.
