string function find.

[chewykb24]

Hi im making this hangman game, and i got the word they enter as a string and the letter they want to guess as a string, so i was wondering when i use the find function and say i have a word like jelly or something with double letters, what would find return? or how would i use find with the other erase and insert functions if there was double letters? thanks for any help.

As for dealing with n3wbs that want to use multiple letters, you may check to see if the given string size is greater than 1 using strlen or <string>.size();. Honestly, it shouldn't matter. When you check for the string, if the entire string isn't in the word, then it fails to find it. Say we have needle. If I use find to search for ned, it will find one occurance but no others meaning the other e is still hidden like a regular game. If you search for e, it will find the first one, then you have to call it again until npos flag is given. Have fun. :D

ok thanks man, i think thats just what i need. Im a little confused in the example it uses though and how it find the second needle, in

found=str.find("needles are small",found+1,6);

i dont get what the is the deal inside those brackets? thanks for any help once again.

int guess(string realword, int wordlength, int attempts, string solution)
{
	int temp;
	int count;
	int variable;
	string letter;
	string newsolution;

	variable = attempts;

	count = 1;
	while (count <= attempts)
	{
		cout << "Guess a letter (you have " << variable-- << " left): ";
		cin >> letter;
		
		temp = realword.find(letter);

		if (temp < 0 || temp > attempts)
		{
			cout << "Wrong, try again. Word so far is " << solution << endl;
		}
		else
		{
			solution.erase(temp, 1);
			solution.insert(temp, letter);

			newsolution = solution;

			cout << "Right! Word so far is " << newsolution << endl;
		}
			if (solution == realword || newsolution == realword)
			{
				cout << "Good job, you win!" << endl;
				return 1;
			}

		count++;	
	}

	cout << "Computer wins, you lose!" << endl;
	return 1;
}
