Program dosnt end

I have no idea to why the following code never ends

P.S: Ascender are letters that pass the second line in a writing copy, like 'f', 'k'. and descenders are the opposite, they cross the bottom line, ex 'g', 'y'.

  int main()
{
	const string ascenders = "tdfhklb", decenders = "qypgj";
	ifstream file("input.txt");
	string input, mostAscDec;

	while (file >> input) {
		unsigned count = 0, lrgstCount;
		string::size_type pos = 0;

		while (input.find_first_not_of(ascenders, pos) != string::npos && input.find_first_not_of(decenders, pos) != string::npos) {
			++count;
			if (count >= lrgstCount) {
				lrgstCount = count;
				mostAscDec = input;
			}
		}
	}
	cout << "Word with the least ascenders and decenders: " << mostAscDec << endl;
	return 0;
}

Line 11. If finds something, then you are doing something and then it searches same string for same letters. No wonders it finds something again.

Waw what a stupid mistake. There were a few other mistakes to so fixed em up. Here is the updated code

int main()
{
	const string ascenders = "tdfhklbTDFHKLB", decenders = "qypgjQYPGJ";
	ifstream file("input.txt");
	string input, mostAscDec;
	unsigned lrgstCount = 0;

	while (file >> input) {
		unsigned count = 0;
		string::size_type pos = 0;

		while (input.find_first_of("weruioaszxcvnm", pos) != string::npos) {
			++count;
			if (count >= lrgstCount) {
				lrgstCount = count;
				mostAscDec = input;
			}
			++pos;
		}
	}
	cout << "Word with the least ascenders and decenders("<< lrgstCount << "): " << mostAscDec << endl;
	return 0;
}
