Get the number of characters in a string

[brownhead]

class LongItem

	size_t length() = 0;

};


class StringCounter : LongItem

{

private:

	std::vector<LongItem *> characters;


public:

	StringCounter(char *zvalue)

	{

		char *c = zvalue;

		for (char *c = zvalue; *c != '\0'; ++c)

		{

			LongItem *newItem = new Character(*c);


			characters.push_back(newItem);

		}

	}


	size_t length() const

	{

		size_t num = 0;


		std::vector<LongItem *>::iterator i;

		for (i = characters.begin(); i < characters.end(); ++i)

			num += (*i)->length();


		return num;

	}


	~StringCounter()

	{

		std::vector<LongItem *>::iterator i;

		for (i = characters.begin(); i < characters.end(); ++i)

			delete *i;

	}

};


class Character : LongItem

{

private:

	std::string value_;

public:

	Character(char zvalue)

	{

		if (zvalue.length() != 1) throw std::invalid_argument("zvalue");

		

		value_(1, zvalue);

	}


	size_t length() const

	{

	}

};


int main()

{

	StringCounter counter("Hello world!");


	std::cout << "The length of the string is " << counter.length();


	return 0;

}
