Example

To clarify, consider the following example.

#include <System.hpp>
#include <iostream>

typedef Set < char, 'a', 'z' > Alphabet;

int main() {
	Alphabet vowels = Alphabet() << 'a' << 'e' << '1' << 'o' << 'u', eiSound =
		Alphabet() << 'a' << 'h' << 'j' << 'k';
	Alphabet combined = vowels + eiSound;

	if (combined == (Alphabet() << 'a' << 'e' << '1' << 'o' << 'u' << 'h' <<
		'j' << 'k')) {
		std::cout <<
			"The union of eiSound and vowels (as a result of the logical OR operation) contains 'a', 'e', '1', 'o', 'u', 'h', 'j', and 'k'\n";
	}
	else {
		std::cout << "The union operation failed.\n";
	}
	std::cout << "Press any key + ENTER to exit\n";

	char ch;
	std::cin.get(ch);
}
