Character variable holds a single character. It is used to process
text.

	char a, b, c, d, e;
	a = 'H';
	b = 'e';
	c = 'l';
	d = 'l';
	e = 'o;;
	cout << a << b << c << d << e;

outputs
	Hello

Here is another example:

       char charInput;
       cin >> charInput;
       if(charInput == 'x')
           cout << "You input letter x" << endl;

Unlike string constants, that can contain multiple characters, a
character variable or constant can contain only a single character.
