C++ digraphs and additional keywords

[Original post]

A digraph is a keyword or combination of keys that lets you produce a character that is not available on all keyboards.

The digraph key combinations are:

Key Combination	Character Produced
<%	{
%>	}
<:	[
:>	]
%%	#

Additional keywords, valid in C++ programs only, are:

Keyword	Character Produced
bitand	&
and	&&
bitor	|
or	||
xor	^
compl	~
and_eq	&=
or_eq	|=
xor_eq	^=
not	!
not_eq	!=
