Build a graph with operators
############################
This section illustrates the use of C++ operators to simplify the
building of graphs.
Several C++ operators are overloaded to simplify graph construction.
For example, the following:
.. literalinclude:: ../../../examples/abc/abc.cpp
:language: cpp
:lines: 32-32
can be simplified to:
.. literalinclude:: ../../../examples/abc_operator/abc_operator.cpp
:language: cpp
:lines: 31
The expression ``a + b`` is equivalent to
``std::make_shared(a, b)`` and the ``*`` operator similarly
returns ``std::make_shared`` to its arguments.
