You are in the following subdirectory
** `interpret++`
This code take mathematical expressions and evaluates them,
i.e. it outputs numbers. It is the same as its sister folder `interpreter`
as far as recursive descent parsing goes, but uses more C++ features and
is set up so as to support growing up to be a larger project.
** `halfBakedCompiler`
This code take mathematical expressions and builds an abstract syntax tree,
a.k.a. an AST. It then dumps this AST as text.
The parsing is equivalent to that in `interpreter` and `interpret++`
(neighboring directories and predecessor programs).
This version builds on `interpreter++` (and also requires C++17).

To test the program, run `make tests`. This also illustrates how the intepreter is used.
Alternatively, just run the program with *no* parameters (i.e. simply `./intepret++`).
