Convert string to mathematical evaluation [closed]

Answer 1

I found what I was looking for! The downloadable source is C++ and a CodeBlocks project. You can find it here: http://www.speqmath.com/tutorials/expression_parser_cpp/index.html

A far more sophisticated expression parser recommended by Jared: http://www.partow.net/programming/exprtk/index.html

Answer 2

There is nothing built into C++ for this; all the expression parsing code belongs in the compiler. You will need to use some external library. A quick Google search brings up muParser which looks pretty reasonable.
