I used the expression parser of graphit! example program in vb-helper.com but it is still limited and it produce an error message when it encounters nested parenthesises with an operator after it like:
sin(x+1)+1
| |
--|-
this causes the error.
How do you make an expression parser that can go about this error?
Click here for the source code goto school activities and run IDE Grapher.exe
need your help.
A Web search or a good library should provide all sorts of literature on parsing algebraic notation. Does a nearby college have computer sciience courses? If so, they should be able to recommend a source for this.
Most of the algorithms translate to Reverse Polish notation, which is easy to use as the basis for machine language code or a VB program.
The algorithms should not be difficult ot implement in almost any language.
