creating logic gates simulator

[Buzz1982]

hi,
i m working on a project and want some opinions on how to implement certain things ,the description is below,

i m making a logic gates simulator.if u give it some equation it should generate truth table and diagram.
if u give diagram then produce its equation and truth table.

implementation of truth table part:
i am converting string equation in to postfix form then solving it to get the final result(all right till here)

implementation of generating diagram from equation?????????
i m confused please help.just give me a general idea ill be thankful

What diagram? I don't understand.

Truth table only contains True or false(1s & 0s). Should be quite simple IMO.

Try doing some equations yourself first to familiarise, afterall in the end, you can use the worked equations to test your program.

The problem I think you would have, is the parsing the equation to meaningful input for your program to work on.

i have done the parsing and had got the result
but the problem is that i also have to draw the diagram according to the equation eg
a+(b.c)

so the diagram would look like this

first b and c will enter the AND gate and then the output from AND gate & a will enter the OR gate
