hi,
i want to make an expression tree. but i don't know how. can any one provide me with an algorithm.
i need to store the boolean expression in the tree so that i can use it to draw the circuit diagram of the expression by traversing it in post order.i know the traversing part. i just need to know that how the expression tree is created. and one thing more, i m using C language therefore no STL.

please reply as soon as possible
Thanx a lot
