Evaluate Boolean expression given by the user by using tree data structure. An example of the Boolean expression is ((X1 * X2 * X3) + (X2 * X4) + (X5))
Where * and + is not static, i mean they can be any operator.

I think you missed to read the forum rules (http://www.codingforums.com/rules.htm)
1.5) No homework assignments  Do not post your entire homework assignment and request that other members do it for you. This is considered cheating, and your thread may even be used by your school to prove your guilt. Now, you may ask for advice or help on a specific aspect of your assignment that you're having trouble with. Use common sense as far as what's acceptable in terms of soliciting help with homework assignments.

 why do you need to mix characters and integers in same array?
 why do need a array?
you can use a union as item in array to store both type.
