C++ program (using stacks) that reads from the user a mathematical expression like: (3+(4-9) * (3/4) * (3+2)) 1. The program should check if the expression is correct 1.1 An expression is correct if: the parantheses are correctly added and are balanced examples of not correct expressions can be: )9+8( (((8-1) etc Assuming that the numbers are only one digit 2. If the expression is correct, the program should evaluate the expression and display the result.
