Description: It is also based on the arithmetic expression evaluation on the issue, not the same as the previous question, in the hope useful to those in need. Solving the expression problem
Design a program to achieve that arithmetic expressions based on binary tree operations.
1, needs analysis
1. Arithmetic expression valid input data, including the variable (A ~ Z, a ~ z), constant (0-9) and the binary operators (+,-,*,/,^( exponentiation)). Procedures for data input format is not required, the user must ensure that their grammar is correct, see the user manual instructions.
2. Demo program to man-machine dialogue manner, that is, the computer displays a prompt message, by the user on the keyboard corresponding to the input data or command, the program will execute the corresponding action and displays the next message.
3. Program execution commands include:
1) According to user input automatically add the prefix of an expression in parentheses and the establishment of its natural e
