Calculator Program in C++

Hi, I am attaching a simple working calcuator program in CPP. It needs to be expanded so it can use a SymbolTable which is used in [login to view URL] and also the claculator need to do few more functionality than what it supports now. The program should be able to run in UNIX environment. To your calculator program, I want you to add a read-only symbol table that is pre-populated with initial values. For example, you might wish to have your table know about some constants: Fact3 = 6; Dozen = 12; Mil = 1000000; Bil = 1000000000. But i need a solution within 2 days. I hope you can make it. Please let me know. Thanks. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Expand the calculator with few additional features like a real calcualator. Atleast 5 diferent additional functions. ## Platform Unix Environment
