Course Project 2: Design A Simple Calculator Problem: Design the DFA machine for a simple calculator, where s-{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, (DO[.)) "U" is used for only one operation each time (e g. 3.D42248) embedded [!.11 is not allowed of (1) Design a regular expression r for real number expression. A real number can be negative or positive (e g, -2.5 and 0.52) A real number expression is an expression of real numbers connected by four arithmetic operations t,, x,, /and priority D convert it to & DIA Design a regular grammar to generate the regular language Lr). Implement the DIA using C# orJava (ie., accept the strings in language L(f)). The mput is a (2) Design a DFA for accepting the regular language Lin), You can first design a NFA and then (3) (4) string and output is "accepted" or "rejected" The prejeet report must contain the fellowing components: .User instructions Stepwise instructions that tell the customers s how to use the calculator - Detailed explanation for (1), (2), (3) board, Cutput accept or reject Team work (workioad of each team member and coliaboration in the team)
