Two types of persons need to make рayment: - Class LoanLender describes a loan. For a loan, we have a maximum limit for example 100K, and an interest rate, for example 7% - Class SIMUOW describes a student who needs to pay school fees depending on the number of areas of focus. Students can take at most two areas of focus. For example, per area of focus cost is 5K per term, and project's cost is 10K.

Much like the Lexer, it has a constructor that accepts a LinkedList of Token and creates a TokenManager that is a private member. The next thing that we will build is a helper method – boolean AcceptSeperators(). One thing that is always tricky in parsing languages is that people can put empty lines anywhere they want in their code. Since the parser expects specific tokens in specific places, it happens frequently that we want to say, “there HAS to be a “;” or a new line, but there can be more than one”. That’s what this function does – it accepts any number of separators (newline or semi-colon) and returns true if it finds at least one. Create a Parse method that returns a ProgramNode. While there are more tokens in the TokenManager, it should loop calling two other methods – ParseFunction() and ParseAction(). If neither one is true, it should throw an exception. bool ParseFunction(ProgramNode) bool ParseAction(ProgramNode) -Creates ProgramNode,…arrow_forwardWhat Is The Difference Between A Copy Constructor And An Overloaded Assignment Operator?arrow_forward
