I’m working on a Programming question and need guidance to help me study.
Q1: Erroneous inputHere are two one-line inputs that give error messages if you type them into the interpreter: ^ ” Where are each of these errors generated? Why are they generated in different places?Q2: Valid inputSummarize what the tokenizer does when a user types the following at the interactive prompt:”Example string”Here’s the start: The interactive prompt is produced by Lox.runPrompt(), which calls Java’s built in readLine() to get a line of input. When the user enters that line as input, the interpreter calls Lox.run(“Example string”). Lox.run() then creates a new instance of the Scanner class, and calls scanTokens() on it.Starting from the call to scanTokens(), summarize what happens.Q3: Add a new operator(a) Add a new operator ^ for exponentiation, which tokenizes to POWER. This would let us write things like x = x^2; to square a number.Hint: This should work very similarly to +, -, /, and *, and requires changes in two files.For this question, include your actual code in the submission. That can be either a link to a repl.it, or screenshots/code in your submission document.(b) What if we wanted to use ** for exponentiation instead, like Python does? This would let us write x = x**2; instead. How would that change be different?You don’t have to actually implement this one, just answer in a sentence or two.
