OCaml Code: The goal of this project is to understand and build an interpreter for a small, OCaml-like, stackbased bytecode language. Make sure that the code compiles correctly and provide the code with the screenshot of the output. The code must have a function that takes a pair of strings (tuple) and returns a unit. You must avoid this error that is attached as an image. Make sure to have the following methods below:
-Push integers, strings, and names on the stack
-Push booleans
-Pushing an error literal or unit literal will push :error: or :unit:onto the stack, respectively
-Command pop removes the top value from the stack
-The command add refers to integer addition. Since this is a binary operator, it consumes the toptwo values in the stack, calculates the sum and pushes the result back to the stack
- Command sub refers to integer subtraction
-Command mul refers to integer multiplication
-Command div refers to integer division
-Command rem refers to the remainder of integer…

- Your understanding of importing modules, using lists and dictionaries and creating objects from a class will be exercised in this lab. Be prepared to use your solution for the “Classes” lab (see Blackboard for the link) where you wrote the PlayingCard class. In this lab, you will have to generate a random list of PlayingCard objects for where the suit and rank combinations of each card are randomly choosen. Using this list of randomly created playing cards, you will use dictionaries and lists to store important data about these playing cards, particularly the frequency distribution of each rank-suit combination you created (e.g. like if 10 queen of hearts cards are generated and counted.) Thanks to the clearly described interface used to communicate to any PlayingCard object, specifically the get_rank() and get_suit() methods, you can just import your “Classes” lab as a module and use your previously written code! Note: You’ll definitely need to make sure your solutions work for this…arrow_forwardTo demonstrate working with ArrayLists, we will be working with four source files: a Dessert class, two classes that extend Dessert called IceCream and Cake, and a TestDessert class. The TestDessert class contains a main() method that declares an ArrayList to hold Dessert objects. This ArrayList is referenced by the variable named "list". Examine TestDessert's main() method and notice the four comments. You are to implement code that accomplishes the tasks described in each step. For step 1, you are to populate the ArrayList with 10 IceCream and Cake objects. These objects should be inserted into the ArrayList at random. This means each run of the program should produce an ArrayList with different proportions of IceCream and Cake objects. After this operation, the ArrayList should contain 10 total objects (IceCream and Cake objects). Display the ArrayList after the operation. For step 2, if the first and last dessert in the ArrayList are different (one is IceCream and the other is…arrow_forwardThe function remove of the class arrayList removes only the first occurrence of an element.

- //Need help fixing some issues with a project. PLEASE read below Write a Java program that implements both Linear Search and Binary Search. The program will take a collection of objects (generic type data) as input and print the number of comparisons needed to find a target element within that collection. You will create the following two Java classes:1. SearchCombo.java : Code for both linearSearch and binarySearch will be in this class. You may take help from the textbook Chapter 9, Section 9.1. However, note that the design requirements are different from the textbook code.•Both search methods must use the Comparable<T> interface and the compareTo() method.•Your program must be able to handle different data types, i.e., use generics.•For binarySearch, if you decide to use a midpoint computation formula that is different from the textbook, explain that formula briefly as a comment within your code. 2.

Sometimes, the parking attendant will add special notation to help her remember something about a specific entry. There are just non alphabetic characters that she adds to the state - your program should ignore these characters so that an entry like NY* still counts toward the NY plate count. She is also very inconsistent with how she enters the plates. Sometimes she uses upper case, sometimes lowercase, and sometimes she even uses a mix. Be sure to account for this in your program. Only add information for plates in New England (Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut).

- A programmer is designing a program to catalog all books in a library. He plans to have a Book class that stores features of each book: author, title, isOnShelf, and so on, with operations like getAuthor, getTitle, getShelf Info, and set Shelf Info. Another class, LibraryList, will store an array of Book objects. The LibraryList class will include operations such as listAll Books, addBook, removeBook, and searchForBook. The programmer plans to implement and test the Book class first, before implementing the LibraryList class. The program- mer's plan to write the Book class first is an example of (A) top-down development. (B) bottom-up development. (C) procedural abstraction. (D) information hiding. (E) a driver program.arrow_forwardIn C++, Write the implementation for the methods of the Node class including the constructor. The constructor should set value to the passed in parameter, and set the value of the next pointer to NULL. getNext() should return the value of the next pointer. setNext() should set the value of the next pointer to the parameter that is passed in. In the main() function below (where it says // Step 2 code here), write the code to make a list of 10 Node objects. To do this, make a root pointer which is a pointer to a Node object, and then use a loop to create new Nodes, hooking up the list using setNext() and getNext() for each node. Set the value of each new Node to be the even numbers 2 through 18 (in addition to the root node which has value 0). Make sure that your nodes are linked together!

- EclipseIDE - Java Programming assigment For your program: Create a data class named Automobile that implements the Comparable interface. Give the class data fields for make, model, year, and price. Then add a constructor, all getters, a toString method that shows all attribute values, and implement Comparable by using the year as the criterion for comparing instances. Write a program named TestAutos that creates an ArrayList of five or six Automobiles. Use a for loop to display the elements in the ArrayList. Sort the Arraylist of autos by year with Collections.sort(). Finally, use a foreach loop to display the ArrayList sorted by year.arrow_forwardThis is for python For this assignment, you will write a program to simulate a payroll application. To that effect, you will also create an Employee class, according to the specifications below. Since an Employee list might be large, and individual Employee objects may contain significant information themselves, we store the Employee list as a linked list. Employee class: Attributes • Employee ID: you can use a string – the ID will contain digits and/or hyphens. The ID must be provided during object construction and there should be no mechanism to change it later. • Number of hours worked in a week: a floating-point number. • Hourly pay rate: a floating-point number that represents how much the employee is paid for one hour of work. • Gross wages: a floating-point number that stores the number of hours times the hourly rate.

Create a List called phoneNumbers and use the add method to add several phone numbers to the list. List<String> phoneNumbers = new ArrayList<>(); phoneNumbers.add("555-555-1234"); phoneNumbers.add("555-555-2345"); phoneNumbers.add("555-555-3456"); phoneNumbers.add("444-444-1234"); phoneNumbers.add("333-333-1234"); Create a Set called prefixes and use a for-each loop to iterate over the phoneNumbers list. For each phone number, we use the substring method to extract the first 7 characters, which represent the prefix, and add it to the prefixes set using the add method.
