Question
The focus of this assignment is to create a class that displays ASCII an image stored in a 2D array on a screen at the user-defined location. The class should have the capability of displaying and erasing the image. This assignment will also require you to create two other files besides your main.cpp.
- Create three files.
- main.cpp - Client code
- image.cpp - Class implementation file
- image.h - Class declaration/interface file
- In the main.cpp, create a 2D (any size between 5x5 and 12x12) array with the image you like
- Create an object of the class Image and initialize it using 2D array
- Move the object around the screen (pick your pattern). At least four different directions should be used
- Incorporate the color change in your program.
The complexity of your program is up to you.
At a minimum:
- Your class should have at least one private member variable and at least one public member function, and a constructor.
- The image should move on the screen at a reasonable speed for humans to see.
- At least four directions and four colors should be demonstrated.

It should store filename as its attribute (with a accessor getFilename(). The class should have the following methods: • createUpperCaseFile(): Accepts a String parameter targetFilename. It will open up both the file specified in class attribute filename and the method parameter targetFilename. Then it will convert all lines of the class attribute filename to upper case and write it to target file, line by line. • createRowCharCountFile(): Accepts a String parameter targetFilename. It will open up both the file specified in class attribute filename and the method parameter targetFilename. Then it will count the number of chars in each line of the class attribute filename and write it to target file line by line. The class must come with a main() method, which will create an object instance and generate two target files based on the source file, one all upper case, and another row char count.arrow_forward

The first user input will be a single word the second user input will be a sentence of random words. This program should print "true" if the first word is in the sentence of words regardless of the casing. In other words case is ignored when checking if the word is within the sentence.

- Write a class name FileDisplay with the following methods: Constructor: takes the name of a file as an argument displayHead: displays only the first five lines of the file’s contents. If the file contains less than 5 lines, it should display the file’s entire contents. displayContents: displays the entire contents of the file, the name of which was passed to the constructor. writeNew: displays the contents of a file, the name of which was passed to the constructor. Each line should be preceded with a line number followed by a colon. The line numbering should start at 1. As each line is displayed it should also be written to a new file, the name of which is passed in as a parameter. I have provided a test file called “testfile.txt”. I have also provided a driver for the application called “filedisplaytest.java”. This file is complete and should not be altered. Test File: This is line one.This is line two.This is line three.This is line four.This is line five.This is line…arrow_forwardcreateDatabaseOfProfiles(String filename) This method creates and populates the database array with the profiles from the input file (profile.txt) filename parameter. Each profile includes a persons' name and two DNA sequences. 1. Reads the number of profiles from the input file AND create the database array to hold that number profiles. 2. Reads the profiles from the input file. 3. For each person in the file 1. creates a Profile object with the information from file (see input file format below). 2. insert the newly created profile into the next position in the database array (instance variable).arrow_forwardWritten in Python with docstring please if applicable Thank youarrow_forward
- In C++ Please: The class and functions need to be on an .h file while the main needs to be small and on a seperate .cpp file. Create a class AccessPoint with the following attributes: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Also, add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overlap that checks if two access points overlap their coverage and returns true if they overlap. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location.

This program uses a Student class that is provided and shown below. The class is placed in its own separate file and should not be altered. This program sequence started with Lab06a. It is a reminder that it is the same Student file used by Lab06a. This lab will add data processing to the earlier Lab06a. This program will continue with the Lab06b program that performs some data processing on the Student records. For this lab 10 Student objects need to be constructed and placed in a students array, which is stored in a School object. You actually did this already for Lab06a. You also need to complete the School constructor, addData method and toString Method, which were in Lab06a. Feel free to just copy them over. You need to complete three bubbleSort methods; one that sorts according to the student gpa., one for age and one for name.…arrow_forward
