Create a Matrix class and implement the following member functions: in C++, A= The constructors and the destructor • getSize() which returns the size of the matrix; ● setValue(int position, int value) which sets the value in the matrix at given position; getValue (int position) which returns the current value at given position; an add method which adds two matrices together; a subtract method which subtract two matrices together; ● ● ● a multiply methods which multiplies two matrices together, if possible; an overlap function which overlaps two matrices together. The augment function takes two matrices A and B of size mlxn1 and m2xn2, respectively, and produce a new matrix C of size mLxnL, where mL (resp. nL) is the largest between m1 and m2 (resp. n1 and n2). The values of C will either come from the original matrices by overlapping matrix B over matrix A. Wherever a value is not available it initialized to default value 0. For example: If you overlap two matrices A of size 4x2 and B of size 3x5, the resulting matrix C is of size 4x5. 2167 3339 23 13 63 79 B= 82651 39123 57314 C = A overlap B = 82651 39123 57314 79000

how to write a method that reads in any csv file and extracts the data from the csv file into header and the remaining data using the csv module, and stores them in instance variables. also how to write a code to handle potential errors with file content such as empty file and file not found in python?

Need urgent help with Python Decorator creation Never used python decorator before Answer the following questions in the Python decorator context. Your answers should be written in a Markdown file. The quality of answers matters!! What is higher-order function and how it is different from functor? What are First-class objects? What is the significance of functions being First-class objects? What are inner functions? What is the major benefit of inner functions and why is it important for decorator Why @ symbol is called syntactic sugar? What's the biggest advantage of using it when decorators are used? How would it help Python's weak OOP encapsulation of Class? (Hint: google "Python @Property decorator")

Please answer in python

Assume that you are designing a simple text editor (like Notepad) that supports inserting text, copy, paste and editing for any size file (including book-length files). Between the String objects and StringBuffer objects, which one is more appropriate and why? O String, because StringBuffer is read-only String, because it will execute more efficiently String, because only simple operations are needed StringBuffer, because it allows for changing the characters stored in the object StringBuffer, because it has copy and paste methods

I have to create a program file using python. I have created another program that would correlate with this code. I don't where to start. I will attach my program and the instructions. Create a file that has the data for at least five points. You can use notepad to make your file. Each line in the file should have each point’s lat and lon coordinates and a description. It could look like this: 100.200, 123.456, Main Campus 120.33, 142.345, Montoya 153.23, 322.345, Rio Rancho 133.23, 143.345, STEMULUS Center 153.42, 122.345, ATC   (Note: The “Points.txt” file attached to the assignment can be used instead of creating your own file.)   In the main part of your program do the following: Create a list that you will use to collect the points. Something like pointsList = []. Read points in from a file. As you read lat lon and description from the file, use those values to create a point and add that point to a List. Something like: newPoint = GeoPoint(lat, lon, description)…
