Given main(), complete the Artist class (in files Artist.h and Artist.cpp) with constructors to initialize an artist's information, get member functions, and a PrintInfo() member function. The default constructor should initialize the artist's name to "unknown" and the years of birth and death to -1. PrintInfo() displays "Artist:", then a space, then the artist's name, then another space, then the birth and death dates in one of three formats: Answer in c++ (XXXX to YYYY) if both the birth and death years are nonnegative (XXXX to present) if the birth year is nonnegative and the death year is negative (unknown) otherwise Complete the Artwork class (in files Artwork.h and Artwork.cpp) with constructors to initialize an artwork's information, get member functions, and a PrintInfo() member function. The default constructor should initialize the title to "unknown", the year created to -1. PrintInfo() displays an artist's information by calling the PrintInfo() function in the Artist class,…

pizzaStats Assignment Description For this assignment, name your R file pizzaStats.R For all questions you should load tidyverse and lm.beta. You should not need to use any other libraries. Load tidyverse with suppressPackageStartupMessages(library(tidyverse)) Load lm.beta withsuppressPackageStartupMessages(library(lm.beta)) Run a regression predicting whether or not wine was ordered from temperature, bill, and pizza. Assign the coefficients of the summary of the model to Q1. The output should look something like this:                      Estimate    Std.

Java programming please type the code    For this problem set, you will submit a single java file named Homework.java. You are supposed to add the functions described below to your Homework class. The functional signatures of the functions you create must exactly match the signatures in the problem titles. You are not allowed to use any 3rd party libraries in the homework assignment nor are you allowed to use any dependencies from the java.util package besides the Pattern Class.  When you hava completed your homework, upload the Homework.java file to Grader Than. All tests will timeout and fail if your code takes longer than 10 seconds to complete. ProtectedFunction(string, int) This is a protected non-static function that takes a String and an int as its arguments and returns nothing. You don't need to put any code in this function, you may leave the function's code empty. Don't overthink this problem. This is to test your knowledge on how to create a non-static protected function.…
