6. Given: class Pet { public: virtual void eat() { cout eat(); } What is the result of compiling and running the above program? m. The program compiles and crashes when it runs. i. The program compiles and runs, printing "Pet::eat" j. The program compiles and runs, printing "Cat::eat" The program compiles and runs to completion without printing anything. n. o. None of the above. k. The program fails to compile because the method eat is not marked virtual in Cat. I. The program fails to compile for some other reason.

please answer with proper explanation and step by step solution. Question: Program in python: Design a simple class called Dealership, that has two functions: buyCar(Car a) and sellCar(Car a). buyCar(Car a): Adds the car to the list of cars already in the dealership. sellCar(Car a): Removes the car from the list of cars already in the dealership. Note: Implementation of the Car class is not important for this question
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Ex: If the input is: 5 50 60 140 200 75 100 the output is: 50,60,75, The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75. For coding simplicity, follow every output value by a comma, including the last one. Such functionality is common on sites like Amazon, where a user can filter results. This is my code so far can you let me know what I'm doing wrong please! integers=[]amount_of_integers=int(input())for i in range(amount_of_integers): user_input=int(input()) integers.append(user_input)last_value=integers.pop()for i in…
The compiler will generate a(n) if you create a class that has no constructor at all.

Description: In a hypothetical class, students take two midterms and an optional final. If a student takes the final and gets in it a better score than the lowest of the two midterm scores, then the lowest midterm score would be replaced by the comprehensive final score. The overall score will then be calculated by averaging the three test scores. If the student does not take the optional final, the overall score is calculated using only the two midterm scores. Students’ exam scores are included in the “Question1” tab in the attached worksheet. Empty data entries for the optional comprehensive final means that the student did not take the optional final. Tasks: Task 1: In Question1_Module, code a function that requires midterm1 score, midterm2 score, and comprehensive final as inputs and calculate the overall score per the description above. Task 2: In Question1_Module, code a Sub that uses the function coded in task 1 to fill column ‘I’ of the worksheet and link this…
