Create a ‘DISTANCE’ class with the following:- feet (type int) and inches (type float) as data
members. Overloaded stream extraction operator (>>) for input and overload insertion operator
(<<) for output of class data members.
Write a main() to test all the functions in the class and follows the user to enter data, and
displays the data members that is entered by the user. The main() function should display an
appropriate thrown error message if user enter negative distance value from the command
prompt.

- In the class cashRegister, add the functions to overload the binary operators + and –to add and subtract an amount in a cash register; the relational operators to compare the amount in two cash registers; and the stream insertion operator for easy output. The class dispenserType, in the Programming Example “Juice Machine” in Chapter 10, is designed to implement a dispenser to hold and release products. In this class, add the functions to overload the increment and decrement operators to increment and decrement the number of items by one, respectively, and the stream insertion operator for easy output. Write a program to test the classes designed in steps 1 and 2. I have: cashRegister.h cashRegister.cpp dispenseType.h dispenserType.cppIn the class cashRegister, add the functions to overload the binary operators + and –to add and subtract an amount in a cash register; the relational operators to compare the amount in two cash registers; and the stream insertion operator for easy output.

- The stream insertion operator << can be overloaded with an operator function that takesan istream reference and a reference to a user-defined type as arguments and returns anistream reference. T/FThe stream extraction operator >> can be overloaded with an operator function thattakes an istream reference and a reference to a user-defined type as arguments and returns an istream reference T/FSuppose that you have the Object class Employee which is an object that contains Name, Surname and Payment with the respective set and get functions. You will create following functions on 'EmpRW' class, and create a main java class to call them. a. Write a java function that writes on a file named 'emp.txt' by using Formatter Class, this Employee Object. b. Write another java function that reads from the file 'emp.txt' and stores the data as an array of Instances of Employee object. C. Write a function that prints out the name, surname and maximum salary from the Employee list taken from the file. Now write the main java class that takes data by using Input Dialogs, and that uses all of above functions of 'EmpR W' class. e. Write the same functions in a and b by assuming the Employee Object class is serializable, on 'EmpSerR W' class. The name of the file to read and write should be 'emp.bin
- Regarding the code below, how would I write code to declare all class member functions in a separate "Pet.h" file? All class member functions need to be declared in the Pet.h header file and defined in the Pet.cpp file (below). #include <iostream> #include "Pet.h"using namespace std; //Class Definitionclass Pet { private: //Variable declarationstring Name, Type;int LevelOfHungriness;public: //Default ConstructorPet(){Name ="Buddy";Type ="dog";LevelOfHungriness=CONTENT_HUNGRY;}//Parametrized constructorPet(string n, string p, int l){Name =n;Type =p;LevelOfHungriness=l;}//Definition of TimePasses functionint TimePasses(){if(LevelOfHungriness < VERY_HUNGRY){LevelOfHungriness++;}return LevelOfHungriness;}//Definition of FeedPet functionint FeedPet(){LevelOfHungriness = NOT_HUNGRY;return LevelOfHungriness;}//definition of PrintInfo function void PrintInfo(){cout<<"A " << Type << " named " << Name << " who is hungry level " <<…write a python code named get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary. (Suppose we want to know the total number of cases reported on each date, so use x = 0.) >>> result, total_cases = get_total_cases(database, 0) >>> display_dict(result) 2021-05-19: 8 2021-05-20: 2 2021-05-21: 1 2021-05-22: 1 >>> print(total_cases)Implement a function writeEmpToFile that takes two arguments: a struct Employee pointer and a FILE *. It should write each field in order as an appropriate type. Note that you will probably want to write a length of the name before you write the characters of the name. By doing this, when you write the load function below, you can read the length of the string and use it to malloc a buffer of the proper size to hold the name. Because of the embedded name pointer, you CAN NOT write the Employee struct as a single struct. You will need to write it out field by field. You will want to write this as a binary file, not as a text file. Implement a SAVE command in your main loop that will save all the employees out to a file. The SAVE command should ask for a file name, similar to the way your FIND command asked for a name. Below is the work I have done so far that is required from the image but I have not been able to finish it and I need assistance with making the final changes that…

What is the difference between the set and multiset STL classes in Chapter 3? Group of answer choices The multiset class allows duplicate values in the container, whereas the set class requires unique values. The multiset class allows unique values in the container, whereas the set class requires duplicate values . The multiset class allows duplicate and unique values in the container, whereas the set class requires duplicate values. The multiset class allows duplicate values in the container, whereas the set class requires unique and duplicate values. They are using different name but identical .
