Create a class hierarchy that performs conversions from one system of units to another. Your program should perform the following conversions, i. Liters to Gallons, ii. Fahrenheit to Celsius and ii. Feet to Meters The base class convert declares two variables, vall and val2, which hold the initial and converted values, respectively. It also defines the functions getinit() and getconv(), which return the initial value and the converted value. These elements of convert are fixed and applicable to all derived classes that will inherit convert. However, the function that will actually perform the conversion, compute(), is a pure virtual function that must be defined by the classes derived from convert. The specific nature of compute() will be determined by what type of conversion is taking place. Three classes will be derived from convert to perform conversions of Liters to Gallons (1 _to_g), Fahrenheit to Celsius (f to c) and Feet to Meters (f to_m), respectively. Each derived class overrides compute() in its own way to perform the desired conversion. Test these classes from main() to demonstrate that even though the actual conversion differs between 1_to_g, f_to_c, andf_to_m, the interface remains constant.

I need help with this assignment, I need to make a struct to implement a limited Python style list in C++. When you bootstrap the exercise, you will be given a main.cpp file, with a simple program written in it. The program declares a Python style list and appends several elements to it, before printing it out to the terminal. The file is where I would setup my code #ifndef PY_LIST_H #define PY_LIST_H #include <iostream> struct PyList { // Declare your vars here PyList(){ // Implement this } void append(int x){ // Implement this } void append(char x){ // Implement this } void append(float x){ // Implement this } ~PyList(){ // Implement this } }; std::ostream& operator<<(std::ostream& os, const PyList& pyList){ os << '['; // Complete this implementation os << ']'; return os; } #endif Here is the main.cpp file that it must be able to run and the float must not have floating zeros #include <iostream> #include "PyList.h"…

Write a C program that uses arrays and functions to implement a calculator for twooperands. Your calculator must have five principal operations, addition (  ), subtraction (  ),division (  ), multiplication (  ), and power (  ). In the beginning of the program, show the menuof operators to the user. When the user selects one of the operators, your program gets the valuesfor operand 1 and operand 2 from the user and saves them into an array. Then pass the array to thesuitable function to calculate the result. The operating functions must return the value to the mainprogram. The calculation stops when the user press “x”. Use a global variable to save the result oflast operation. Anytime that the user types “M”, the program shows the result of last operation.hint: Each mathematic operation must be a separate function. Your main program calls those functions.
