READ THIS ASSIGNMENT CAREFULLY. THERE ARE A LOT OF DETAILED REQUIREMENTS. Create a C++ program that reads information about electronic components from the keyboard, stores that information using classes with inheritance, polymorphism and virtual functions then prints information about the components. You must implement this project using multiple header files and source files, with the header files containing declarations and inline functions and with the source files containing the implementations of the remaining functions. You may inline member functions for trivial member functions but must NOT inline all the member functions of the classes implemented in this project. Create a pure virtual base class to identify the functions that must be implemented by different electronic components. In this pure virtual base class, declare a virtual destructor and three pure virtual functions: • A pure virtual function to get the value of the electronic component, returning a value of type double. • A pure virtual function to get the units of the electronic component, returning a value of type string. • A pure virtual function to get the printable description of the electronic component, returning a value of type string. You must also overload the << operator so you can use “cout <<” with variables that are a type of electronic component. In the implementation of the overloaded operator<< you should call the pure virtual function that returns the printable description of the electronic component. Create a class, inheriting from the pure virtual electronic component class described above to hold information related to a resistor (a type of electronic component). You need to implement a destructor and the three virtual functions defined in the pure virtual electronic class described above. You need to add a constructor that takes one parameter, the value of the resistor. The value is of type double. The function that returns the printable description of the resistor should return a string consisting of the value of the resistor appended with “Ohm(s)”. Create classes, inheriting from the pure virtual electronic component class Page 2 of 6 You need to add constructors for each class that takes one parameter, the value of the component. The function that returns the printable description of the capacitor should return the a string consisting of the value of the capacity appended with “Farad(s)” and the function that returns the printable description of the battery should return a string consisting of the value of the battery appended with “Volt(s)”. For the main function, create an array or vector of pointers to electronic components. Prompt the user for which type of component they want to select or if they want to terminate the program. If the user selected a type of component, dynamically create an instance of that component, add it to the array or vector, and prompt the user for the value of the component. Do this repeatedly until the user elects to terminate the program. When the user elects to terminate the program, you should iterate through the array or vector of electronic components, calling the function on each object to get the printable description of each component and printing that to the screen. Then, make a second pass through the array or vector of electronic components, outputting information on the component using the following code fragment: cout << "Component " << count << " " << *components[index] << endl; Finally, delete all the dynamically allocated memory. You should be diligent in validating the input provided by the user and ensure you protect against unexpected input. The first line of the source code should be a comment including the following information:
Ensure your program is well documented, well structured, and uses meaningful variable names. Use multiple functions as necessary for good structure and readability. Sample Input and Output Here is some sample output, including the handling of erroneous data entered from the keyboard.

Hi Sorry I am unable to upload the zip or files.
Please create a Win32 console project in visual studio and add following files.

int componentChoice = 0;
do
{
cout<<"Please enter 1, 2, 3 or 4:" << endl << "1 - Enter information about a resistor" << endl << "2 - Enter information about a capacitor" << endl
<< "3 - Enter information about a battery" << endl << "4 - Print component information and terminate the program " << endl;
cin >> componentChoice;
if(componentChoice == 4)
{
// print all object's printdescription function
for(int index = 0; index < componentList.size(); index++)
{
componentList[index]->GetPrintDescriptionOfEComponent();
}
// iterate through vector and print like below
for(int index = 0; index < componentList.size(); index++)
{
int count = index + 1;
cout << "Component " << count << " " << componentList[index] << endl;
}
break;
}
else if( componentChoice >= 1 && componentChoice <= 3)
