Need help with a c++ building block question! Nongraded Implement the copy assignment operator= for the StringVar class using the options given on the right side window. Place the code into the left side using the arrows. It is possible to get the test case correct but not complete NOTE: Be careful! There are decoys! The this pointer is used extensively.. Assume that StringVar.h has the following declaration: #include <iostream> class StringVar {public:StringVar() : max_length(20) { // Default constructor size is 20value = new char[max_length+1];value[0] = '\0';}StringVar(int size); // Takes an int for sizeStringVar(const char cstr[]); // Takes a c-string and copies itStringVar(const StringVar& strObj); // Copy Constructor~StringVar(); // Destructorint size() const { return max_length; } // Access capacityconst char* c_str() const { return value; } // Access valueint length() const { return strlen(value); } // Access lengthStringVar& operator= (const StringVar&…

Write a Python function Def readFloat(userPrompt) That displays a prompt string (followed by a space), then reads a floating-point number in, and then returns that number. Here are some examples of typical usage: salary = readFloat(“Please enter your salary:”) percentageRaise = readFloat(“what percentage raise would you like?”) - Using the readFloat function that you wrote, write a Python program that will accept any number of floating-point numbers. When the user prompts “done”, the program should report out all of the numbers entered, the count of the numbers entered, the sum of the numbers entered, and the average of the numbers entered.

Write a C++ program called CylinderVolume to calculate the volume of a cylinder. The volume of a cylinder is: V=πr2h where r is the radius and h is the height and π is PI = 3.14159 for our purposes Use C++ multi-file format and these functions: void WriteHeader() void Goodbye(); string CalcVolume(double radius, double height); //use the pow function for squaring void AskForDimensions(double &rRadius, double &rHeight); Declare the constant PI in the .cpp file with the function definitions. That is the only place it is needed. You could even declared it in the CalcVolume function to make it more local. The CalcVolume function will return a nicely formatted string that describes the input and the volume, including that we are calculating the volume of a cylinder. The string will be created with stringstream. Set the precision to 3 decimal places. In main(), Declare variables and start a do-while loop for the repeated play. Display the Header, ask the user for the dimensions and…
