Question

Write the C# code and make a screenshot of the output according to tasks given below:

Create a class named Prism with protected data fields named height and volume (Use double data type for the fields) [5 points]

Include public properties for each field. The Height and Volume properties should have get and set accessors. [5 points]

Add default constructor which sets the value of Height and Volume properties to 1 and 1 respectively. [5 points]

Add overloading constructor which takes the parameters of _height and _volume. Then assign these values to the corresponding properties. [5 points]

Add public method CalcArea() which returns the value of (Use double data type) [5 points]

Create a derived class named Square with private data fields named area and length. [5 points]

Include public properties for area field. The Area property should have get and set accessors. Set accessor for the Area should be assigned to the method CalcArea().[5 points]

Include public properties for length field. The Length property should have get and set accessors. Set accessor for the Length should be calculated using . [5 points]

In the main method write try and catch pair. Inside the try block declare and instantiate object named p1 from Prism class using default constructor and object initializer. Assign values of 10 and 0 to Volume and Height properties respectively. Inside the catch block catch any exception and display the type of the exception as well as the text “You tried to divide by zero which is impossible”. [10 points]

Write another try and catch pair. Inside the try block declare and instantiate object named s1 from Square derived class using default constructor and display the text “Input value for the volume>>>”, “Input value for the height>>>” and assign input values from the console to the corresponding properties of the object. Inside the catch block catch any exception and display the type of the exception as well as the text “You tried to input string instead of number”. [10points]

Run the program and input any text from console in order to cause conversion exception to be thrown by the program. Take a screenshot of the output you received in online compiler and paste it below. [Bonus 10 points]
