Instructions

In this assignment, you will modify the Beam class that is already provided. You will add some new functionality to the class by adding additional functions to the file beam.cpp. A header file beam.h with the data members and function prototypes is already uploaded. There is also a main program called main_hw.cpp that uses this new functionality. Do not modify either beam.h or main_hw.cpp. Start with your beam.cpp file and make additions to it. Compiling and running main_hw.cpp with your new beam.cpp class file will produce the output shown below. You can also test your class file after submission.

Your program must have the following:

An additional (overloaded) constructor function that takes 2 input float parameters, the length and depth in that order, and uses these values instead of the default values. Everything else will be the same as the default case.

A new accessor function call getWidth() that returns the width as type float.

A new operator << that takes a string and assigns it to a new private data member of type string.

A new accessor function called getName() that returns the name as a string.

Sample Output:

Width: 7.56 Name: Joe
