Fundamentals of Object-Oriented Programming - C++ - Friends - Functional Notation

The tutorial explains how to modify a distance class to include a friend function that calculates the square of a distance in square feet. It covers defining the function with a float return type, passing a distance object, and performing calculations to convert feet and inches into a floating point number. The tutorial demonstrates how to implement this function in the main program, create a distance object, and print the results, showing the distance and its square in square feet.

Describe the process of creating a distance object and using it to find the square feet.

What output is expected when the program is run with the distance of four feet and seven inches?
