NP57 Meaning of the code

Question

Hi Guys

 

NP57   Meaning of the code

 

I got this program from the following website. I have problem in understanding the program.

 

• Bill.LeftShoe = new Shoe();
• Bill.RightShoe = new Shoe();

What do the above codes mean and what is the purpose of the above code. Because without these two codes program is producing same output. Anyone knows please explain the reason.
