Programming languages: Consider the following record definitions that create two structures named,

Consider the following record definitions that create two structures named, Drug and Book. record (name string:dosage float;) Drug record (amount float:isbn string;) Book Now consider the following statements, which compile and execute successfully: 1:Drug d = new Drug (): 2:d name = "Losartan": 3:Book b = d: 4:b. amount = 13.80: Based on this example, briefly describe (a few sentences) the properties of the type system of the corresponding programming language. Pay attention to each of the statements since there are a number of obvious statements you can make
