Answer 1

Answer:

b. There are three objects created of Student class and they each have their own memory locations. The GetDetails() function is invoked for only the stud object of the class Student.

Meaning, the value of the data member in Student class can be different for newStud and stud. Even though all the objects can access the GetDetails() function, only the stud object called the GetDetails() function, stud.GetDetails();
