Constructor
Constructor is used for object creation and specifying some attributes. Look at this statement:
Student() is a constructor of class Student, so the student variable is now a Student object.
This simple constructor is using by default and creates an object only. But you can define a constructor that will initialize some object attributes.
student object now has name Robert and age 22.
The syntax of the constructor inside the class is following:
By object creating, you can pass some arguments and use them inside constructor. But note that skipped parameters will have undefined value. Look at the example and run it to see what happens.
Only name and age properties are defined in student object because of 2 arguments while student initialization.
Pass the arguments in order they are defined in constructor.
Task
Extend existing constructor with arguments for university and gpa attributes. After that, change the line of object initialization by adding 2 more arguements inside Student() statement.
