Add 2 constructors to the Course class. One that takes no arguments and initializes the data to all 0s and (empty strings). And one constructor that takes all 4 arguments, one argument for each property and then sets the properties to these arguments that are passed in. Lastly change the main to use these new Constructors. You will not need to call the set functions any more, but do not remove the set functions from your class.

Main Code

Course c1;

c1 = new Course(323, Intro to Php, Intro to Php Programming, 4);

c1.display();
