- What are the rules for overloading operators? Select all that apply 1-Any operator can be overloaded as a friend function. 2-Any operator can be overloaded as a member function 3-An operator's precedence cannot change 4-An operator's number of operands (aka arity) cannot change. 5-Any operator that changes the invoking object must be a member function.arrow_forwardI don't want static data members or member functions.arrow_forwardUsing C++ Define the class called Student. The Student class has the following: Part 1) Private data members: name(string), age(int), units(int). The units represent the number of quarter units student is enrolled in. Define a default constructor as well as a constructor with parameters for the class Student. The class must have get and set functions for all private data members. The set function for the data member units must throw “out_of_range” exception if the number of units is not between 1 and 15. Include a function called tuition (double feePerUnit) that computes and returns the cost of registering for the number of units (in the private data member). The function receives the cost per unit as a parameter. Overload the operator (<<) to display student name and age. Test the class Student by writing a main program in which a Student object is created and displayed. Call the function tution(), you may pass any value as feePerUnit parameter to this function and display the…arrow_forward
