Question

Define a class Student described as below:
Data members/instance variables : name,age,m1,m2,m3 (marks in 3 subjects), maximum, average
Member methods :

(i) A parameterized constructor to initialize the data members.

(ii) To accept the details of a student.

(iii) To compute the average and the maximum out of three marks.

(iv) To display the name, age, marks in three subjects, maximum and average.
Write a main method to create an object of a class and call the above member methods.
