/*Create a class Student with six data members (Roll No., name , marks in English ,Maths and Science , total), write a program with init()
to initializes necessary data members , Calctotal() that calculates the total of the marks obtained int the three subjects and display()
that displays the details of the Students.
In main() create two objects of the class student and for each object invoke calctotal() and display().*/
