Create a class student containing data members:
a. Roll_no b. name c. marks1, marks2, marks3.
Write necessary member functions:
a. to accept details
of one students
b. to accept
details of all students
c. to display details
of one student
d. to display details
of all students
(Use Function
overloading).
