Exercise 3: Calculate the Student's Total Marks
In this exercise, you have to calculate a student's total marks using the concept of prototypes in constructor functions.
We'll cover the following
Problem Statement
A constructor function called Student
is given with the following parameters:
marks1
marks2
Important Note: Both
marks1
andmarks2
should be assigned to protected variables,_marks1
and_marks2
, during initialization.
Next, you have to define the following methods such that they can be shared by all object instances created:
-
getMarks(markNumber)
: a method which should return_marks1
ifmarkNumber
equals 1 and_marks2
ifmarkNumber
equals 2. -
calcTotal()
: the method should return the sum of_marks1
and_marks2
.
