Read the array elements from the keyboard and then display only the positive numbers. Exercise 3: The results of a student in a module M are calculated based on the his/her marks in 3 assessments: a. Lab exam with 30% weightage b. Assignment 1 with 35% weightage C. Assignment 2 with 35% weightage 1. Create a class StudentResults in which you add as attributes the results of the student in the three assessments as described above. 2. Add a method FinalResult which calculates and displays the total marks of the student in the module M 3. Add a method PassFail which calls the method FinalResult and displays Pass if the student has a total score greater than 50 and Fail if not. 4. Create the Principal program that creates two instances of the class StudentResults entitled $1 and S2. Ask the user to introduce from the keyboard the marks for the 3 assessments for S1 and S2. Display the final results of the students S1 and 52 by calling the methods FinalResult and PassFail for S1 and 52
