Technology College Muscat hired you as a programmer to automate their manual Student Registration System. The college requires you to develop a C++ program to manage their Students' personal and academic record. You are required to develop a C++ program using C++ structures, arrays, and user defined functions. The college stores each student's full name, a maximum of 30 character long, student's age, numeric student's ID number of 8 digits long, student's modules enrolled and student's module result. You are required to implement 3 different functions, a function to get/input all the data of a student from a user. A function to get/input student's modules and result against each module and to calculate average marks of each students, and a function to display all students' personal and academic data. You are required to demonstrate storing of 5 students and displaying their stored data with average marks. You are also required to calculate and display the overall result analysis for 5…

Which of the following statement(s) is/are true for bagging and boosting? A) Bagging: Weak learners are built in parallel Boosting: Weak learners are built in sequence one after the other B) Bagging: More weight to those weak learners with better performance Boosting: Each weak learner has equal weight in the final prediction. C) Bagging: Samples are drawn from the original dataset with replacement to train each individual weak learner Boosting: Subsequent samples have more weight of those observations which had relatively higher errors in previous weak learners D) Bagging: Random forest is a special type of bagging technique Boosting: Adaboost is a special type of boosting technique

Question 1: Use MapReduce framework to convert the set of written book reviews to quantitative ratings of certain criteria. The output is the average of all numeric ratings of the book criteria. Reviewer1: Book A: I love reading it. The story is interesting, the writing is very good. Reviewer2: Book A: the story is amazing, however, the writing can be more entertaining. Reviewer3: Book B: the story is interesting, the writing is entertaining, I like reading it. Note: no standard answer since you decide the map function Question 2: Assume there are two files each of which contains city names and their recorded temperatures (note that each file might have the same city represented multiple times) as follows: File 01: (Cheney, 20), (Spokane, 25), (Seattle, 31), (Cheney, 14), (Spokane, 23) File 02: (Cheney, 18), (Seattle, 33), (Spokane, 32), (Seattle, 29), (Spokane, 30) Given these two files as the input, illustrate the Splitting, Mapping, Shuffling, Reducing, and Final Result steps (in…
