Edit question USING C++ *Please explain in comments in the code of what you are doing and why Implement the GradedActivity class below. class GradedActivity { private: double score; public: GradedActivity() { score = 0.0; } GradedActivity(double s) { score = s; } void setScore(double s) { score = s; } double getScore() { return score; } char getLetterGrade() const; }; Create a new class Assignment which is derived from GradedActivity. It should have three private member ints for 3 different parts of an assignment score: functionality (max 50 points), efficiency (max 25 points), and style (max 25 points). Create member function set() in Assignment which takes three parameter ints and sets the member variables. It should also set its score member, which is inherited from GradedActivity, using the setScore() function, to functionality + efficiency + style. Signature: void Assignment::set(int, int, int) Create a main program which instantiates an Assignment, asks the user for its…

Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value. Ex: If the input is 15876, then the output is: The value in the tens place is: 7 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 GHE 14 15 16} public static void main(String[] args) { new Scanner(System.in); } Scanner scnr int userValue; int tensDigit; int tempVal; userValue = scnr.nextInt(); Your code goes here */ 11 System.out.println("The value in the tens place is: + tensDigit);
