Complete the code for the Student class method called void loadStudent(...) that receives a single string parameter. This string parameter will contain student details in the following format: ’Name’,’Surname’,’Email’,’Age’,’Student Number’ Write the code to separate the string and assign the correct values to the Student class members. Create an overloaded > (greater than) operator in the Student class. The operator will compare the age of two student objects and return the object with the greater age. In main.cpp create a non member function named isFemale. This function will receive as parameter a pointer to a student object. If the last two numbers of the student number is valid numbers (Must be between 0 and 9) the function will return true. Otherwise the function will return false. Overload the default constructor for Student to receive a single string parameter. This string parameter will contain student details in the following format:…
1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7). As per regulations, a 5.5 becomes a 6. If the student did not pass both the assignments (>= 95…
Java Programming: Write a static method named urgentAndIncomplete. Write the method as if it is in Main.java (not part of the ToDoItem class). The method should: Accept three ToDoItem references as parameters, and Return an int. Count how many of the ToDoItems meet two criteria: A priority greater than 3 Not completed The method should return how many of the parameters meet these criteria. That will be either 0, 1, 2, or 3.

Modify the student class presented in this chapter as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Overload the constructor such that each test score is assumed to be initially zero. Provide a method called setTestScore that accepts two parameters: the test number (1 through 3) and the score. Also provide a method called getTestScore that accepts the test number and returns the appropriate score Provide a method called average that computes and returns the average test score for this student. Modify the toString method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods. (Java)

Modify the Car class example and add the following: A default constructor that initializes strings to “N/A” and numbers to zero. An overloaded constructor that takes in initial values to set your fields (6 parameters). accel() method: a void method that takes a double variable as a parameter and increases the speed of the car by that amount. brake() method: a void method that sets the speed to zero. To test your class, you will need to instantiate at least two different Car objects in the main method in the CarDemo class. Each of your objects should use a different constructor. For the object that uses the default constructor, you will need to invoke the mutator methods to assign values to your fields. Invoke the displayFeatures() method for both objects and display the variables. Demonstrate the use of the accessor method getColor() by accessing the color of each car and printing it to the console. Use the method accel to increase the speed of the first car by 65 mph. Use…
Python Code: Write a class called Person with a constructor that takes two arguments, name and age and the saves these as attributes Write a method in this called print_person that prints out this information the console Confirm that you did it properly by instantiating an object called p1 and calling the method on the object. Lastly, extend the constructor by adding functionality that checks the input name only contains letters (no numbers allowed).
