Description Write a short program that will define a function called make_book that will have 3 parameters: ● book_title book_author] book_length with a default value of 100 It will return a dictionary with the keys 'title', 'author', and 'length'. You will then call this function 2 times (not in a loop): • The first time specifying all parameters by order: Ulysses by James Joyce with 762 pages • The second time specifying the title and author by keyword: The Odyssey by Homer And print the dictionary returned by the function in a simple print statement. Specification • You should submit a single file called MidtermExam3.py • It should follow the submission standards outlined above. The assignment name will be Midterm Exam 3 • Each print statement should be sent a single f-string as an argument or nothing at all. For example: o Don't do this: [print("My variable is ", myvar1) o This is ok: print (f"My variable is {myvar1}")) o This is ok: print()

Language: C++ Subject: OOP Task:You have to write a program to store information of university students. There can be many students in university, so you can make a Student class and objects of class Student to store information. The university is interested in storing information about student’s name, enrollment, department, class, CGPA and gender. You can store this information as data member values for each object. But as you already know you cannot directly access data members of a class, so you need to make member functions to access data members. You can make as many member functions as you want. There are no restrictions. The University is interested in knowing the student’sname with highest CGPA in a specific class. For example if you entered information of 10 students from class BSIT 2 and information of 5 students from class BSIT 3, and it is asked to find name of student with highest CGPA in BSIT 2 then your program must be able to find details of highest CGPA student from…

Part 3: Time for a Financial Checkup Complete the function financial_checkup, which takes a dictionary representing your monthly budget for certain categories of expenditures (budget), and a dictionary that represents how much you actually spent in each category (outlays). The function then creates and returns a new dictionary of those categories in which you overspent and the excess amount. Specifically, the returned dictionary maps the category name to the amount of excess spending, given as a negative number. If a category appears in outlays, but not budget, we interpret this to mean that we budgeted $0 for that category, so the entire amount in outlays is considered to be excess spending. Example #1: budget: spent returned: {'food' -95, 'travel': -100} Example #2: budget: spent {'food': 125, 'gas': 75, 'travel': 400} {'food' 220, 'gas': 10, 'travel': 500} Example #3: {'food' 100, 'gas': 30} {'food' 220, 'gas': 10, 'travel': 500} returned: {'food": -120, 'travel': -500} {'drinks'…

Question Object Oriented Programming c++ Write a program that defines a class with a data member to holds a "serial number" for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you'll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each about its serial number. They should respond I am object number 2, and so on.
