You created a Connect Four game that enables two players to play the game on the console. Rewrite the program using a GUI program. The program enables two players to place red and yellow disks in turn. To place a disk, the player needs to click on an available cell. An available cell is unoccupied and its downward neighbor is occupied. The program flashes the four winning cells if a player wins, and reports no winners if all cells are occupied with no winners.

GuessBirthday.py, gives a program for guessing a birthday. Create a program for guessing birthdays. The program prompts the user to check whether the date is in any of the five sets. The date is displayed in a message box upon clicking the Guess Birthday button.

    def __init__(self):
        print("A's __init__() invoked")

Write a program that simulates four cars racing. You should define a subclass of Canvas to display a car.

Design a class named Triangle that extends the GeometricObject class. The Triangle class contains:

• Three float data fields named side1, side2, and side3 to denote the three sides of the triangle.
• A constructor that creates a triangle with the specified side1, side2, and side3 with default values 1.0.
• The accessor methods for all three data fields.
• A method named getArea() that returns the area of this triangle.
• A method named getPerimeter() that returns the perimeter of this triangle.
• A method named __str__() that returns a string description for the triangle.

For the formula to compute the area of a triangle. The __str__() method is implemented as follows:

return "Triangle: side1 = " + str(side1) + " side2 = " +
            str(side2) + " side3 = " + str(side3)

Draw the UML diagrams for the classes Triangle and GeometricObject. Implement the Triangle class. Write a test program that prompts the user to enter the three sides of the triangle, a color, and 1 or 0 to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the triangle’s area, perimeter, color, and True or False to indicate whether the triangle is filled or not.

How do you define a class that extends a superclass? What is super()? How do you invoke the superclass’s initializer?

Write the trigonometric forms of the complex numbers.

$$(\sqrt3+i)(1+i)$$

Predict the empirical formula of the ionic compound that forms from aluminum and oxygen.

Mercury(I) is unusual in that it often forms an ion that links with another mercury(I) ion. Thus, two mercury(I) ions are linked together in a single unit. What is the charge on this double ion? Write the formula for the compound that is formed from this double ion and chlorine.

Under what circumstances is a file stream object’s ios::eofbit bit set? What member function reports the state of this bit?

Indeterminate Forms Show that the indeterminate forms $0^0$, $\infty^0$, and $1^{\infty}$ do not always have a value of 1 by evaluating each limit. \
