1. What is output by the following C++ code segment? Assume myList is an initially empty linked list that can store floats. Draw the linked list (with head, nodes, and pointers) to show how it looks conceptually by the time the code completes executing.

FloatList myList;

myList.insertNode(5.25);

myList.insertNode(2.14);

myList.appendNode(9.11);

for (int x = 1; x < 4; x++)

   myList.insertNode(x * 0.1);

myList.deleteNode(2.14);

myList.displayList();

Output:

Exercise3: GuessingGame.cpp

• Write a program that plays a game where the computer generates a random number between 1 and 100, and then lets the computer guess the right number.

• For each guess the program should display “too high” or “too low”, and then adjust the min and max of the next guess accordingly until either the correct number is guessed (game won) or 10 guesses are made without finding the right number (game lost).

• When a game is won, display the number of guesses that were made to arrive at the correct answer.

• Allow the user to determine how many games are played.

• When the user wants to stop, display the total number of games played, the number of games won, the number of games lost, and the average number of guesses it took to find the correct number.

Write program that draws out a path based on the user input. The starting coordinates for the path is the middle of the DrawingPanel. Ask the user to enter an x and a y coordinate for a DrawingPanel. Your program will draw a line from the last coordinates to the current coordinates the user enters. If the user enters an x value or y value out of bounds of the DrawingPanel, then end the program.

2. Create two class, a student class, and a course class, take advantage of the codes provided in the class slides and sample codes. python

3. Create a student object for every student in the UD.txt (you can use a loop for this)

4. Create 6 course objects:

5. After the student user login to their account as we have done in lab 2. Display the following:

When students choose option A, should display the following, where # is the actual number of students enrolled in the class.

Let the students add or drop a classes as they wish. When they choose E, exit the program.

6. For option D, show the courses in the student’s course list.

7. The hard part. Since your program will end when user chose option E. You need to keep track the classes been added and dropped by each students, and who are actually in the classes. Therefore, based on your experiences in lab 3 and 4, create a SI.txt (student info) to store the courses in each student’s course list. Create CI.txt (course info) to store all the students enrolled in each course. This will be executed in the background every time when the user chose option E: Exit. When you run your program, and create your course objects, this information needs to be read into each student and course object. When a student log into his or her account, the student should be able to see what courses is in the course list by chose option D. The number of students in each course also need to be displayed in Option A.

What to do

This assignment is going to be pretty simple - we're just going compute frequency counts of certain colors in certain ranges (Histogram of the image).

Because there is no natural way of segregating RGB color ranges, we usually do this color by color. So you'll be computing frequency counts for individual color components individually.

The expectation is that you will write a function as described by a python function signature below (while you are free to do whatever you want, I think doing future parts of the assignment will be easier if the code is structured this way) -

Think about what happens when one is comparing images of different sizes -

• Lets say A is an 4 by 4 image where half of the colors are gray (rgb(128, 128, 128)), and the other half is white (rgb(255, 255, 255))
• When you compute frequencies for Red component, you'll find that 128 occurs 8 times and 255 occurs 8 times also.
• Lets say B is an 8 by 8 image where half of the colors are gray (rgb(128, 128, 128)), and the other half is white (rgb(255, 255, 255))
• When you compute frequencies for Red component, you'll find that 128 occurs 32 times and 255 occurs 32 times also.
• This would mean that images that are basically the same in terms of colors (both half gray and white), end up with different histograms.

To make sure similar images have similar histograms regardless of image size, it is good to normalise frequencies by dividing each frequency count by the total number of pixel in the image.

• After normalization, frequency for red 128 in A would be 8 / (4 * 4) = 0.5
• After normalization, frequency for red 128 in B would be 32 / (8 * 8) = 0.5
• You will be given an image as a text file in the format we've been using so far - assignment_files.zip
