For this assignment you need to create a ToDo list using Javascript, along with HTML and CSS.

Begin by creating a HTML page called todo.html. Then create a Javascript file called todo.js and link it in to the HTML page using a script tag. All Javascript for the assignment must be in the separate file. (For CSS, feel free to include styles in a style block at the top of the HTML page, or to link in CSS from a separate file).

On the todo.html page, create two blocks of content (see the attached diagram).

At the top of the page, create a HTML form with the label New Item.

• The form should contain two elements: a textarea and a submit button.
• The submit button should be disabled if there is no text in the textarea. Inputting text in the textarea should enable the button.
• If the submit button is clicked while enabled, a new item should be added to the Item List section below the form. Once the item is added, the textarea should be cleared.

Below the form, create a block with the label Item List. This block will initially be empty.

When the submit button in the form is clicked, a new sub-block of content ('item block') should be created containing the following:

• The text from the textarea in the form.
• A timestamp below the text. This timestamp should be in a user-friendly format showing date and time (down to minute) that the item was created. This should be auto-generated based on the computer's local time.
• A delete button in the upper right of the item block, floated to the right of the text. When the delete button is clicked, the entire item block should be deleted. (You can include an 'Are you sure' confirm dialog if you like.)

Additional item blocks should be appended after the first item in the list. Item blocks should stack vertically.

For the following infix expression, build the corresponding expression tree.

1.1 a*b

1.2 a+b*c

1.3 a+b*c/d-e

Perform pre-order and post-order traversal of the above binary expression trees. What relationship exists among these scans and prefix and postfix notation for the expression?

Given a number n, what is the largest gap between successive primes which are less than number n?

For example, if n = 12, the prime numbers less than 12 are: [2, 3, 5, 7, 11]. The largest gap between any two prime numbers in this list is 4, so the function would return '4'. >>>print(largestGap(12))

4

Write Python code to solve this problem, and include the following 3 test cases in your answer.

>>>print(largestGap(100))

8

>>>print(largestGap(1000))

20

>>>print(largestGap(10000))

1. Write a program that read a sequence of positive integer inputs and print the sum and average of the inputs. Assume that the user always enters a positive number (integer) as an input value or an empty space as a sentinel value. Please use the below to test your code [45 points]:

Enter an int value or empty string to end: 98

Enter an int value or empty string to end: 78

Enter an int value or empty string to end: 77

Enter an int value or empty string to end: 1

Enter an int value or empty string to end: 10

Enter an int value or empty string to end:

Sum: 264 Average: 52.8

2. Write a program that read a sequence of positive integers and print the number of odd inputs entered by the user. The sentinel value is an empty string. Use the following test case [48 points]:

Enter integer or empty string to end: 3

Enter integer or empty string to end: 2

Enter integer or empty string to end: 10

Enter integer or empty string to end: 5

Enter integer or empty string to end: 6

Enter integer or empty string to end: 7

Enter integer or empty string to end:

number of odd integers entered: 3

3.Write a program that read a sequence of positive integers and print the average value of all the odd integers entered by the user (hint: you need to compute the sum of all the odd integers first to calculate the average). Use the following test case [7 points]:

Enter an int value or empty string to end: 10

Enter an int value or empty string to end: 20

Enter an int value or empty string to end: 5

Enter an int value or empty string to end: 10

Enter an int value or empty string to end: 15

Enter an int value or empty string to end:

average : 10.0

Determine a suitable process model for the following projects. Also, you are required to provide a short justification along with the necessary assumptions

d) An enterprise software system where the stakeholders do not well understand requirements. Thus, requirements are expected to be extremely changeable due to external changes, changing expectations, changes in the budget and the rapid change in technology.
e) Children learning mobile application. The stakeholders are concerned about the user interface more than the functionality of the application.

Answer the following questions about Windows registry:

1) Name at least four actions that trigger automatic registry changes.

2) Describe an indirect method of backing up the registry that backs up much more, as it creates a snapshot of the Windows installation minus the user's data. This also occurs on a regular basis by default in Windows.

3) In your own words define the Windows registry.

4) Describe the locations in Windows 10 of the options referred to in this chapter as user options and power options, comparing their location to where they were found in Windows 7.

5) Describe and compare Sleep and Hibernate.

6) Describe a safe method to modify the system startup settings for Windows.

7) Describe plug-and-play.

8) Your computer will not boot up normally and boots into Safe Mode. You suspect the problem is with a new device you installed. What utility should you open in Safe Mode and what should you look for?

9) What does it usually mean when Device Manager puts a device under a type node named "Other Devices?"

10) What will occur after you install a compatible driver for a device previously classified by Device Manager under Other devices?

write code data structure using  c language

You will build a system to manage patients’ data in a hospital. The hospital patient management system stores specific information in the form of health record to keep track of the patients’ data. Your program should read the information from a file called “patients.txt” that should be on the following format

: Patient Name#Gender#Date of admission#Date of birth #Illness#Address (City)#Blood type

Your program should be able to do the following tasks: Options: 1. Read data: read the data of the patients from the file.

2. Create linked list: create a linked list.

3. Sort data: use Radix sort to sort the data based on the patients’ names.

4. Add patient: add a new patient.

5. Update patient: update patient’s information.

6. Delete patient: soft delete (explained below).

7. Search for patients a. Name b. Date of birth

8. List patients a. All patients b. Category (i.e., illness) c. City d. Discharged (Patients who were deleted from the system)

9. Export medical report: export XML file following medial health record standards.

10. Exit: exit from the system and store the information back to the file.

6.40 LAB: Warm up: Text analyzer & modifier (1) Prompt the user to enter a string of their choosing. Output the string. (1 pt) Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. (2) Complete the GetNumOfCharacters() function, which returns the number of characters in the user's string. We encourage you to use a for loop in this function. (2 pts) (3) In main(), call the GetNumOfCharacters() function and then output the returned result. (1 pt) (4) Implement the OutputWithoutWhitespace() function. OutputWithoutWhitespace() outputs the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'. Call the OutputWithoutWhitespace() function in main(). (2 pts) Ex: Enter a sentence or phrase: The only thing we have to fear is fear itself. You entered: The only thing we have to fear is fear itself. Number of characters: 46 String with no whitespace: Theonlythingwehavetofearisfearitself.

In C++ Please
