Create a webpage A2-Task2.html. The webpage is displaying one image. Each time the user clicks the image, the image is changed to another one and one more 'globe' emoji is displayed under the image. When the number of 'globes' reaches five (5), all 'globes' are deleted (reset) and start to be displayed again. For example, the 6th time user clicks the image, one 'globe' is shown, the 7th time - two 'globes', and so on. Note: - You should use two images. Each time the user clicks on the image, the image is changing. If an image of "Seaside" is displayed it will change to "Mountain view", and opposite, if an image of "Mountain view" is displayed it will change to "Seaside". - The special character code for the 'globe' is "🌏".
Create a webpage A2-Task2.html. The webpage is displaying one image. Each time the user moves the mouse out of the image, the image is changed to another one and one more 'sun' emoji is displayed under the image. When the number of 'suns' reaches seven (7), all 'suns are deleted (reset) and start to be displayed again. For example, the 8th time user moves the mouse out of the image, one 'sun' is shown, the 9th time - two 'suns', and so on. Note: - You should use two images. Each time the user moves the mouse out of the image, the image is changing. If an image of "Winter" is displayed it will change to "Summer", and opposite, if an image of "Summer" is displayed it will change to "Winter". The special character code for the 'sun' is "☀". Put the source code of your website A2-Task2.html here. Make sure you also upload the A2-Task2.zip of all files below.
Given a list of employees, create a simple program that allows the user to insert, delete, display, and search an employee. The program should input 10 full names of employees with employee number as linked list. Also, a list of menus should be displayed. These menus are Insert, Delete, Display and Search. A. Insert - allows the user to insert one employee at a time with corresponding ID number which serves as their link. All employees to be inserted must be inserted at the end of the list. B. Delete – allows the user to delete the employee from the list C. Display – allows the user to display the list of employees D. Search - allows the user to find a certain employee These menus should be in loop once you test every operation based on the listed menu. Use linked list as a data structure in generating a list of employees, and Perform basic operations that can be applied in a linked list
***Please Answer with code*** Your goal is to create a PHP driven website for selling Computer Science textbooks. Your site MUST include the following: 1. An Index page which includes menus for different subjects (Networking, programming, security). 2. Each subject page must allow the user to select and order more than one book at a time. When the user has selected the book, they should be requested to enter their student id number to reserve the book. They can also select a check box, which "charges their account on file" for the book. This also allows them to have curb side pickup. If the user does not check the box, the site will let them know the book will be on reserve for them to pick up for the next 24 hours. Once the time expires the book will be returend to the shelve. 3. All information entered by the user must be verified. Check for: correct type (numbers/strings), missing information, invalid format (such as invalid student id format). An error message must display allowing…
