Concept explainers
a)
To create the updateCount() function, to count the total of the number of characters that the user has typed into the comment text area box and declare the commentText variable inside the updateCount() function in the bw_review.js file.
b)
To write code statement to call the countCharacters0 function within the commentText as the parameter value to calculate the number of characters in commentText and to store the value in the charCount variable inside the updateCount() function in the bw_review.js file.
c)
To declare the wordCountBox that references the wordCount input box inside the updateCount() function in the bw_review.js file.
d)
To change the value stored in the wordCount input box to the text string charcount/1000 inside the updateCount() function in the bw_review.js file.
e)
To change the charCount variable if its value is greater than 1000 , change the style of the wordCount input box to a white font on a red background, otherwise set the style to a black font on a white background inside the updatecount() function in the bw_review.js file.

- Consider the following program that counts the number of spaces in a user-supplied string. Modify the program to define and use a function, countSpaces, instead. def main() : userInput = input("Enter a string: ") spaces = 0 for char in userInput : if char == " " : spaces = spaces + 1 print(spaces) main()arrow_forwardWhat is the python code for the function def readFloat(prompt) that displays the prompt string, followed by a space, reads a floating-point number in, and returns it. Here is a typical usage: salary = readFloat("Please enter your salary:") percentageRaise = readFloat("What percentage raise would you like?")arrow_forwardassume python does not define count method that can be applied to a string to determine the number of occurances of a character within a string. Implement the function numChars that takes a string and a character as arguments and determined and returns how many occurances of the given character occur withing the given stringarrow_forward
- Consider the ER diagram of online sales system above. Based on the diagram answer the questions below, a) Based on the ER Diagram, determine the Foreign Key in the Product Table. Just mention the name of the attribute that could be the Foreign Key. b) Mention the relationship between the Order and Customer Entities. You can use the following: 1:1, 1:M, M:1, 0:1, 1:0, M:0, 0:M c) Is there a direct relationship that exists between Store and Customer entities? Answer Yes/No? d) Which of the 4 Entities mention in the diagram can have a recursive relationship? e) If a new entity Order_Details is introduced, will it be a strong entity or weak entity? If it is a weak entity, then mention its type?arrow_forwardNo aiarrow_forwardGiven the dependency diagram of attributes {C1,C2,C3,C4,C5) in a table shown in the following figure, (the primary key attributes are underlined)arrow_forward

You can think of a tile as a square on the board on which the game will be played. We will come back to this class later. For the moment you can leave it empty while you work on creating classes that represents characters in the game. • Write an abstract class Fighter which has the following private fields: - A Tile field named position, representing the fighter's position in the game. A double field named health, representing the fighter's health points (HP). An int field named weaponType, representing the type of weapon the fighter is using. This value is used to rank different weapon types: higher values indicate higher weapon ranks. -An int field named attackDamage, representing the fighter's attack power. The class must also have the following public methods: 3 A constructor that takes as input a Tile indicating the position of the fighter, a double…arrow_forward
