Adding multiple events in an array of elements using 'querySelectorALL' in JavaScript?
In my HTML, i already have three Divs.
In my script section, this is my code:
for (var i = 0; i < box.length; i++) {
box[i].addEventListener("mouseover", function () {
box.style.backgroundColor = "blue";
});
}
box.addEventListener("mouseout", function () {
box[i].style.backgroundColor = "pink";
});
Ok so based on that code snippet, am trying to add a mouseover and mouseout events in each element so that when I hover on and off each div they change color. But it doesn't seem to work. Any advice on how I can make this work?
It looks like there are a couple of issues with your code. Here are some suggestions on how to fix them:
Use querySelectorAll to select all the div elements:
javascript
var box = document.querySelectorAll("div");
In your loop, you need to refer to the current element using this:
javascript
for (var i = 0; i < box.length; i++) {
box[i].addEventListener("mouseover", function () {
this.style.backgroundColor = "blue";
});
box[i].addEventListener("mouseout", function () {
this.style.backgroundColor = "pink";
});
}
In the mouseover and mouseout event listeners, you need to refer to the current element using this. Also, you need to set the backgroundColor property of the current element (this), not the box variable.
Putting it all together, your updated code should look like this:
javascript
var box = document.querySelectorAll("div");
for (var i = 0; i < box.length; i++) {
box[i].addEventListener("mouseover", function () {
this.style.backgroundColor = "blue";
});
box[i].addEventListener("mouseout", function () {
this.style.backgroundColor = "pink";
});
}
With these changes, you should be able to hover over and off each div to change its background color.
Answer:
The issue with your code is that you are trying to set the background color of the entire box element when you should only be changing the background color of the current element that is being hovered over or moused out.
To fix this, you can modify your code to use the this keyword inside the event listener function to refer to the current element that is being hovered over or moused out. Here's the updated code:
// Get all the box elements
var box = document.querySelectorAll(".box");
// Loop through each box element and add mouseover and mouseout event listeners
for (var i = 0; i < box.length; i++) {
box[i].addEventListener("mouseover", function () {
this.style.backgroundColor = "blue";
});
box[i].addEventListener("mouseout", function () {
this.style.backgroundColor = "pink";
});
}
In this updated code, we are using the this keyword to refer to the current element that is being hovered over or moused out. We are also setting the background color of the current element using the style.backgroundColor property, which ensures that only the current element's background color is changed.
Note: Make sure that your HTML elements have the class box in order for the querySelectorAll method to select them correctly.

Falling Distance
When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period:
d = ½ gt2
The variables in the formula are as follows:
d is the distance in meters
g is 9.8 (the gravitational constant)
t is the amount of time in seconds the object has been falling
Your program will calculate the distance in meters based on the object’s falling distance.
Modularity: Your program should contain 2 functions:
main – will call the falling_distance function in a loop, passing it the values 1 – 10 as arguments (seconds the object has been falling). It will display the returned distance.
falling_distance – will be passed one parameter which is the time in seconds the object has been falling and will calculate and return the distance in meters. falling_distance should be stored in a separate file (module) called distance.py You will import distance before your main function in your original program file.
Input Validation: None needed
Output: Should look like this:
Time Falling Distance
-----------------------------
1 4.90
2 19.60
3 44.10
4 78.40

How can i write void function that takes three arguments by reference. Your function should modify the values in the arguments so that the first argument contains the largest value, the second the second-largest, and the third the smallest value?
Answer:
void sort_three_numbers(int& num1, int& num2, int& num3) {
if (num1 < num2) {
std::swap(num1, num2);
}
if (num2 < num3) {
std::swap(num2, num3);
}
if (num1 < num2) {
std::swap(num1, num2);
}
}
Explanation:
In this implementation, we first compare num1 and num2, and swap them if num1 is smaller than num2. Then we compare num2 and num3, and swap them if num2 is smaller than num3. Finally, we compare num1 and num2 again, and swap them if num1 is smaller than num2. After these comparisons and swaps, the values of the arguments will be modified so that num1 contains the largest value, num2 contains the second-largest value, and num3 contains the smallest value.
To use this function, you can call it with three integer variables:
int num1 = 10;
int num2 = 5;
int num3 = 3;
sort_three_numbers(num1, num2, num3);
std::cout << num1 << " " << num2 << " " << num3 << std::endl; // prints "10 5 3"

Write a SQL query to display the Name of all those employee whose ENAME Field
contains 4 th character as ‘S’ from the table EMPLOYEE.
Answer:
The SQL query to display the name of all employees whose ENAME field contains the 4th character as 'S' from the table EMPLOYEE is:
SELECT NAME
FROM EMPLOYEE
WHERE ENAME LIKE '___S%';
Explanation:
In this query, we use the LIKE operator to match the pattern. The underscore symbol (_) matches any single character and the percentage symbol (%) matches any sequence of zero or more characters. So, the pattern '___S%' matches any string that has 'S' as the fourth character.
Write a program that find the average grade of a student. The program will ask the Instructor to enter three Exam scores. The program calculates the average exam score and displays the average grade.
The average displayed should be formatted in fixed-point notations, with two decimal points of precision. (Python)
Answer:
# Prompt the instructor to enter three exam scores
score1 = float(input("Enter the first exam score: "))
score2 = float(input("Enter the second exam score: "))
score3 = float(input("Enter the third exam score: "))
# Calculate the average exam score
average_score = (score1 + score2 + score3) / 3
# Calculate the average grade based on the average exam score
if average_score >= 90:
average_grade = "A"
elif average_score >= 80:
average_grade = "B"
elif average_score >= 70:
average_grade = "C"
elif average_score >= 60:
average_grade = "D"
else:
average_grade = "F"
# Display the average grade in fixed-point notation with two decimal points of precision
print("The average grade is: {:.2f} ({})".format(average_score, average_grade))
Explanation:
Sample Run:
Enter the first exam score: 85
Enter the second exam score: 78
Enter the third exam score: 92
The average grade is: 85.00 (B)
The given Python program determines the corresponding letter grade based on the average score, and then displays the average score and grade with the desired formatting.
What is Python?
Python is a high-level, interpreted programming language that was first released in 1991. It is designed to be easy to read and write, with a simple and intuitive syntax that emphasizes code readability. Python is widely used in various fields such as web development, data science, machine learning, and scientific computing, among others.
Python Code:
# Prompt the user to enter three exam scores
exam1 = float(input("Enter score for Exam 1: "))
exam2 = float(input("Enter score for Exam 2: "))
exam3 = float(input("Enter score for Exam 3: "))
# Calculate the average exam score
average = (exam1 + exam2 + exam3) / 3
# Determine the letter grade based on the average score
if average >= 90:
grade = 'A'
elif average >= 80:
grade = 'B'
elif average >= 70:
grade = 'C'
elif average >= 60:
grade = 'D'
else:
grade = 'F'
# Display the average score and grade
print("Average score: {:.2f}".format(average))
print("Grade: {}".format(grade))
In this program, we use the float() function to convert the input values from strings to floating-point numbers. We then calculate the average score by adding up the three exam scores and dividing by 3. Finally, we use an if statement to determine the letter grade based on the average score, and we use the .format() method to display the average score and grade with the desired formatting. The :.2f notation in the format string specifies that the average score should be displayed with two decimal places.

What is present in all HDLC control fields?
Group of answer choices
Code bits
N(S)
N(R)
P/F bit
Answer: Code bits.
Explanation:
HDLC (High-level Data Link Control) is a protocol used for transmitting data over a communication link. The HDLC frame consists of several fields, including the control field, which contains information about the flow and control of data. The control field in HDLC always includes three code bits, which identify the type of frame and the status of the communication. These code bits are always present in the control field, regardless of the type of frame or the data being transmitted. The other fields in the control field, such as N(S) and N(R), are used for sequence numbering and acknowledgment of frames, respectively, but they may not be present in all frames. Therefore, the correct answer is "Code bits."
Arithmetic Instructions
Using only registers (no input) add 1 + 2 and display the result. You can move the result to a variable then print it.
Answer:
Assuming we have a register for holding the result, the following assembly code will add 1 and 2 together and store the result in the register, then print the result to the console:
mov eax, 1 ; move the value 1 into the eax register
add eax, 2 ; add the value 2 to the eax register
mov ebx, eax ; move the value in eax into the ebx register
; At this point, ebx contains the result of 1 + 2
To print the result, we can use system calls. The specific system calls required will depend on the operating system being used. Here is an example using the Linux system call interface:
mov eax, 4 ; system call number for "write" (printing to console)
mov ebx, 1 ; file descriptor for stdout
mov ecx, ebx ; pointer to the string to be printed
mov edx, 1 ; length of the string to be printed (in bytes)
int 0x80 ; call the kernel to perform the write operation
; convert the result to a string and print it
add ebx, 48 ; convert result to ASCII code for printing
mov ecx, ebx ; move result to ecx for printing
mov edx, 1 ; length of the string to be printed (in bytes)
mov eax, 4 ; system call number for "write" (printing to console)
int 0x80 ; call the kernel to perform the write operation
Explanation:
This will print the result of 1 + 2 to the console as the character "3".

cout << "True, at least one character is equal to " << x << "." << endl;
}
else {
cout << "False, all the characters are not equal to " << x << "." << endl;
}
return 0;
}
Explanation:
The function ContainsSome() iterates through each character in the input string and checks if it is equal to the character parameter x. If a match is found, the function immediately returns true. If no matches are found, the function returns false after all characters have been checked.

Give an example that show different features of string slices. Describe the feature illustrated by each example.
Answer:
Here are some examples that illustrate different features of string slices:
Example 1: sentence = "The quick brown fox jumps over the lazy dog."
print(sentence[4:9])
Output: quick
This example shows how to use string slices to extract a substring from a larger string. The slice [4:9] extracts the characters from index 4 (inclusive) to index 9 (exclusive) of the string sentence, which corresponds to the substring "quick".
Example 2: word = "Python"
print(word[1:5:2])
Output: yh
This example shows how to use string slices to extract a substring with a specified step value. The slice [1:5:2] extracts the characters from index 1 (inclusive) to index 5 (exclusive) of the string word, but only takes every second character, resulting in the substring "yh".
Example 3: text = "Hello, world!"
print(text[::-1])
Output: !dlrow ,olleH
This example shows how to use string slices to reverse a string. The slice [::-1] extracts the entire string text, but with a step value of -1, which reverses the order of the characters. The resulting string is "!dlrow ,olleH".

Explanation:
The program first prompts the user for the number of grades, then loops through that many times to get each grade from the user. If the grade entered is between 0 and 4, it is added to the grades vector and its value is added to total_points. Otherwise, a 0 is added to the grades vector instead.
After all grades have been entered, the program calculates the GPA by dividing total_points by the number of grades entered (making sure to check that num_grades is greater than 0 to avoid a divide-by-zero error).
Finally, the program loops through each grade in the grades vector, converts it to a letter grade, and outputs both the letter grade and the GPA. Note that fixed and setprecision(2) are used to format the GPA to two decimal places.
Here's a pseudocode version of the program:
Prompt the user to enter the number of grades to be entered
Read in the number of grades to be entered
Initialize a variable to hold the sum of the grades
Initialize a variable to hold the count of valid grades
Initialize an empty array to hold the entered grades
Loop through the number of grades entered:
a. Read in the next grade
b. If the grade is between 0 and 4, add it to the sum of the grades and increment the count of valid grades
c. If the grade is not between 0 and 4, set it to 0
d. Add the grade to the array of entered grades
Calculate the GPA by dividing the sum of the grades by the count of valid grades
Output the calculated GPA
Loop through the array of entered grades:
a. Calculate the letter grade for each grade based on the grading scale provided in the prompt
b. Output the letter grade for each grade
Note: It's important to validate the input grades to ensure they fall within the accepted range of 0-4. This is why step 6c is included, and why any invalid grades are set to 0. Additionally, some schools or institutions may use different grading scales, so it's important to verify that the provided grading scale matches the one being used before implementing this program in a real-world scenario.
Rewrite the following statements using augmented assignment operators:
quantity = quantity + 1
days_left = days_left − 5
price = price * 10
price = price / 2
show step by step work
Using augmented assignment operators, the following statements have been rewritten:
quantity++;
days_left -= 5;
price *= 10;
price /= 2;
Define the term augmented assignment operators.
Augmented assignment operators are shorthand operators used in computer programming to perform an arithmetic operation on a variable and assign the result back to the same variable in a single step. They combine the arithmetic operator with the assignment operator to create a shorter and more readable syntax for performing the operation. Examples of augmented assignment operators include += for addition and assignment, -= for subtraction and assignment, *= for multiplication and assignment, and /= for division and assignment. The use of augmented assignment operators can simplify code and make it easier to read and understand.
Using augmented assignment operators, the following statements have been rewritten:
quantity += 1;
This statement increments the value of quantity by 1 using the += operator, which is equivalent to the original statement quantity = quantity + 1.
days_left -= 5;
This statement subtracts 5 from the value of days_left using the -= operator, which is equivalent to the original statement days_left = days_left - 5.
price *= 10;
This statement multiplies the value of price by 10 using the *= operator, which is equivalent to the original statement price = price * 10.
price /= 2;
This statement divides the value of price by 2 using the /= operator, which is equivalent to the original statement price = price / 2.
Therefore, the augmented assignment operator provides a shorthand way of performing the operation and assigning the result back to the same variable in a single step.
