Explanation:

All three of these manipulators control the appearance of floating-point numbers in output streams.

The three are:

The std::fixed stream manipulator is used to set a fixed number of decimal places in the output stream, regardless of the actual value of the number. This allows for consistent formatting of the output.

The std::setprecision manipulator is used to set the number of digits after the decimal point, allowing for more precise control of the output.

The std::showpoint stream manipulator is used to always display a decimal point, even if the value of the number is an integer.

Together, these manipulators provide the ability to control the exact appearance of floating-point numbers in the output stream.

The full task:

When using the stream manipulators from the stream library to control the appearance of floating-point numbers, there are three that always go together. If you need any one of them, you need all three.

Which three are they?

In order to handle an exception, the code that causes the exception must be placed within a try block.

To handle exceptions in programming, we use a try-catch mechanism. The try block is where we place the code that might throw an exception. This block is followed by one or more catch blocks that handle specific types of exceptions.

Inside the try block, if an exception occurs, the program will immediately jump to the catch block that matches the type of exception thrown. This allows us to gracefully handle errors and prevent the program from crashing.

Here's an example:

```
try {
  // Code that might cause an exception
  int result = 10 / 0; // Division by zero error
  // More code
} catch (ArithmeticException e) {
  // Exception handling code
  System.out.println("An arithmetic exception occurred!");
}
```

In this example, the code within the try block attempts to perform a division by zero, which results in an ArithmeticException being thrown. The catch block then catches this exception and executes the code inside it.

To summarize, the code that causes the exception must be enclosed within a try block in order to handle the exception properly.

No, you should not print a NULL character ('\0') in writeline function in C or C++.

In C and C++, strings are represented as arrays of characters terminated by a null character ('\0').

The null character is used to indicate the end of a string, but it is not intended to be printed or displayed as a visible character.

The writeline function to print a string, it automatically adds a newline character ('\n') at the end of the string.

This newline character serves as a delimiter for the current line and indicates that the next output should begin on a new line.

Adding a NULL character to the end of the string would be unnecessary and may cause unexpected behavior.

The writeline function, you should only print the characters in the string up to (but not including) the null terminator:

void writeline(const char × str) {

   for (int i = 0; str[i] != '\0'; i++) {

       putchar(str[i]);

   }

   putchar('\n');  // add newline character

}

This will print the string followed by a newline character, without including the null terminator in the output.

To create an event handler that opens a dialog box to alert the user to a change in the data saved to web storage using JavaScript, you should place the following statement in the blank:

`window.addEventListener('storage', function(e) { alert('Data saved in web storage has changed.'); });`

This code snippet listens for the 'storage' event and triggers an alert dialog box when there is a change in the data saved in web storage.

In this statement, we are using the addEventListener() method to register an event handler for the storage event. When this event is triggered, the function specified as the second argument will be executed.

Inside the function, we are checking if the event key matches the key for the data we are interested in (in this case, myData). If there is a match, we are displaying an alert dialog box to notify the user that the data has changed.

In layout view, the method used to edit text in a label control is by selecting the label and modifying its properties.

In layout view, a label control is a visual element that displays text or a caption for another control, such as a textbox or button, in a user interface. To edit the text displayed by the label control, you need to select the label in the layout view. This can be done by clicking on the label or by selecting it from the object hierarchy. Once the label is selected, you can modify its properties in the property grid or the properties window.

In the properties window, you can locate the property that represents the text displayed by the label. This property is usually called "Text" or "Caption." By changing the value of this property, you can edit the text displayed by the label control. Alternatively, you can also directly edit the text in the label by double-clicking on it or by selecting it and typing the desired text.

Overall, in layout view, the method to edit text in a label control involves selecting the label and modifying its text property either in the properties window or by directly editing the text within the label.

One possible solution in Python for this problem is as follows:

Define two empty sets to keep track of the rows and columns that contain drop points. Loop through each drop point and add its row and column to their respective sets.

Calculate the total number of rows and columns that have at least one drop point.

The maximum number of drop points that can be covered by flying over the terrain once is the maximum of these two values.

Here's the code:

def max_drop_points(drop_points):

   rows = set()

   cols = set()

   for point in drop_points:

       rows.add(point[0])

       cols.add(point[1])

   return max(len(rows), len(cols))

The function max_drop_points takes a list of tuples representing the coordinates of the drop points as its input and returns the maximum number of drop points that can be covered by flying over the terrain once. This solution has a time complexity of O(n), where n is the number of drop points, which is optimal.

a) Use binary search to check if A[mid] equals mid, recursively searching left or right half. b) Find the indices of p and q using binary search, and return the difference between their indices. Time complexity is O(log n).

a) The following is the pseudocode for finding an index i in sorted array A, where A[i]=i, using divide and conquer algorithm:

def find_index(A, left1, right1):

   if left1 > right1:

       return -1

   mid = (right1 + left1) // 2

   if A[mid] == mid:

       return mid

   if A[mid] > mid:

       return find_index(A, left1, mid - 1)

   return find_index(A, mid + 1, right1)

The algorithm recursively divides the array into halves until it finds an index i such that A[i] = i or the left1 index becomes greater than the right1 index. O(log n) is the time complexity of this algorithm.

b) The following is the pseudocode for finding the number of elements between p and q in sorted array B:

def find_elements_between(B, p1, q1):

   if p1> q1:

       return 0

   if B[p1] == B[q1]:

       return q1 - p1 + 1

   mid = (q1 + p1) // 2

   if B[mid] == p1:

       return q1 - mid

   if B[mid] == q1:

       return mid - p1

   return find_elements_between(B, p1, mid - 1) + find_elements_between(B, mid + 1, q1)

The algorithm recursively divides the array into halves until it finds elements p1 and q1 or the element at the middle index is equal to p1 or q1. Then it returns the number of elements between p1 and q1 using the indices obtained from the recursive calls.  O(log n) is the time complexity of this algorithm.

The first algorithm uses a modified binary search to search for the desired index i. The second algorithm uses binary search to locate p1 and q1, then returns the difference of their indices.
