Code Example 17-1 class PayCalculator { private: int wages; public: PayCalculator& calculate_wages(double hours, double wages) { this->wages = hours * wages; return *this; } double get_wages() { return wages; } }; (Refer to Code Example 17-1.) What coding technique is illustrated by the following code? PayCalculator calc; double pay = calc.calculate_wages(40, 20.5).get_wages(); a. self-referencing b. function chaining c. dereferencing d. class chaining
Answer:
The answer is "Option b".
Explanation:
Function chaining is shown by this code, as the functions are called one after the other with one statement. Whenever you want to call a series of methods through an object, that technique is beneficial. Just because of that, you may give the same effect with less code and have a single given value only at top of the leash of operations.

Write a program that randomly chooses among three different colors for displaying text on the screen. Use a loop to display 20 lines of text, each with a randomly chosen color. The probabilities for each color are to be as follows: white 30%, blue 10%, green 60%. Suggestion: Generate a random integer between 0 and 9. If the resulting integer falls in the range 0 to 2 (inclusive), choose white. If the integer equals to 3, choose blue. If the integer falls in the range 4 to 9 (inclusive), choose green. Test your program by running it ten times, each time observing whether the distribution of line colors appears to match the required probabilities.

Write a recursive function called DrawTriangle() that outputs lines of '*' to form a right side up isosceles triangle. Function DrawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting.
Answer:
Code:-
# function to print the pattern
def draw_triangle(n, num):
# base case
if (n == 0):
return;
print_space(n - 1);
print_asterisk(num - n + 1);
print("");
# recursively calling pattern()
pattern(n - 1, num);
# function to print spaces
def print_space(space):
# base case
if (space == 0):
return;
print(" ", end = "");
# recursively calling print_space()
print_space(space - 1);
# function to print asterisks
def print_asterisk(asterisk):
# base case
if(asterisk == 0):
return;
print("* ", end = "");
# recursively calling asterisk()
print_asterisk(asterisk - 1);
# Driver Code
n = 19;
draw_triangle(n, n);
Output:-
# Driver Code n = 19;| draw_triangle(n, n);
I connected to an external hard drive to transfer some photos from my vacation. When I try to drag the photo, it bounces right back and does not transfer. What is the likely cause of this issue?
a. hard drive is full
b. photos were taken in a different country
c. USB port is broken
d. the file structure of the 2 hard drives are not compatible
The answer is D, What is the likely cause of this issue is that the file structure of the two hard drives are not compatible.
The file structure or file system, of a hard drive, tells the disk how to read, write and store information on the drive. Some file systems do not allow the disk to store any files and often do not display error messages. If we try to drag a file onto a hard drive with this kind of file structure, the action would simply not be performed. This can be fixed by formatting the disk partition into a new file system.
Option B states that the issue may be that the photos were taken in a different country. This is not the cause of the problem because regardless of where the pictures are taken, they are all stored in common formats such as:
JPEGPNGJFIFAny external hard drive capable of storing images will have the ability to receive files in these formats as well as many other image formats. For this reason, option B is False.
The question states that you were able to connect the external Hard drive and drag files onto it, though unsuccessfully. This tells us that the USB port is working as intended, if it were not working, it would not display the Hard drive onto the computer and we would not be able to drag files to it. Therefore, option C is false
Insufficient Hard drive storage space is a common issue in not being able to transfer files between hard drives. However, if this were the case, the user would be shown a message displaying the error. The message may look like:
"Insufficient space on the disk.""The Disk is full.""Not enough memory to complete this action"The exact wording may vary depending on the operating system in use. Since the question states that the files simply "bounces back" without an error message displaying, we can infer that option A is false.

You have n warehouses and n shops. At each warehouse, a truck is loaded with enough goods to supply one shop. There are m roads, each going from a warehouse to a shop, and driving along the ith road takes d i hours, where d i is an integer. Design a polynomial time algorithm to send the trucks to the shops, minimising the time until all shops are supplied.
Following are the steps of the polynomial-time algorithm:
Split the routes according to their categorizationAssuming that mid = di of the middle road, low = road with the least di, and high = road with the highest di, we may do a binary search on the sorted list.All shops must be approachable only using these roads for every road, from low to mid.Check if all shops can be reached from[tex]\bold{ low \ to\ mid+1}[/tex] using only these roads.There is a solution if every shop can be reached by road only up to [tex]\bold{mid+1}[/tex], but not up to mid.You can [tex]\bold{set \ low = mid+1}[/tex] if all businesses aren't accessible using both [tex]\bold{mid\ and\ mid+1}[/tex] roads.If every shop could be reached using both mid and mid+1, then set high to mid-1.With these layouts of businesses and roads, no response can be given because [tex]\bold{ low > high}[/tex]You can do this by [tex]\bold{set\ mid = \frac{(low + high)}{2}}[/tex]The new low, mid, and high numbers are used in step (a).In a minimum amount of time, this algorithm will determine the best strategy to supply all shops.

How to prepare and draw a corresponding flowchart to compute the sum and product of all prime numbers between 1 and 50
Answer:
Create boxes with the following content
Initialize sum to 0, product to 1 and number to 1Check if number is a prime. If yes, update sum += number and product *= numberIncrease number by 1If number is <= 50, go back to "check" block.The check block has a diamond shape.
At the "yes" branch of the check block, you can create separate blocks for updating the sum and the product.
Connect the blocks using arrows.
Indicate the start and the end of the flow using the appropriate symbols.
The block to check if a number is a prime you could further decompose into the steps needed to do such a check.
