Explanation:
When adding delegates to his mailbox, which role should Joel use if he would like the user to be able to read and create items in a particular folder?
- editor
- publishing editor
- author
- manager
Answer:
publishing editor
Explanation:
In this scenario, the role that he should choose for the delegates would be publishing editor. This role will allow them to create, read, modify, and delete all items within a given folder, and create subfolders. The other options listed either do not give access to create/modify existing files or simply only give all these rights with files that the user creates but not files that already existed in the folder. Therefore, this would be the best role for what Joel wants to accomplish.
10.11 LAB: Pet information (derived classes) The base class Pet has private data members petName, and petAge. The derived class Dog extends the Pet class and includes a private data member for dogBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Dog pet, use PrintInfo() to print information, and add a statement to print the dog's breed using the GetBreed() function.
Answer:
Answered below.
Explanation:
//Program in Java
Class Test{
public static void main (String[] args){
//create a pet object
Pet pet = new Pet();
//call pet object's printInfo method
pet.printInfo();
//create a new Dog object
Dog dog = new Dog();
//dog can access the printInfo method of the Pet class because it derives from it
dog.printInfo();
//dog can also call it's private method.
dog.getBreed();

802.3 is a standard specification for Ethernet, a method of packet-based physical communication in a local area network (LAN), which is maintained by the Institute of Electrical and Electronics Engineers (IEEE). In general, 802.3 specifies the physical media and the working characteristics of Ethernet.
Suppose we define a WaitlistEntry as follows:
typedef struct{
int iPriority; /* Priority of the student to be enrolled */
int iStudentID; /* ID of the student */
}
WaitlistEntry;
Below are different implements of a function to create a WaitlistEntry from given iPriority and iStudentID data. Some of these implementations are flawed. Identify them and describe what is wrong with them briefly:
WaitlistEntry createWL( int iPriority, int iStudentlD )
WaitlistEntry w,
w.iPriority iPriority;
w.iStudentlD iStudentlD;
return w;
a. correct
b. incorrect, leaks memory
c. incorrect, syntax error
d. incorrect, data will be overwritten by next function call
Answer:
You have syntax errors, but I don't know if it happened when you posted this question, nevertheless
Explanation:
Correct code:
WaitlistEntry createWL( int iPriority, int iStudentID ) { // Opening Brace
WaitlistEntry w; // Should be ; not ,
w.iPriority = iPriority; // Assign Missing
w.iStudentID = iStudentID; // Assign Missing
return w;
} // Closing Brace
// Also note: iStudentID this actually has an 'l' which is LD. Not ID, this is why I assume these errors happened when posting the question.
As of Spring 2020, in otder to get into the CS major, you must have a 3.0 GPA or better in cs120, cs210, and cs245. In this problem, you should write one function named get_gpa, which will calculate this GPA. This function should have one parameter, which will be a dictionary of grades in computer science courses. You can assume that the dictionary will always have the keys 'cs120', 'cs210', and 'cs245', but it also might contain some names of other courses too. The values associated with each key will be a float representeing the GPA-style grade for that class. For instance, the parameter dictionary might look like: {'cs120':4.0 'cs245':3.0, 'cs210':2.0}. Some examples:
get_gpa({'cs110': 4.0, 'cs245':3.0, 'cs335':4.0, 'cs120':3.0, 'cs210':3.0}) should return 3.0.
get_gpa({'cs110': 4.0, 'cs120':3.0, 'cs245':2.0, 'cs210':1.0}) should return 2.0.
get_gpa({'cs245':4.0, 'cs120':3.0, 'cs245':2.0}) should return 3.0.
Make sure to include only the one function in your file.
Answer:
The function is as follows:
def get_gpa(mydict):
gpa = 0
kount = 0
for course_code, gp in mydict.items():
if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':
gpa += float(gp)
kount+=1
return (gpa/kount)
Explanation:
This defines the function
def get_gpa(mydict):
This initializes gpa to 0
gpa = 0
This initializes kount to 0
kount = 0
This iterates through the courses
for course_code, gp in mydict.items():
If course code is cs120 or cs210 or cs245
if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':
The gpa is added
gpa += float(gp)
And the number of courses is increased by 1
kount+=1
This returns the gpa
return (gpa/kount)

How is an interpreter different from a compiler?
An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.
An interpreter translates all code at once so that it is ready to be executed at any time, while a compiler translates and executes code line by line.
An interpreter translates programming code into binary language, while a compiler does not.
An interpreter translates binary language into programming language, while a compiler translates programming language into binary language.
Answer:
An interpreter is quite different from a complier due to the following statement below:
O. An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.
Explanation:
For an interpreter, it works in translating and execution of the codes line after another line. In a situation where there is a mistake in the code, the next line would not be able to be executed, but rather display error message. On the other hand, compiler translate all codes at once and execute them as a single work.
During its translation of the codes in compiler, should there be any error, it would not be able to execute despite the fact that, the error might be in the last line of the code.

HLOOKUP is used for Horizontal Data look ups while VLOOKUP is for Vertical Data look ups
Select one:
True
False
Answer:
True
Explanation:
Both HLOOKUP and VLOOKUP are excel functions used for searching through tables for a specified lookup value to either get an exact or approximate match. The VLOOK and HLOOKUP functions have identical syntax which only differs with the HLOOKUP requiring the row index number to search through the rows while, VLOOKUP requires the column index number to search through the columns. Other than this difference, the other syntax values are the same.
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])

You need to write a menu driven program. The program allows a user to enter five numbers and then asks the user to select a choice from a menu. The menu should offer the following four options – 1. Display the smallest number entered 2. Display the largest number entered 3. Display the sum of the five numbers entered 4. Display the average of the five numbers entered
Answer:
In Python:
nums = []
for i in range(5):
num = int(input("Num: "))
nums.append(num)
print("1 - Smallest")
print("2 - Largest")
print("3 - Sum")
print("4 - Average")
menu = int(input("Select menu: "))
if menu == 1:
print("Smallest: ",min(nums))
elif menu == 2:
print("Largest: ",max(nums))
elif menu == 3:
isum = 0
for i in range(5):
isum+=nums[i]
print("Sum: ",isum)
elif menu == 4:
isum = 0
for i in range(5):
isum+=nums[i]
print("Average: ",isum/5)
else:
print("Invalid Menu Selected")
Explanation:
This program uses a list to get inputs for the 5 numbers
Here, the list is initialized
nums = []
This iterates from 1 to 5
for i in range(5):
This gets input for the 5 numbers
num = int(input("Num: "))
This appends each number to the list
nums.append(num)
The next 4 lines represents the menu
print("1 - Smallest")
print("2 - Largest")
print("3 - Sum")
print("4 - Average")
This prompts the user for menu
menu = int(input("Select menu: "))
If menu is 1, print the smallest
if menu == 1:
print("Smallest: ",min(nums))
If menu is 2, print the largest
elif menu == 2:
print("Largest: ",max(nums))
If menu is 3, calculate and print the sum of all inputs
elif menu == 3:
isum = 0
for i in range(5):
isum+=nums[i]
print("Sum: ",isum)
If menu is 4, calculate and print the average of all inputs
elif menu == 4:
isum = 0
for i in range(5):
isum+=nums[i]
print("Average: ",isum/5)
If menu is not 1 to 4, then print invalid menu
else:
print("Invalid Menu Selected")
The Painting Company has determined that for every 112 square feet of wall space:
One gallon of paint at $9.53 per gallon is required if total square feet is 2000 or less. If square footage is greater than 2000, paint is $10.50 per gallon.
8 hours of labor at $35 per hour is required.
A hazardous material disposal fee of 7.5% of the total paint cost is required.
Create a function called paintJobCost which allows the user to provide the total number of square feet for the paint job and produces an itemized list of charges that includes:
Number of gallons of paint required.
Total Cost of the Paint (Paint Cost x Gallons Required)
Hours of labor required to paint (8 hrs per 112 sq ft)
Total Cost of the Labor.
The hazardous material fee.
The total cost of the paint job. (Paint Cost + Labor Cost + Hazardous Material fee)

Consider the following incomplete method. Method findNext is intended to return the index of the first occurrence of the value val beyond the position start in array arr. I returns index of first occurrence of val in arr /! after position start; // returns arr.length if val is not found public int findNext (int[] arr, int val, int start) int pos = start + 1; while condition '/ ) pos++ return pos; For example, consider the following code segment. int [ ] arr {11, 22, 100, 33, 100, 11, 44, 100); System.out.println(findNext (arr, 100, 2)) The execution of the code segment should result in the value 4 being printed Which of the following expressions could be used to replace /* condition */ so that findNext will work as intended?
(A) (posarr.length) &&(arr [pos]- val)
(B) (arr [pos] != val) && (pos < arr. Îength)
(C) (pos
(D) (arr [pos} == val) && (pos < arr. length)
(E) (pos
Answer:
B)
Explanation:
The while loop runs as long as two conditions are satisfied, as indicated by the && logical operator.
The first condition- arr[pos] != val
checks to see if the value in the array index, pos, is equal to the given value and while it is not equal to it, the second condition is checked.
The second condition(pos < are.length), checks to see if the index(pos) is less than the length of the array. If both conditions are true, the program execution enters the while loop.
The while loop is only terminated once arr[pos] == Val or pos == arr.length.

Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 12-character telephone number in the format: XXX-XXX-XXXX. Acceptable characters (X's) are A-Z and a-z. Your program should check for: The length of the phone number is correct. The dashes are included and are in the correct positions. There are no characters in the illegal characters in the string. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. If the input string is not entirely correct then you should print an error message. For example, if the user enters 555-GET-FOOD the program should display 555-438-3663. If the user enters 123-456-7890, the program should display 123-456-7890. Rules: You must have one function (in addition to main()) that converts an alphabetic character to a digit. Or you can have one function that coverts all characters to digits. You can make your own function or use a built-in function if one exists.
Answer:
The program in Python is as follows:
def convertt(phone):
splitnum = phone.split ('-')
valid = True

numphone = ""
if len(phone) != 12:
err = "Invalid Length"
valid = False

This is absolutely true. A shining example of this is with smartphones. Before Apple introduced the world to the iPhone, most smartphones had actual keyboards, zero touchscreen capabilities, could barely browse the internet, and had very small displays. After the iPhone was released in 2007, companies immediately scrambled to come out with phones that looked uncannily similar to Apple's. Why? Because Apple's phone was designed well. It's pretty amazing how immediate the shift was. In fact, I recomend you look up "Smartphones before and after iPhone" online. It's pretty cool.
