Explanation:
I run an online e-commerce store and lately its been very difficult keeping track of customer detail, incoming orders, keyword generation etc. One solution that I thought about would be an application that controls all of that for me. In order to accomplish this I would first need to design and create a GUI that contains all of the necessary buttons and displays for the information. Then I would need to code a webscraper using Python to grab all of the data from e-commerce store as soon as it becomes available, organize it, and display it within the GUI.

Explanation:
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.

Iconic designs are inspirational and are often copied.
True
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. Here's an image example: https://www.redmondpie.com/image-showing-phones-before-and-after-iphone-x-revisits-how-android-market-still-tends-to-copy-iphone/

Please read the following problem carefully. You will then logon on to https://www.draw.io/to create a professional diagram. You will put all titles, labels, and save your work using the information below. Please follow the directions:
Destini would like to get a better understanding of her grades in all of her college courses before Spring Break. Instead of using a calculator and paper to calculate her grade, she decided to design a program. She will design a program that will ask her to enter her course name and the number of grades in her grade book. The program will then Read the number of Grades based on what was entered by her, Add up all the Grades, Calculate the Average, and Display Course Name and the Average to Screen. It is important to consider that the number of grades will be different for each course. Using Repetition Control, please design this program.
1. Please Create Flowchart using Draw.10 and Simple Flowchart symbols only (Draw.IO)
2. Pseudocode.
Your unique Flowchart must have the following (See Example Here):
A. Name, Date, and class Name [Top Left of Flowchart)
B. A Title of the Flowchart in Bold [Centered at the top of your flowchart)
C. A Brief Summary of your Flowchart (2 to 3 short sentences describing your flowchart) [Left of Flowchart]
Answer:
The pseudocode is as follows:
Input coursename, numgrades
count = 1; totalgrades = 0
while count <= numgrades:
input grade
totalgrade+=grade
count++
average = totalgrade/count
print(coursename)
print(average)
Explanation:
The solution is as follows:
(1) See attachment for flowchart
(2) See answer section for pseudocode
Explanation
Input coursename and number of grades
Input coursename, numgrades
Initialize count of grades input by the user to 1 and the sum of all grades to 0
count = 1; totalgrades = 0
This loop is repeated while count of grades input by the user is less than or equal to the numgrades
while count <= numgrades:
Input grade
input grade
Add grades
totalgrade+=grade
Increase count by 1
count++
End of loop
Calculate average
average = totalgrade/count
Print coursename
print(coursename)
Print average
print(average)
C. Summary of the flowchart
The flowchart gets coursename and the number of grades from the user. Then it gets the score of each grade, add them up t calculate the average of grades.
Lastly, the course name and the average grades is printed

A sql-6-5.sql file has been opened for you. Write each of the following tasks as a SQL statement in a new line (remember that you can source the file to compare the output reference): Use the e_store database Select the total stock of all products in the products table. Alias the column name as total_stock. The resulting table should look like this:
Answer:
The query is as follows:
select sum(stock) as total_stock from products
Explanation:
Required
Return total stock using the alias total_stock from the product table.
The explanation of the query is as follows:
select ----> This implies that data is to be selected from the table
sum(stock) ----> This adds up entries in stock column
as total_stock ---> This represents the alias used for sum(stock)column where
from products ----> The table being queried
Take for instance, the content of the table is:
SN Product Stock
1 Apple 5
2 Orange 3
3 Banana 8
The query will return the following table:
total_stock
16
You will use conditionals, loops, and functions to implement a trigonometric functions calculator.
THE PROBLEM
You must complete the provided Python program to calculate three trigonometric functions based on the user's input. The user can select the following trigonometric functions: 1. Sine, 2. Cosine, and 3. Tangent. The user will input option 4 to exit the program. If the user inputs a number different than 1, 2, 3, or 4, your program must print into the display the following message: Invalid option. Your program will keep asking the user for an option until the user choice is 4 (exit).
Trigonometric functions:
Sine: to calculate the sine of an angle (in radians), you must use the following Maclaurin series (Wikipedia):
sin(x) = ∑[infinity]n=0(−1)nx2n+1(2n+1)!∑n=0[infinity](−1)nx2n+1(2n+1)!
Where x is the value of the angle in radians.
Cosine: to calculate the cosine of an angle (in radians), you must use the following Maclaurin series (Wikipedia):
cos(x) = ∑[infinity]n=0(−1)nx2n(2n)!∑n=0[infinity](−1)nx2n(2n)!
Tangent: For the value of an angle different than 90 or 270 (in degrees), the tangent is:
tan(x) = sin(x)cos(x)sin(x)cos(x)
Where x is the value of the angle in radians.
User-defined Functions:
You must write the definition of the following functions:
factorial: this function receives as a parameter an integer value and returns the factorial of the received value. For a parameter equal to 5, the function returns 120 (5 * 4 * 3 * 2 * 1).
sin: this function receives two parameters (a float representing the value of the angle in radians and an integer value representing the number of terms of the Maclaurin series to be calculated). The function returns the value of the sine of the first parameter calculated with the first n terms of the Maclaurin series for the sine (where n is the second parameter received by the function).
cos: this function receives two parameters (a float representing the value of the angle in radians and an integer value representing the number of terms of the Maclaurin series to be calculated). The function returns the value of the cosine of the first parameter calculated with the first n terms of the Maclaurin series for the cosine (where n is the second parameter received by the function).
degTorad (provided): this function receives as a parameter an integer value representing an angle in degrees and returns the value of the received angle in radians.
printMenu (provided): this function does not receive parameters and does not return a value. The function prints the to STDOUT (display) the menu to be used by the user.
Main program:
The main program is provided in the template file. Please use the comments in the template file to complete your solution.
Input:
Your program takes as initial input one integer value representing the menu option. If the initial input value is a trigonometric function (1, 2, or 3), the program will request two additional inputs (an integer value representing an angle in degrees and the number of terms used in the Maclaurin series). The input statements are provided in the template file.
Output:
The print statements are provided in the template file (do not modify the output messages).
Note:
You can safely assume that the input will always be valid.

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.
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])
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
count = 0
err = ""
numphone = ""
if len(phone) != 12:
err = "Invalid Length"
valid = False
elif phone[3] != '-' or phone[7] != '-':
err = "Invalid dash [-] location"
valid = False
while valid== True and count < 3:
for ch in splitnum[count]:
if ch.isdigit():
numphone += ch
elif ch.upper()in 'ABC':
numphone += '2'
elif ch.upper()in 'DEF':
numphone += '3'
elif ch.upper()in 'GHI':
numphone += '4'
elif ch.upper() in 'JKL':
numphone += '5'
elif ch.upper()in 'MNO':
numphone += '6'
elif ch.upper()in 'PQRS':
numphone += '7'
elif ch.upper()in 'TUV':
numphone += '8'
elif ch.upper()in 'WXYZ':
numphone += '9'
else:
valid = False
err = "Illegal character in phone number"
if count!=2:
numphone += '-'
count += 1
if valid == False:
print (err)
else:
print ("Phone Number", numphone)
phone = input("Phone number: ")
convertt(phone)

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)

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.
