What is the main advantage of using a WYSIWYG (“what you see is what you get”) editor when constructing a website?
Only one programming language is required.
Websites may have more professional construction.
Knowledge of HTML is not required.
Website templates are not necessary.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer among the given options to this question is:
Knowledge of HTML is not required.
Because when you are constructing a website using WYSIWYG (“what you see is what you get”) editor, then you don't need the knowledge of HTML. Because, when you use WYSIWYG editor to insert button, table, images, text, paragraph, etc. It will automatically insert HTML code behind the page. For example, you can insert a form and a submit button using drag and drop with the help of WYSIWYG (“what you see is what you get”) editor, for this purpose, you don't need exact knowledge of HTML. WYSIWYG (“what you see is what you get”) automatically inserts the HTML for the form and button on a website page.
While other options are not correct because:
Using the WYSIWYG (“what you see is what you get”) editor, you can use different programming languages in your website, such as VB.net, Asp.Net, C#, Javascript, Bootstrap, etc. It is not necessarily that you may have more professional construction and in WYSIWYG (“what you see is what you get”) website templates are mostly used and modified using WYSIWYG editor.
Answer:
(C):Knowledge of HTML is not required.

resolution.
magnification.
orientation.
colors.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The given options to this question are:
resolution. magnification. orientation. colors.The correct option to this question is 1. i.e.
Resolution.
The resolution of an image determines how many pixels per inch an image contains. Image having a higher resolution takes long page load times for a page and lower resolution takes less page load time. So, to prevent long page load times for pages containing images, it is best to use compressed file formation as well as appropriate image dimension and resolution.
While other options are not correct because:
Magnification, orientation, and color does not affect the page load time. Page load time for images only affected by the dimension and resolution of the images.

What are stored procedures? What kind of attack do stored procedures protect from? Identify two reasons why stored procedures are a good mitigation against the specific attack. g
Answer:
Stored procedures or procedures are subroutines or subprograms in SQL written by the user to accomplish a certain task. it helps to mitigate SQL injection by using markers as placeholders for data input and it streams the query statement and data separately in the database.
Explanation:
The stored procedure used in SQL is a user-defined function. Unlike built-in functions like pi(), they must be called to use them.
SQL injection in query statements is written by hackers to bypass conditions, especially when trying to gain access to other user accounts. Stored procedures use markers or placeholders to prevent this.

It returns a status value of the queried table.
Explanation:
A stored procedure is a subroutine used in SQL servers to perform a task on a table in a database or the database itself. The syntax for creating a stored procedure is;
CREATE PROCEDURE procedure_name
And then, other statements can be written to be executed when the procedure is called.

If you wanted to make the system sequentially consistent, what are the key constrains you need to impose
Answer:
The call of instructions and data must be sequential, there can be no reordering of instructions but to allow reordering, a fence must be created.
Explanation:
Sequential consistent memory model is able to use instructions when or before processing is done and after processing, so long as the instruction order is sequential.
This is similar to uploading a video on you-tube, the site immediately creates a page for the video even before the video is fully uploaded. Sent tweeter messages are seen by different people at different times, but the messages appear to be arranged sequentially.
Suppose that you have the following declaration:
stack Type stack(50); double num; and the input is
25 64-3 6.25 36-4.5 86 14 -129
Write a C++ code that processes this input as follows: If the number is non-negative, it pushes the square root of the number onto the stack; otherwise it pushes the square of the number onto the stack. After processing these numbers write a C++ code that outputs the elements of the stack.
Answer:
Explanation:
The code is written in C++:
#include <iostream>
#include <stack>
#include <math.h>
#include <iomanip>
using namespace std;
/*
* Supporting method to print contents of a stack.
*/
void print(stack<double> &s)
{
if(s.empty())
{
cout << endl;
return;
}
double x= s.top();
s.pop();
print(s);
s.push(x);
cout << x << " ";
}
int main(){
// Declaration of the stack variable
stack<double> stack;
//rray with input values
double inputs[] = {25,64,-3,6.25,36,-4.5,86,14,-12,9};
/*
* For each element in the input, if it is positive push the square root into stack
* otherwise push the square into the stack
*/
for(int i=0;i<10;i++){
if(inputs[i]>=0){
stack.push(sqrt(inputs[i]));
}else{
stack.push(pow(inputs[i],2));
}
}
//Print thye content of the stack
print(stack);
}

Write a loop to print all elements in hourly_temperature. Separate elements with a -> surrounded by spaces. Sample output for the given program: (must be in python)
90 -> 92 -> 94 -> 95
Note: There is a space after 95.
------------------------------------------------------------------------------------------------------------------------
hourly_temperature = [90, 92, 94, 95]
for temp in hourly_temperature:
for index,temp in enumerate(str(temp)):
if index != len(temp)-1:
print(temp,'->',end=' ')
else:
print(temp, end='')
print('') # print newline
------------------------------------------------------------------------------------------------------------------------
My expected out is:
90 -> 92 -> 94 -> 95
I keep getting:
90 -> 92 -> 94 -> 95 ->
NOTE: I can't edit the last line "print('') #print newline"
Answer:
Following are the code to this question:
hourly_temperature = [90, 92, 94, 95]#defining a list that holds values
c= 0#defining a variable c
for temp in hourly_temperature:#defining a for loop to count list values
c+= 1#defining c variable to increment the value of c
for index,temp1 in enumerate(str(temp)):#defining for loop for spacing the list value
if index == len(str(temp))-1 and c!= len(hourly_temperature):#defining if block that checks the length of list
print(temp1,'->',end=' ')#print value
elif c == len(hourly_temperature) and index == len(str(temp)) - 1:#defining elif block that checks the length of list
print(temp1, end=' ')#print value
else:#defining else block
print(temp1, end='')#print value
Output:
90 -> 92 -> 94 -> 95
Explanation:
In the above-given code, a list "hourly_temperature" is declared, in which an integer variable c is declared, that holds an integer value that is equal to 0, and two for loop is declared, and in the first loop is used for count list value, and inside the for loop is uses enumerate method to assigns an index for each item and use the conditional statement to check each list value and provide space in each element value.

Write a second ConvertToInches() with two double parameters, numFeet and numInches, that returns the total number of inches.
Answer:
Answered in C++
double ConvertToInches(double numFeet, double numInches){
return numFeet*12 + numInches;
}
Explanation:
A foot is equivalent to 12 inches. So, the function converts feet to inches by multiplying the number of feet by 12.
The question is answered in C++
This line defines the method with two parameters
double ConvertToInches(double numFeet, double numInches){
This line converts the input parameters to inches and returns the number of inches
return numFeet*12 + numInches;
}
To convert 9 feet and 12 inches to inches, the main method of the program can be:
int main(){
cout<<ConvertToInches(9,12);
return 0;
}
This above will return 120 because: 9 * 12 + 12 = 120 inches

what is one issue when organizing around hierarchical functions
Answer:
The one issue that arises when organizing around hierarchical functions is the dilution of information caused by the absence of direct communication with the overall boss.
Explanation:
This problem is more pronounced when it takes an organization a longer time before initiating hierarchical functions. Employees who have grown used to communicating directly with their bosses will now be distanced from them because direct reports to the overall bosses are no longer permitted. Instead, each functional head is expected to coordinate their group information, have it thoroughly filtered before allowing the overall boss to access it. One advantage is that functional hierarchies eliminate information overflow. Unfortunately, some bosses do not feel comfortable, at first, when their organizations commence hierarchical organization of business functions.
