Consider a Dog class and a Mammal class. Which is true? Group of answer choices The Dog class is abstract The Mammal class is concrete Both classes are concrete The Mammal class is abstract
Mammals include mammals having hair, udders used to suckle infants having milk, a stomach, four bones in the eardrum, and a jaw bone built up of a single set of bones which clarifies with the skull uniquely.
This will be an abstract class with some functions that aren't declared, and their functions can be declared in the given class, which would be a dog class. The statement that a mammalian is an abstract class is true because the dog class is a mammal.Therefore, the answer is the last choice "Mammal is an abstract class".

An algorithm whose worst-case time complexity is bounded above by a polynomial function of its size is called a(n)
Answer:
polynomial-bounded algorithms
Explanation:
There are two algorithm complexities and they are time and space complexities. They can be denoted with the big-O notation. The big-o notation for a time and space complexity gets the worst-case time and space respectively.
The time complexity gets the measure of the execution time of an algorithm. When the time function is a polynomial ( k^n + k^n-1 ...) then the algorithm is said to be a polynomial-bounded algorithm.

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

Write a program that calculates the average of N integers. The program should prompt the
user to enter the value for N and then afterward must enter all N numbers. If the user enters a
negative value for N, then an exception should be thrown (and caught) with the message “ N
must be positive.” If there is any exception as the user is entering the N numbers, an error
message should be displayed, and the user prompted to enter the number again.
Answer:
def Average(num):
if num == 0:
return 0
val = 0
trueNum = num
for i in range(0, num):
try:
val += int(input("Enter value (%d out of %d): " % (i+1,num)))
except Exception as e:
print ("Error processing value. Non integer detected.")
try:
val += int(input("Enter value (%d out of %d): " % (i+1,num)))
except Exception as e:
print ("Error processing value. Non integer detected.")
print ("OMITTING value from average.")
trueNum -= 1
return val/trueNum
def main():
try:
num = int(input("Enter a value N for amount of items: "))
if num < 0:
raise(ValueError)
except ValueError:
print ("N must be positive integer.")
exit(1)
print("Average: ", Average(num))
exit(0)
if __name__ == "__main__":
main()
Explanation:
This program is written in Python to collect some integer value from the user as an upper bound of integers to be input for an average. Using this upper bound, the program checks to validate it is indeed an integer. If it not an integer, then the program alerts the user and terminates. If it is a user, the Average function is called to begin calculation. Inside the Average function, the user is prompted for an integer value repeatedly up until the upper bound. Using the sum of these values, the program calculates the average. If the user inputs a non integer value, the program will alert the user that the value must be an integer and ask again. If the user again inputs a non integer value, that iteration will be omitted from the final average. The program this prints the calculated average to the user.

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.

What is an information?An information refers to something that has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed.
The digital signals and other data use discrete signs or alogrithms to convey information, other phenomena and artifacts such as analog signals, poems, pictures, music or other sounds, and the electrical currents convey information in a more continuous form.
Information is not knowledge itself, but its interpretation is important. An Information can be in a raw form or in an structured form as data. The information available through a collection of data may be derived by analysis by expert analysts in their domain.

You need to implement a class that represents the state of a room or game section. The class will contain a room_id, a description, and possibly a choice1 and a choice 2. You will need to implement the __str__ override to output the state of the room. You should also implement a method called game_over. If the room does have a choice 1 and choice2 then the game is over and it should return True.
Answer:
class Home(object):
def __int__(self):
room1()
# room1 is the bedroom, you could either sleep or leave the room
def room1(self):
print("Room 1")
choices = ['sleep', 'leave']
for _ in iter(list, 0):
mychoice = input("What do you want to do here sleep/leave: ")
if mychoice == choice[0]:
print("You are sleeping")
elif mychoice == choice[1]:
self. room2()
else:
self. game_over()
# room2 is the living room for fun and recreation
def room2(self):
print("Room 2")
choices = ['watch a movie', 'dance', 'call a friend', 'leave']
mychoice = input("What do you want to do here: ")
for _ in iter(list,0):
if mychoice == choice[0]:
print("I love this movie")
elif mychoice == choice[1]:
print("You are a good dancer.")
elif mychoice == choice[2]:
self. room1()
else:
self. game_over()
# this method ends the program
def game_over(self):

Explanation:
The simple python object oriented program defines class with three methods room1, room2 and game_over which are all linked from the __init__ method from where the room1 is call first.
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.

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.
