Answer:
Following are the correct code to this question:
phrase = "abcdefgh"#defining a variable phrase that holds a string value
print(phrase[3:6])#use print method for slicing and print its value
Output:
def
Explanation:
In the above code, a variable "phrase" is defined that holds a string value, and use a print method, inside the method, the variable is used as a list and use slicing.
It is a characteristic that enables you to access the series parts like strings, tuples, and lists. It also uses for modifying or removing objects in series, in the above slicing it starts from 3 and ends when it equal to the 6th letter, that's why it will print "def".

Explanation:
A string is represented as an array of characters. If you need to store an array of 5 strings with the maximum length of a string is 100, how would you declare it
Answer:
char str[5][100]
Explanation:
See attachment for options:
From the options, we can see that the programming language is C language.
The syntax to store an array of m strings with a maximum of n elements in C is:
char array-name[m][n]
In this case:
[tex]m = 5[/tex] --- Number of strings in the array
[tex]n = 100[/tex] --- Maximum character in each string
Assume the array name is str, the syntax can be expressed as:
char str[5][100]
An alternative design for a canary mechanism place the NULL value just below the return address. What is the rationale for this design decision
Answer:
This is to prevent attacks using the strcpy() and other methods that would return while copying a null character.
Explanation:
Canary is a mechanism used to monitor and prevent buffer overflow. The alternative canary design that places a null value just before the return address is called the terminator canary.
Though the mechanism prevents string attacks, the drawback of the technique is that the value of the canary is known which makes it easy for attackers to overwrite the canary.

Write a code in C++ that can save 100 random numbers in an array that are between 500 and 1000. You have to find the average of the 100 random numbers. To find the average of the numbers, you have to use a functions. You are not allowed to use return, cin or cout statements in the functions.
Hint : you have to use function call by reference.
Answer:
#include <iostream>
#include <random>
//here we are passing our array and a int by ref
//to our function called calculateAverage
//void is infront because we are not returning anything back
void calculateAverage(int (&ar)[100], int &average){
int sum = 0;
for(int i = 0;i < 100; i++){
//adding sum
sum += ar[i];
}
//std:: cout << "\naverage \t\t" << average;
//calculating average here
average += sum/100;
}
int main() {
int value = 0;
int average = 0;//need this to calculate the average
int ar[100];
//assign random numbers from 500 to 1000
//to our array thats called ar
for(int i = 0; i < 100; i++){
value = rand() % 500 + 500;
ar[i] = value;
}
calculateAverage(ar,average);
// std:: cout << "\naverage should be \t" << average;
}
Explanation:
not sure how else this would work without having to pass another variable into the function but I hope this helps!
I commented out the couts because you cant use them according to ur prof but I encourage you to cout to make sure it does indeed calculate the average!
Write a print statement that displays a random integer between 5 and 5000. Assume the random library is imported.
Answer:
Explanation:
The following code is written in Java. It is a very simple three line statement (assuming that the random library was imported) that chooses a random integer value between 5 and 5000 and prints it to the screen using the println statement.
Random rand = new Random();
int randomNum = rand.nextInt((5000 - 5) + 1) + 5;
System.out.println(randomNum);
The random number generator is initialized and given a value between 5 and 5000. Since random number Generator will generate a number between 0 and the given value then subtracting 5 from the initial generated number makes sure that it is not more than 5000 and then adding 1 and 5 after wards makes sure that it is more than 5 always.

Have you ever played the game Mad Libs? Basically, the goal is to build a story using a template and have other people fill in the blanks. They make for pretty funny stories because the people filling in the blanks don’t know what the story is about!
For this activity, you will be creating your own Mad Libs game. It’s similar to the way you created the Introduction paragraph in the unit.
Start by typing out your Mad Libs fill-in-the-blank story in a word processing document. Make it as creative as possible! Identify whether your blanks should be filled by nouns, verbs, adjectives, or adverbs. Your story should include at least 10 blanks.
Next, transform your story into one big Python print statement in REPL.it, using variables in place of the blanks.
Finally, create the variables you need for your template by putting them at the top of your program. You should use input statements to make the game interactive.
Test out your program thoroughly, fixing any syntax errors or bugs that arise. Once you are happy with it, take a screenshot of your code actually being run.
Copy and paste your code into the same document where you wrote your fill-in-the-blank story, so that you have the regular fill-in-the-blank version and the code version.
Have a friend or family member try your Mad Lib (the typed or the coded version). Record yourself reading the result.

Provide an example of an IT project from your readings, experience, and/or other sources and discuss some of the challenges faced in its implementation. Suggest ways to overcome such challenges to achieve successful outcomes.
Answer:
kindly check the explanation.
Explanation:
Getting any project to be a successful one is not an easy task at all as many projects failed even before it nears completion stage. The Project Management Institute[PMI] states that only 69% [mean percentage] are able to complete and meet the original goals for and business intent of the project.
The reasons behind this failed IT projects are numerous, few of them are given below:
=> When estimates for the IT project is inaccurate. Th inaccuracy do cause IT projects to not meet the target.
=> When the available resources are not enough and there is poor project management it causes the IT projects to fail.
=> When team members are not diligent. The procrastination of team members do lead to failed projects.
The ways that such problems can be overcome in order to to achieve successful outcomes is given below;
=> Someone should be held accountable. That is there should be a seasoned and qualify project manager to supervise the project and can be hold accountable for how things turns how to be.
=> The scope of the project should be flexible so that when things changes the plan can also change.
=> Making sure that all the estimates are accurate.
Ann Marie would like to test her hypothesis. To do that, she needs to show groups of data that are similar in some way. Which data-mining techniques should she use?
Answer:
Clustering Analysis
Explanation:
Clustering analysis or otherwise called cluster analysis is a task composed of grouping sets of objects in a way that objects in the same group tend to be more similar to each other than to objects in some other groups. Like the question said, Ann would love to show groups of data that are similar in some way. This makes Clustering analysis the perfect choice of pick, because of the similarity that's needed. A result of cluster analysis is capable of being used in the creation of something like customer profiling.

Write a function named average_value_in_file that accepts a file name as a parameter and reads that file, assumed to be full of numbers, and returns the average (mean) of the numbers in that file. The parameter, filename, gives the name of a file that contains a list of numbers, one per line. You may assume that the file exists and follows the proper format. For example, if a file named input.txt contains the following numbers
def average_value_in_file(filename):
f = open(filename)
total = 0
count = 0
for x in f.read().splitlines():
total += int(x)
count += 1
return total/count
print(average_value_in_file("input.txt"))
I used an input file that looks like this:
1
1
1

What is the output?
answer = 0
for numA in [2,4]:
for numB in [3, 5]:
answer = answer + numA + numB
print (answer)
Output:
Answer:
The output is 28
Explanation:
Required
Determine the output of the code segment
The first line initializes "answer" to 0
The next two lines iterate through lists [2,4] and [3,5
Each of these lists have two elements; So, the number of iterations is 2 * 2 i.e. 4.
In the first iteration
numA = 2, numB = 3, answer = 0
So:
[tex]answer = answer + numA + numB= 0 + 2 + 3 = 5[/tex]
In the second iteration
numA = 2, numB = 5, answer = 5
So:
[tex]answer = answer + numA + numB= 5 + 2 + 5 = 12[/tex]
In the third iteration
numA = 4, numB = 3, answer = 12
So:
[tex]answer = answer + numA + numB= 12 + 4 + 3 = 19[/tex]
In the fourth iteration
numA = 4, numB = 5, answer = 19
So:
[tex]answer = answer + numA + numB= 19 + 4 + 5 = 28[/tex]
Lastly, the value of "answer" is printed
Hence, the output is 28
Answer: 28

Brian gathers data from his classmates about the computers they own such as the type of operating system, the amount of memory, and the year the computer was purchased. Who/what are the individuals in this data set
Incomplete question. The Options read;
A. The year purchased
B. Brian's classmates
C. The amount of memory
D. The type of operating system
Answer:
B. Brian's classmates
Explanation:
Remember, the question is concerned about "the individuals" in the data set, so the year they purchased their computer, neither is the amount of memory of the computer and the type of operating system can be classified as individuals in the data set.
Hence, we can correctly say, only Brian's classmates are the individuals in this data set.

Write a class named Octagon whose objects represent regular octagons (eight-sided polygons). Your class should implement the Shape interface defined, including methods for its area and perimeter. An Octagon object is defined by its side length
Answer:
Answered below
Explanation:
//Code is written using Kotlin programming language.
interface Shape{
var length : Double
fun area(length: Double)
fun perimeter (length: Double)
}
Class Octagon(var length: Double) : Shape{
val side: Int = 8
override var length: Double = length
override fun perimeter ( length: Double):Double{
return side * length
}
override fun area(length: Double): Double {
return 2*side**2(1+\Math.sqrt(2)
}
}
//Test class
Class Main{
fun main(){
val octagon = Octagon(2.5)
val perimeter = octagon.perimeter()
val area = octagon.area
print(perimeter, area)
}
}
Write a program that will read a line of text as input and then display the line with the first word moved to the end of the line
Answer:
The program in Python is as follows:
text_input = input("Enter text: ")
first_word = text_input.split(" ")
new_text = text_input.replace(first_word[0], "")
new_text = new_text + " "+ first_word[0]
print("New Text: " + new_text)
Explanation:
This line gets a line of text from the user
text_input = input("Enter text: ")
This line splits the text into list
first_word = text_input.split(" ")
This line deletes the first word of the string
new_text = text_input.replace(first_word[0], "")
This line appends the first word to the end of the string
new_text = new_text + " "+ first_word[0]
This line prints the new text
print("New Text: " + new_text)
Write a program in python whose input is a string which contains a character and a phrase, and whose output indicates the number of times the character appears in the phrase.
Answer:
Explanation:
The following is written in Python as requested and performs this task with a function called count_appearances. It first makes the character and the phrase into all lowercase and then loops through each word in the phrase and compares it to the character. If they are the same it adds 1 to the counter. Once the loop is over it returns the counter which is the number of times that the character appeared in the phrase.
def count_appearances(character, phrase):
count = 0
character = character.lower()
phrase = phrase.lower()
for x in phrase.split():
if x == character:
count += 1
return count
how would i change this:
" try:
userChoice = input("Would you like to Add or Multipy?(A/M): ")
except:
print("Please enter 'A' or 'M'") "
so it only allows me to put "A" or "M" so that it runs the except part
You wouldnt use a try and except statement. Use a loop.
