When a new user visits your proprietary site, what is typically the first method of interaction with them
Answer:
Log file entry notifying you of new user activity
Explanation:
Log files are records of the timeline of activities in a computer system. These files contain information about new users of a site as well as the activities they performed on the site.
The internet protocol address of the visitor, the time of visit, as well as the features clicked on, or accessed by him, example, videos or images are all registered in the log file. The owner of the site can use the information sourced from the log files to perform site analytics.
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!
What symbol should you look for to determine who owns the intellectual property of a website?
Answer:
the logo of the company or corporation
Explanation:
Usually, the symbol that determines who owns the intellectual property is the logo of the company or corporation. The logo of a website is technically the logo of the brand which has the rights to all of the information represented on the site and ultimately the intellectual property of the site itself. Since there are various board members that usually make up the company that owns the intellectual property, the logo is a way of representing all of these members as a single entity.

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.

What is the advantage of using shortcuts
Answer: There can be advantages and disadvantages.
for example, if you were in the woods with a pathway, and a clear way that might be faster and a shorter way of getting out. You may take the shortcut leading to where you didn't want to go leading to you getting lost or, it could be the same time but with more challenges.
An example of shortcuts to it's advantage is when you're reading a text and you don't understand the word. It's much easier when you hear it being read out to you when the reader uses tone to kind of give you a hint if the connotation is negative or positive, A good example of this is the word unique let's use this sentence "She was very unique, and that's what made her cool!" We can use the words "cool" to see that unique is a positive connotation! For the word cool can usually mean that something is real nice or it's something/someone you'd typically like to be around. So therefore these are just a few examples of the advantages and disadvantages of shortcuts.
One problem with dynamic arrays is that once the array is created using the new operator the size cannot be changed. For example, you might want to add or delete entries from the array similar to the behavior of a vector. This project asks you to create a class called DynamicStringArray that includes member functions that allow it to emulate the behavior of a vector of strings.
The class should have:
A private member variable called dynamicArray that references a dynamic array of type string.
A private member variable called size that holds the number of entries in the array.
A default constructor that sets the dynamic array to NULL and sets size to 0.
A function that returns size.
A function named addEntry that takes a string as input. The function should create a new dynamic array one element larger than dynamicArray, copy all elements from dynamicArray into the new array, add the new string onto the end of the new array, increment size, delete the old dynamicArray, and then set dynamicArray to the new array.
A function named deleteEntry that takes a string as input. The function should search dynamicArray for the string. If not found, return false. If found, create a new dynamic array one element smaller than dynamicArray. Copy all elements except the input string into the new array, delete dynamicArray, decrement size, and return true.
A function named getEntry that takes an integer as input and returns the string at that index in dynamicArray. Return "" string if the index is out of dynamicArray’s bounds.
Overload the operator[] so that you can get and change an element by an index integer. If the index is out-of-bounds, return a "" string.
A copy constructor that makes a copy of the input object’s dynamic array.
Overload the assignment operator so that the dynamic array is properly copied to the target object.
A destructor that frees up the memory allocated to the dynamic array.
Create a suitable test program to test your class.
You should name the project ASG10. When you zip up the project folder, ASG10, include all the files (.sln, .cpp, etc) and subdirectories (Debug, etc.).
**************************************************
Copy your DynamicStringArray from Assignment 10. Fix the program so all 13 tests work properly. Modify the definition of the overloaded operator [] and getEntry so they throw an OutOfRange exception if an index that is out of range is used. OutOfRange is an exception class that you define. The exception class should have a private int member and a private string member, and a public constructor that has int and string arguments. The offending index value along with a message should be stored in the exception object. You choose the message to describe the situation. Modify your test program and add tests that catch the new exception class.
You should name the project ASG14. When you zip up the project folder, ASG14, include all the files (.sln, .cpp, etc) and subdirectories (Debug, etc.).
Answer:
Un problema con las matrices dinámicas es que una vez que se crea la matriz utilizando el nuevo operador, no se puede cambiar el tamaño. Por ejemplo, es posible que desee agregar o eliminar entradas de la matriz de manera similar al comportamiento de un vector. Este proyecto le pide que cree una clase llamada DynamicStringArray que incluye funciones miembro que le permiten emular el comportamiento de un vector de cadenas.
La clase debe tener:
Una variable miembro privada llamada dynamicArray que hace referencia a una matriz dinámica de tipo cadena.
Una variable de miembro privada llamada tamaño que contiene el número de entradas en la matriz.
Un constructor predeterminado que establece la matriz dinámica en NULL y establece el tamaño en 0.
Una función que devuelve el tamaño.
Una función llamada addEntry que toma una cadena como entrada. La función debe crear una nueva matriz dinámica un elemento más grande que dynamicArray, copiar todos los elementos de dynamicArray en la nueva matriz, agregar la nueva cadena al final de la nueva matriz, incrementar el tamaño, eliminar el antiguo dynamicArray y luego establecer dynamicArray en el nueva matriz.
Una función llamada deleteEntry que toma una cadena como entrada. La función debe buscar la cadena en dynamicArray. Si no lo encuentra, devuelva falso. Si lo encuentra, cree una nueva matriz dinámica con un elemento más pequeño que dynamicArray. Copie todos los elementos excepto la cadena de entrada en la nueva matriz, elimine DynamicArray, reduzca el tamaño y devuelva verdadero.
Una función llamada getEntry que toma un número entero como entrada y devuelve la cadena en ese índice en dynamicArray. Devuelve la cadena "" si el índice está fuera de los límites de dynamicArray.
Sobrecargue el operador [] para que pueda obtener y cambiar un elemento por un índice entero. Si el índice está fuera de los límites, devuelve una cadena "".
Un constructor de copia que hace una copia de la matriz dinámica del objeto de entrada.
Sobrecargue el operador de asignación para que la matriz dinámica se copie correctamente en el objeto de destino.
Un destructor que libera la memoria asignada a la matriz dinámica.
Cree un programa de prueba adecuado para evaluar su clase.
Debería nombrar el proyecto ASG10. Al comprimir la carpeta del proyecto, ASG10, incluya todos los archivos (.sln, .cpp, etc.) y subdirectorios (Debug, etc.).
************************************************
Copie su DynamicStringArray de la Tarea 10. Corrija el programa para que las 13 pruebas funcionen correctamente. Modifique la definición del operador sobrecargado [] y getEntry para que generen una excepción OutOfRange si se usa un índice que está fuera de rango. OutOfRange es una clase de excepción que define. La clase de excepción debe tener un miembro int privado y un miembro string privado, y un constructor público que tenga argumentos int y string. El valor del índice infractor junto con un mensaje deben almacenarse en el objeto de excepción. Tú eliges el mensaje para describir la situación. Modifique su programa de prueba y agregue pruebas que detecten la nueva clase de excepción.

Explanation:
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.

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.

A simple computer has a main memory and a disk but not a cache. If a referenced word is in main memory, 90ns are required to access it. If it is on disk but not in main memory, 10ms are needed to load it into main memory (this includes the time to originally check the main memory), and then reference is started again. The main memory hit ratio is 0.8. What is the average time in ns required to access a referenced word on this system
Answer:
The average time in ns to reference a work will be of 2,000,090.
Explanation:
80% of the time, you will need just to load from the main memory(when there is a hit), that is, a time of access of 90 ns.
20% of the time, you will have a miss, so you have to access the main memory(90 ns) plus the disk(10 ms = 10000000 ns).
So, the average time needed to reference a word will be:
[tex]t = 0.8*90 + 0.2*(90 + 10000000) = 2000090[/tex]
The average time in ns to reference a work will be of 2,000,090.
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 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

Write a for loop to print all NUM_VALS elements of vector courseGrades, following each element with a space (including the last). Print forwards, then backwards. End with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:
7 9 11 10
10 11 9 7
Hint: Use two for loops. Second loop starts with i-courseGrades.size() - 1 (Notes)
Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element vector (vector int> courseGrades(4)). See "How to Use zyBooks".
Also note: If the submitted code tries to access an invalid vector element, such as courseGrades at(9) for a 4-element vector, the test may generate strange results. Or the test may crash and report "Program end never reached', in which case the system doesn't print the test case that caused the reported message.

Explanation:
This line iterates through courseGrade in reverse order
for (i = courseGrades.size()-1; i >=0 ; i--) {
This prints each element of courseGrade in reverse followed by blank space
cout<<courseGrades.at(i)<<" ";
}

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.
