Write a while loop that prints usernum divided by 2 until user_num is less than 1. The value of user_num changes inside of the l

zaharov [31]

Answer:

The program to this question can be describes as follows:

Program:

#include <iostream> //defining header file

using namespace std;

int main() //defining main method

{

float user_num ;//defining float variable

cout<<"Enter any number: "; //message

cin>>user_num; //input value from the user

while (user_num >= 1) //defining loop to calculate value

{

user_num =user_num/ 2; //diving the value

cout<<user_num<<endl; //print value

}

return 0;

}

Output:

Enter any number: 20

10

5

2.5

1.25

0.625

Explanation:

In the above program, a float variable user_num is declared in which we store input value from the user end, in the next step, a while loop is declared, which calculates, the given value.

In the loop a condition is defined, that user_num value is greater than equal to 1, inside the loop it will divide the value of the user_num and store in this variable.
In this print, the method is used, which prints its variable values.

Suppose that you need to maintain a collection of data whose contents are fixed- i.e., you need to search for and retrieve exist

Keith_Richards [23]

Answer:

Option a: a sorted array

Explanation:

Since the expectation on the data structure never need to add or delete items, a sorted array is the most desirable option. An array is known for its difficulty to modify the size (either by adding item or removing item). However, this disadvantage would no longer be a concern for this task. This is also the reason, linked list, binary search tree and queue is not a better option here although they offer much greater efficiency to add and remove item from collection.

On another hand, any existing items from the sorted array can be easily retrieved using address indexing and therefore the data query process can be very fast and efficient.

Imagine a business where there are no clear boundaries defined for data and systems ownership. As a security professional, descr

laiz [17]

Answer:

Loss of confidentiality, integrity and Availability

Explanation:

First I would start by explaining data ownership and system ownership

Data ownership:

Such an owner is responsible for safeguarding data, has all rights and complete control of the data. He or she can transfer data responsibility to someone else

System ownership:

The responsibility here is system maintenance, taking care of system functionalities, updating system and system software.

Lack of data ownership:

1. This affects privacy of data as there would be no one involved in the monitoring and taking care of the data. It would be at risk as sensitive information may get out and data may even be modified.

2. Lack of data ownership could bring about inconsistency in data

3. Lack of data ownership piles up risks to data which may cause great loss to data eventually.

Lack of system ownership:

1. There would be no one available to take care of issues that may come up with the system

2. If system gets to be outdated, it becomes open to malware and hackers

3. Work will be unable to be completed on the system.

Loss of CIA triad

CIA stands for confidentiality, Integrity and Availability

1. Without data ownership there would be access to data which is unauthorized. This brings about loss in confidentiality, and there could be issues with data availability

2. If system gets malware at the absence of system owner then there would be loss in confidentiality, integrity. Hackers would take control of the system and they would be able to use data.

Write a program that uses the Purchase class in 5.13. Set the prices to the following: Oranges: 10 for $2.99 Eggs: 12 for $1.69

Xelga [282]

Answer:

Explanation:

The following program is written in Java. Using the program code from Purchase class in 5.13 I created each one of the fruit objects. Then I set the price for each object using the setPrice method. Then I set the number of each fruit that I intended on buying with the setNumberBought method. Finally, I called each objects getTotalCost method to get the final price of each object which was all added to the totalCost instance variable. This instance variable was printed as the total cost of the bill at the end of the program. My code HIGHLIGHTED BELOW

//Entire code is in text file attached below.

//MY CODE HERE

DecimalFormat df = new DecimalFormat("0.00");

oranges.setPrice(10, 2.99);

oranges.setNumberBought(2*12);

eggs.setPrice(12, 1.69);

eggs.setNumberBought(2*12);

apples.setPrice(3, 1);

apples.setNumberBought(20);

watermelons.setPrice(1, 4.39);

watermelons.setNumberBought(2);

bagels.setPrice(6, 3.50);

bagels.setNumberBought(12);

totalCost = oranges.getTotalCost() + eggs.getTotalCost() + apples.getTotalCost() + watermelons.getTotalCost() + bagels.getTotalCost();

System.out.println("Total Cost: $" + df.format(totalCost));

}

Why is continual user involvement a useful way to discover system requirements? Under what conditions might it be used? Under wh

True [87]

Answer:

continual user involvement gives the flexibility to analyze the requirements in right direction. because there is continuous meetings with the end user and he can provide right direction or avoids wrong interpretation of the requirement

Explanation:

continual user involvement is useful when we are following agile methodology where we are building complex systems. it is not useful for simple sytems and following waterfall methodology
