Give several reasons why Python is such a great programming language. Explain how Python is related to flowcharts.

Consider this program:
Cost1 = input("Please enter the first expense: ")
Cost2 = input("Please enter the second expense: ")
print("Your total for both expenses was", Cost1 + Cost2)
If the user inputs “10” for the first expense and “20” for the second expense, what will the interpreter show in the final line when this program is run? If this result in not what the programmer intended, how would you explain what went wrong?

You are writing a line of code that should ask the user to input the balance of their bank account in dollars and cents. The program will then perform a multiplication problem to tell the user how much interest they can earn. Identify three errors in your line of input code and explain why they are incorrect. Include the corrected line of code in your answer. Here is the code:
1num = input(What is your balance?)

What are some kinds of comments that might be useful for a programmer to include in a program?

If you were planning how to write a program, at what point would a flowchart be helpful? At what point would pseudocode be helpful? Explain your reasoning.

What are some kinds of comments that might be useful for a programmer to include in a program?

some kinds of comments that might be useful is when there is a bug, something that needs to be fixed, something that is easy to hack, and something the programmer needs to finish if the programmer released the program early.

If you were planning how to write a program, at what point would a flowchart be helpful? At what point would p s e u d o c o d e be helpful? Explain your reasoning.

A flowchart is helpful in the beginning of writing a program when you are planning what to do. The p s e u d o c o d e would be helpful before you start the coding. The reason is because flowcharts are helpful for planning out your course of action, while pseudocode helps you plan what you are going to write, so it should be right before you start coding, so you know everything that you were thinking about whilst writing the p s e u d o c o d e , and you know that if one thing doesn’t work, you still have all the previous thoughts on that line.

You are an IT consultant. You are visiting a new client's site to become familiar with their network. As you walk around their facility, you note the following: When you enter the facility, a receptionist greets you and directs you down the hallway to the office manager's cubicle. The receptionist uses a notebook system that is secured to her desk with a cable lock. The office manager informs you that the organization's servers are kept in a locked closet. Only she has the key to the closet. When you arrive on site, you will be required to get the key from her to access the closet. She informs you that server backups are configured to run each night. A rotation of external USB hard disks are used as the backup media. You notice that the organization's network switch is kept in an empty cubicle adjacent to the office manager's workspace. You notice that a router/firewall/content filter all-in-one device has been implemented in the server closet to protect the internal network from external attacks. Which security-related recommendations should you make to this client

Answers

Answer: • Control access to the work area with locking doors and card readers.

• Relocate the switch to the locked server closet

Explanation:

Based on the information given, the security-related recommendations that should be made to this client include:

• Relocate the switch to the locked server closet: Since the organization's network switch is kept in an empty cubicle that is adjacent to the office manager's workspace, it can be easily accessible by anyone and this could lead to an external attack. Therefore, it should be moved to the locked server closet to prevent external attack.

• Control access to the work area with locking doors and card readers- Thus us necessary so that the work area won't be accessible to just anybody.

The correct answer for each of the blanks in the given paragraph about commands and tools in computer are;

REPLACEHYPERLINKSDOCUMENT INSPECTOR COMPATIBILITY CHECKERACCESSIBILITY CHECKER

A) The commands that allows the user to quickly locate and replace a text are called find and replace commands because they are used to replace a certain character or text or group of texts with another.

B) The means by which you are allowed to easily navigate to places within or outside the document is called Hyperlinks. This is because that are used to give us a link to a new document or a related one outside of the current document.

C) The tool used to find out if your document contains personal information and comments is called Document inspector. This is because it aids in checking personal information and other hidden data information.

D) The tool to use if the person receiving your document has a pre-2010 version of Microsoft Word, is called Compatibility checker. This is because a compatibility checker would help to find out if a particular Word document is compatible with a previous version of Microsoft Word.

E) The tool to run to make sure your document can be read by devices for the visually impaired is called Accessibility checker as it has inbuilt codes to assist in checking if the document can be effectively utilized by people living with disabilities.

Assume the existence of a Window class with integer data members width and height. Overload the << operator for the Window class-- i.e., write a nonmember ostream-returning function that accepts a reference to an ostream object and a constant reference to a Window object and sends the following to the ostream: 'a (width x height) window' (without the quotes and with width and height replaced by the actual width and height of the window. Thus for example, if the window had width=80 and height=20, << would send 'a (80 x 20) window' to the ostream object.) Don't forget to have the function return the proper value as well. Assume the operator has been declared a friend in the Window class.

Answers

Answer:

Following are the code to the given question:

#include <iostream>//header file

using namespace std;

class Window //defining a class Window

{

private:

int width, height;//defining integer variable

public:

friend ostream& operator << (ostream& stm, Window& width)//defining a friend function that takes two parameters

{

return stm<<"a ("<<width.width<<" x "<<width.height<<") window"; //use return keyword that return its values

}  

Window(int width, int height): width(width), height(height)//defining parameterized constructor that inherit width and height in its parameters  

{}

};

int main() //Main method

{

Window w(80,90);//calling class constructor

cout<<w;//print object value

return 0;

}

Output:

a (80 x 90) window

Explanation:

In the above code, a class "Window" is defined that uses a friend function "ostream& operator" is declared that uses the "ostrea&" as a data type to hold two-variable "stm and w" in its parameter, and declared the parameterized constructor to hold value by inheriting width and height in its parameters.

Inside the main method, a class object is created that calls the constructor and uses the print method to print object value.

Explanation:

Start up a dialogue with the person to find out if they would be willing to take down the message, and find out why they did it as this could prevent a similar situation happening in the future.

Applying pressure though their peer group to conform to your standards is also a good measure to take as they would not want to feel left out.
