Answer:
The program is as follows:
#include <iostream>
using namespace std;
int main(){
double pi = 3.14;
int choice1, choice2;
double Length, Width, Height, Radius, Base;
double side1, side2, side3;
cout<<"Length: "; cin>>Length;
cout<<"Width: "; cin>>Width;
cout<<"Height: "; cin>>Height;
cout<<"Radius: "; cin>>Radius;
cout<<"Base: "; cin>>Base;
cout<<"Press 1 to calculate Area\nPress 2 to calculate Perimeter\n";
cin>>choice1;
if(choice1 == 1){
cout<<"Press 1 for Rectangle\nPress 2 for Triangle\nPress 3 for Circle\n";
cin>>choice2;
if(choice2 == 1){ cout<<"Area: "<<Length * Width; }
else if(choice2 == 2){ cout<<"Area: "<<0.5 * Base * Height; }
else if(choice2 == 3){ cout<<"Area: "<<pi * Radius * Radius; }
else{cout<<"Invalid choice";} }
else if(choice1 == 2){
cout<<"Press 1 for Rectangle\nPress 2 for Triangle\nPress 3 for Circle\n";
cin>>choice2;
if(choice2 == 1){ cout<<"Perimeter: "<<2 * (Length + Width); }
else if(choice2 == 2){
cout<<"Side 1: "; cin>>side1;
cout<<"Side 2: "; cin>>side2;
cout<<"Side 3: "; cin>>side3;
cout<<"Perimeter: "<<side1+side2+side3; }
else if(choice2 == 3){ cout<<"Perimeter: "<<2 * pi * Radius; }
else{cout<<"Invalid choice";} }
return 0;}
Explanation:
This initializes pi as 3.14
double pi = 3.14;
The next three lines declare all variables
int choice1, choice2;
double Length, Width, Height, Radius, Base;
double side1, side2, side3;
The next 5 lines get inputs
cout<<"Length: "; cin>>Length;
cout<<"Width: "; cin>>Width;
cout<<"Height: "; cin>>Height;
cout<<"Radius: "; cin>>Radius;
cout<<"Base: "; cin>>Base;
This prompts the user for choice 1 (area or perimeter)
cout<<"Press 1 to calculate Area\nPress 2 to calculate Perimeter\n";
This gets input for choice 1
cin>>choice1;
If choice 1 is 1, then area is calculated
if(choice1 == 1){
This prompts the user for choice 2 (rectangle, triangle or circle)
cout<<"Press 1 for Rectangle\nPress 2 for Triangle\nPress 3 for Circle\n";
This gets input for choice 2
cin>>choice2;
Calculate area of rectangle if rectangle is selected
if(choice2 == 1){ cout<<"Area: "<<Length * Width; }
Calculate area of triangle if triangle is selected
else if(choice2 == 2){ cout<<"Area: "<<0.5 * Base * Height; }
Calculate area of circle if circle is selected
else if(choice2 == 3){ cout<<"Area: "<<pi * Radius * Radius; }
Print invalid choice for all other inputs
else{cout<<"Invalid choice";} }
If choice 1 is 2, then perimeter is calculated
else if(choice1 == 2){
This prompts the user for choice 2 (rectangle, triangle or circle)
cout<<"Press 1 for Rectangle\nPress 2 for Triangle\nPress 3 for Circle\n";
This gets input for choice 2
cin>>choice2;
Calculate perimeter of rectangle if rectangle is selected
if(choice2 == 1){ cout<<"Perimeter: "<<2 * (Length + Width); }
Calculate perimeter of triangle if triangle is selected
else if(choice2 == 2){
Get input for the three sides of the triangle
cout<<"Side 1: "; cin>>side1;
cout<<"Side 2: "; cin>>side2;
cout<<"Side 3: "; cin>>side3;
cout<<"Perimeter: "<<side1+side2+side3; }
Calculate perimeter of circle if circle is selected
else if(choice2 == 3){ cout<<"Perimeter: "<<2 * pi * Radius; }
Print invalid choice for all other inputs
else{cout<<"Invalid choice";} }
return 0;

When in global configuration mode, which steps are necessary to edit an ip address on an Ethernet interface?
Answer:
I. You should enter interface configuration mode.
II. Configure the IP address and subnet mask.
Explanation:
A node refers to the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.
Some examples of network nodes are modem, hubs, computer, switches, phone and printers.
In Computer networking, network devices such as routers and switches are usually configured (programmed) through the use of specific network commands commonly referred to as configs e.g show int description, config terminal (config t), show IP address, etc.
In Cisco devices, there are five (5) main types of command modes;
1. Sub-interface configuration mode.
2. Interface configuration mode.
3. Line configuration mode.
4. Router configuration method.
5. Global configuration mode.
Global configuration mode is a configuration mode that avail network engineers and end users with the ability to modify or edit the running (global) system configuration of a networking device. Thus, any change effected at the global configuration mode will affect the network device as a whole.
In global configuration mode, the steps which are necessary to edit an ip address on an Ethernet interface include;
I. You should enter interface configuration mode using the "configure terminal" command.
II. Configure the IP address and subnet mask.
See an example below;
"Router(config-if)# IP address 192.168.1.2 255.255.255.0"

It's currently 1:00 in the afternoon. You want to schedule the myapp program to run automatically tomorrow at noon (12:00). What two at commands could you use
Answer:
at 12 pm tomorrow
at now +23 hours
Explanation:
The at command could be used in the command line to perform a scheduled command in Unix related systems. The at command coule be ua d to program a complex script or used to perform simple scheduled reminders.
The at command is initiated by first writing the at string followed by the condition or statement to be performed.
Currently (1:00 pm) ; To make a schedule for 12pm then that will be at noon the following day:
at 12:00 pm tomorrow
Or :
Using the number of hours between the current tone and the schedule time : 12 pm tomorrow - 1:00 pm today is a difference of 23 hours ;
Hence, it can be written as :
at +23 hours

major characteristics of the bus in computer architecture
Answer:
A bus is characterized by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel.
In computer architecture, a bus (related to the Latin “omnibus”, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.)

two reasons for compressing files before uploading them to cloud storage
Answer:
Storage. File compression reduces the amount of space needed to store data. Using compressed files can free up valuable space on a hard drive, or a web server. Some files, like word files, can be compressed to 90 percent of their original size.
Explanation:
The main advantages of compression are reductions in storage hardware, data transmission time, and communication bandwidth. This can result in significant cost savings. Compressed files require significantly less storage capacity than uncompressed files, meaning a significant decrease in expenses for storage.
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain fewer than 20 integers.
Ex: If the input is
5 50 60 140 200 75 100
the output is
50 60 75
Answer:
The program in Python is as follows:
num = int(input())
numList = []
for i in range(num+1):
numInput = int(input())
numList.append(numInput)
for i in range(len(numList)-1):
if numList[i] <= numList[-1]:
print(numList[i],end=" ")
Explanation:
This gets input for the number of integers
num = int(input())
This initializes an empty list
numList = []
This iterates through the number of integers and gets input for each
for i in range(num+1):
numInput = int(input())
The inputs including the threshold are appended to the list
numList.append(numInput)
This iterates through the list
for i in range(len(numList)-1):
All inputs less than or equal to the threshold are printed
if numList[i] <= numList[-1]:
print(numList[i],end=" ")

User-Defined Functions: Miles to track lapsOne lap around a standard high-school running track is exactly 0.25 miles. Define a function named MilesToLaps that takes a float as a parameter, representing the number of miles, and returns a float that represents the number of laps.Then, write a main program that takes a number of miles as an input, calls function MilesToLaps() to calculate the number of laps, and outputs the number of laps. Ex: If the inout is 1.5the output is 6.0 Ex: If the input is 2.2the output is 8.8 Your program should define and call a function Function Miles ToLaps(float userMiles) returns float userLaps 12 // Deine Milestola hert. 34 // Deine Minhert. Your code ust call llestola 5
Answer:
Explanation:
The following is written in Java. The MilesToLaps method creates a variable called laps and gives it the value of the input parameter miles divided by 0.25. Then it returns the variable laps to the user. In the main method a Scanner object was created and asks the user for the number of miles which are passed to the MilesToLaps method which returns the number of laps. This can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("How many miles?");
float miles = in.nextFloat();
System.out.println("This is " + MilesToLaps(miles) + " laps");
}
public static float MilesToLaps(float miles) {
float laps = (float) (miles / 0.25);
return laps;
}
}
This criterion is linked to a Learning OutcomeCreate checkDuplicates method that receives an array of ints, and an int as parameters. It will return true if the int is found in the array, and false if the int is NOT found in the array. Call the checkDuplicates method from both the MegaMillionsLottery constructor, and the getUserPicks() method.
Answer:
Explanation:
The MegaMillions Lottery class was not provided and neither was the getUserPicks() method. Since they were not found online either, I have created the checkDuplicates method so that it works standalone. Therefore, you can simply call the method from wherever you need by pasting the call line where it needs to be called. A test case has been created in the main method so that you can see the method in action. The output is seen in the attached image below.
public static boolean checkDuplicate(int[] myArr, int element) {
for (int x : myArr) {
if (x == element) {
return true;
}
}
return false;
