Answer:

Cycling, also called bicycling or biking, is the use of bicycles for transport, recreation, exercise or sport.[1] People engaged in cycling are referred to as "cyclists",[2] "bicyclists",[3] or "bikers".[4] Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadricycles, recumbent and similar human-powered vehicles (HPVs).

Cyclists in the 2009 Tro-Bro Léon race.

Police cyclists in London.

A woman cycling in Sri Lanka.

A bike lane in Amsterdam. Bike lanes are dedicated for cyclists and provide shelter from vehicle traffic.

Bicycles were introduced in the 19th century and now number approximately one billion worldwide.[5] They are the principal means of transportation in many parts of the world.

Cycling is widely regarded as an effective and efficient mode of transportation[6][7] optimal for short to moderate distances.

Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a reduced consumption of fossil fuels, less air or noise pollution, reduced greenhouse gas emissions,[8] and greatly reduced traffic congestion.[9] These have a lower financial cost for users as well as for society at large (negligible damage to roads, less road area required). By fitting bicycle racks on the front of buses, transit agencies can significantly increase the areas they can serve.[10]

In addition, cycling provides a variety of health benefits. The World Health Organization (WHO) states that cycling can reduce the risk of cancers, heart disease, and diabetes that are prevalent in sedentary lifestyles.[11][12] Cycling on stationary bikes have also been used as part of rehabilitation for lower limb injuries, particularly after hip surgery.[13] Individuals who cycle regularly have also reported mental health improvements, including less perceived stress and better vitality.[14]

Among the disadvantages of cycling are the requirement of bicycles (excepting tricycles or quadricycles) to be balanced by the rider in order to remain upright, the reduced protection in crashes in comparison to motor vehicles,[15] often longer travel time (except in densely populated areas), vulnerability to weather conditions, difficulty in transporting passengers, and the fact that a basic level of fitness is required for cycling moderate to long distances.

Create a new Java project/class called ChangeUp. Create an empty int array of size 6. Create a method called populateArray that

-Dominant- [34]

<h2>Answer:</h2><h2></h2>

//import the Random and Scanner classes

import java.util.Random;

import java.util.Scanner;

//Begin class definition

public class ChangeUp {

//Begin the main method

public static void main(String args[]) {

//Initialize the empty array of 6 elements

int [] numbers = new int [6];

//Call to the populateArray method

populateArray(numbers);

} //End of main method

//Method to populate the array and print out the populated array

//Parameter arr is the array to be populated

//Create object of the Random class to generate the random index

Random rand = new Random();

//Create object of the Scanner class to read user's inputs

Scanner input = new Scanner(System.in);

//Initialize a counter variable to control the while loop

int i = 0;

//Begin the while loop. This loop runs as many times as the number of elements in the array - 6 in this case.

while(i < arr.length){

//generate random number using the Random object (rand) created above, and store in an int variable (randomNumber)

int randomNumber = rand.nextInt(6);

//(Optional) Print out a line for formatting purposes

System.out.println();

//prompt user to enter a value

System.out.println("Enter a value " + (i + 1));

//Receive the user input using the Scanner object(input) created earlier.

//Store input in an int variable (inputNumber)

int inputNumber = input.nextInt();

//Store the value entered by the user in the array at the index specified by the random number

What classes should I take in high-school for majoring in computer science?

Gala2k [10]

Answer:

Computer science are the disciplines that study information, computing and the applications or ecosystems where they are developed. It is a science that comes from applied mathematics and has 3 branches that are quite well known. On the one hand we have software engineering, secondly theory as such (primary study of algorithms and data, etc.) and finally the application of the amalgam of the first two, which end up resulting in disciplines such as big data, cybersecurity or computer security, machine learning, artificial intelligence, etc. However, we are talking about a very broad science with various branches of work. Technological advances that have improved the scope of education, now allow us to develop in specific skills and computer science is one of the macro careers that have benefited the most thanks to the diversity of subjects it encompasses. This is where the on-demand courses available on the edX platform come in. Computer scientists are in one of the best times for their career advancement. We invite you to be part of the technological development and information and computing technologies through online courses.

Gala2k [10]

Answer:

Following is the program in C++ Language

#include <iostream> // header file

using namespace std; // namespace std

int main() // main method

{

int n; // variable declaration

cout<<" Please enter the number :";

cin>>n; // Read the number

if(n>0) // check the condition when number is positive

{

cout<<n<<endl<<"The number is Positive"; // Display number

}

else if(n<0) // check the condition when number is Negative

{

cout<<n<<endl<<"The number is Negative";// Display number

}

else // check the condition when number is Zero

{

cout<<n<<endl<<"The number is Zero";// Display number

}

return 0;

}

Output:

Please enter the number:

The number is Positive

Explanation:

Following are the description of the program

Declared a variable "n" of int type.
Read the value of "n" by user.
Check the condition of positive number by using if block statement .If n>0 it print the number is positive.
Check the condition of negative number by using else if block statement If n<0 it print the number is negative.
Finally if both the above condition is fail it print the message " The number is Zero"
