Rideshare companies like Uber or Lyft track the x,y coordinates of drivers and customers on a map. If a customer requests a ride

TiliK225 [7]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main (String[]args){

Scanner input = new Scanner(System.in);

double user[] = new double[2]; double dr1[] = new double[2];

double dr2[] = new double[2]; double dr3[] = new double[2];

System.out.print("Enter user coordinates: ");

for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }

System.out.print("Enter driver 1 coordinates: ");

for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }

System.out.print("Enter driver 2 coordinates: ");

for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }

System.out.print("Enter driver 3 coordinates: ");

for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }

double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);

double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);

double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);

System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");

System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");

System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");

}

Explanation:

The following array declarations are for the customer and the three drivers

<em> double user[] = new double[2]; double dr1[] = new double[2];</em>

<em> double dr2[] = new double[2]; double dr3[] = new double[2]; </em>

This prompts the user for the customer's coordinates

System.out.print("Enter user coordinates: ");

This gets the customer's coordinate

for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }

This prompts the user for the driver 1 coordinates

System.out.print("Enter driver 1 coordinates: ");

This gets the driver 1's coordinate

for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }

This prompts the user for the driver 2 coordinates

System.out.print("Enter driver 2 coordinates: ");

This gets the driver 2's coordinate

for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }

This prompts the user for the driver 3 coordinates

System.out.print("Enter driver 3 coordinates: ");

This gets the driver 3's coordinate

for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }

This calculates the distance between driver 1 and the customer

double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);

This calculates the distance between driver 2 and the customer

double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);

This calculates the distance between driver 3 and the customer

double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);

The following print statements print the estimated pickup time of each driver

<em> System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");</em>

<em> System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");</em>

<em> System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");</em>

We use analog and digital signals in our everyday lives with the radio, the cell phone and with our own computers. our computers and our cell phones are all digital now but radio's are still considered analog. Radio telescopes explore space by using radio waves and signals to almost like scan space and collect data like a sonar in a submarine.

Design a class that has an array of floating-point numbers. The constructor should accept an integer argument and dynamically al

attashe74 [19]

Answer:

See explaination for the code

Explanation:

Here is the code

class NumberArray

{

private:

float *aptr; // Pointer to the array

int arraySize; // Holds the array size

float max,min,avg;

public:

NumberArray(int); // Constructor

~NumberArray(); // Destructor

int size() const // Returns the array size

{ return arraySize; }

void storeNumber(float num,int ele);

float retrieveNumber(int ele);

float getHighest();

float getLowest();

float getAverage();

};

//*******************************************************

// Constructor for IntArray class. Sets the size of the *

// array and allocates memory for it. *

//*******************************************************

NumberArray::NumberArray(int s)

{

arraySize = s;

aptr = new float [s];

for (int count = 0; count < arraySize; count++)

*(aptr + count) = 0;

}

//******************************************************

// Destructor for IntArray class. *

//******************************************************

NumberArray::~NumberArray()

{

if (arraySize > 0)

delete [] aptr;

}

void NumberArray::storeNumber(float num,int ele)

{

if(ele<arraySize)

*(aptr+ele)=num;

}

float NumberArray::retrieveNumber(int ele)

{

}

float NumberArray::getHighest()

{

float high=*(aptr+0);

for(int i=1;i<arraySize;i++)

return high;

}

float NumberArray::getLowest()

{

float low=*(aptr+0);

for(int i=1;i<arraySize;i++)

return low;

}

float NumberArray:: getAverage()

{

float ag=0;

for(int i=1;i<arraySize;i++)

ag=ag/arraySize;

return ag;

}
