5. Create a vector called to20 that goes from 1 to 20 (use the range notation). Now create a variable called end that goes from

40 to 50 (use the range notation). Now create a variable called to50 that combines to20, then the number 21 to 30 and then add thes end variable at the end. Now print the variable to50. It should output the numbers 1 through 30 and then 40 through 50, skipping 31-39.

code:  

to20 <-c(1:20) #creating to20 vector

end <-c(40:50) #creating end vector

to50 <-c(to20,21:30,end) # creating to50 vector

Use JavaWrite a program that will simulate a change machine found at cash registers. Input the amount due and amount paid from t
Ksju [112]

Answer:

Here is the JAVA program:

import java.util.Scanner;  //to accept input from user

public class Main { // class name

 public static void main(String [] args) {  // start of main method

   Scanner input = new Scanner(System.in);  // creates Scanner class object to take input from user

   System.out.println("Please Enter the Cost of the Item: ");  // prompts user to enter the cost of item

   double itemCost = input.nextDouble();  //scans and reads the input value of item cost

   System.out.println("Please Enter the Amount Paid: ");  // prompts user to enter the amount paid

   double amount = input.nextDouble();  //scans and reads the value of amount from user

   int change = (int)(amount * 100 - itemCost * 100);  //compute the remaining amount i.e. change

   System.out.println("Change Owed: " + change / 100.0);  // displays the owed change

   int quarters = change / 25;  // computes the value for quarters

   change = change % 25;  // compute the quarters remaining

   int dimes = change / 10;  //  computes dimes

   change = change % 10;  //  computes dimes remaining

   int nickels = change / 5;  // computes nickels

   change = change % 5;  // compute nickels remaining

   int pennies = change;  // computes pennies

   System.out.println("Quarters: " + quarters);  // displays computed value of quarters

   System.out.println("Dimes: " + dimes);  // displays value of dimes

   System.out.println("Nickels: " + nickels);  // displays value of nickels

   System.out.println("Pennies: " + pennies);   }} //displays value of pennies

Explanation:

I will explain the program with an examples.

Suppose the user enters 4.57 as cost of the item and 5.00 as amount paid. Then the program works as follows:

Change is computed as

change = (int)(amount * 100 - itemCost * 100);

This becomes;

change = (int)(5.00 * 100 - 4.57 * 100)

            = 500 - 457

change = 43

Now the change owed is computed as:

change / 100.0 = 43/100.0 = 0.43

Hence change owed = 0.43

Next quarters are computed as:

quarters = change / 25;

This becomes:

quarters = 43/25

quarters = 1

Now the remaining is computed as:

   change = change % 25;

This becomes:

   change = 43 % 25;

  change = 18

Next the dimes are computed from remaining value of change as:

dimes = change / 10;

dimes = 18 / 10

dimes = 1

Now the remaining is computed as:

   change = change % 10;

This becomes:

   change = 18 % 10

  change = 8

Next the nickels are computed from remaining value of change as:

nickels = change / 5;

nickels = 8 / 5

nickels = 1

Now the remaining is computed as:

   change = change % 5;

This becomes:

   change = 8 % 5

  change = 3

At last the pennies are computed as:

pennies = change;

pennies = 3

So the output of the entire program is:

Change Owed: 0.43                                                                                                                Quarters: 1                                                                                                                      Dimes: 1                                                                                                                         Nickels: 1                                                                                                                       Pennies: 3

Use the Date object and the Array object to determine and diplay information about the current date on your webpage. Your output
Mnenie [13.5K]

Answer:

  1. var today = new Date();
  2. var dateComp = [];
  3. dateComp[0] = today.getDate();
  4. dateComp[1] = today.getMonth();
  5. dateComp[2] = today.getFullYear();
  6. switch(dateComp[1]){
  7.    case 0:
  8.        console.log("Jan " + dateComp[0] + "," + dateComp[2])
  9.        break;
  10.    case 1:
  11.        console.log("Feb " + dateComp[0] + "," + dateComp[2])
  12.        break;
  13.    case 2:
  14.        console.log("Mar " + dateComp[0] + "," + dateComp[2])
  15.        break;
  16.    case 3:
  17.        console.log("Apr " + dateComp[0] + "," + dateComp[2])
  18.        break;
  19.    case 4:
  20.        console.log("May " + dateComp[0] + "," + dateComp[2])
  21.        break;
  22.    case 5:
  23.        console.log("Jun " + dateComp[0] + "," + dateComp[2])
  24.        break;
  25.    case 6:
  26.        console.log("Jul " + dateComp[0] + "," + dateComp[2])
  27.        break;
  28.    case 7:
  29.        console.log("Aug " + dateComp[0] + "," + dateComp[2])
  30.        break;
  31.    case 8:
  32.        console.log("Sept " + dateComp[0] + "," + dateComp[2])
  33.        break;
  34.    case 9:
  35.        console.log("Oct " + dateComp[0] + "," + dateComp[2])
  36.        break;
  37.    case 10:
  38.        console.log("Nov " + dateComp[0] + "," + dateComp[2])
  39.        break;
  40.    case 11:
  41.        console.log("Dec " + dateComp[0] + "," + dateComp[2])
  42.        break;
  43. }

Explanation:

The solution code is written in JavaScript.

Firstly, create a Date object (Line 1). The date object will automatically capture the current date and time.

Next create an array dateComp to hold the day, month and year (Line 3 -5). We use the getDate method to get current day, getMonth method for current month and getFullYear method for current year.

This is important to note that the getMonth method will return the value range from 0 - 11 with the Jan is represented as 0, Feb is 1 and so forth. Presume we intend to display the date using the format "month day, year", we can create a switch structure to check the month value which is range from 0 to 11. If month value is 0, generate string Jan + current day + "," + current year. We generate the date string based on different switch cases (7 - 44). We shall see the output similar to the date string as shown below:
