Answer:

The person watching Lances friend typing the atm pin is an example of <u>shoulder browsing</u>. Lances friend should <u>change the atm pin</u>.

Explanation:

Shoulder browsing is a technique that consists in looking over people's shoulder to get information like PINs and passwords. Because of this, this is what the person watching Lance's friend is doing.

Also, what Lance's friend should do is to change the pin because as the person already stole it, he can use it to withdraw the funds in his account. So, he has to change it to avoid that.

Create two classes. The first, named Sale, holds data for a sales transaction. Its private data members include the day of the m
olya-2409 [2.1K]

Answer:

A C++ program was used in creating two classes. the code is stated below.

Explanation:

Solution

The C++ program is executed below:

#include<iostream>

using namespace std;

//declare class (will be define later)

class Salesperson;

//class Sale

class Sale

{

  //private members of class

  private:

      string day;

      double amtOfSale;

      int salesPersonId;

 //public methods

  public:

      //constructor that takes day,amount of sale and salesPersonId as parameters

      Sale(string date,double sale,int id)

      {

          //set the private members to the initial values passed

          day=date;

          amtOfSale=sale;

          salesPersonId=id;

      }    

      //declare a friend function that takes objects of the two classes as parameters

      friend void display(Sale,Salesperson);

};  

//define class Salesperson

class Salesperson

{

  //private members of the class

  private:

      int salesPersonId;

      string lastName;    

  //public methods

  public:

      //constructor that takes name and id as parameters

      Salesperson(int id,string name)

      {

          //set the members of the class with the parameters passed

          salesPersonId=id;

          lastName=name;

      }  

      //declare a friend function that takes objects of the two classes as parameters

      friend void display(Sale,Salesperson);

};

//define the friend funtion

void display(Sale saleObj,Salesperson personObj)

{

  //display the sales info using the objects of the two classes

  cout<<"\nSale #"<<saleObj.salesPersonId<<" on "<<saleObj.day<<" for $"<<saleObj.amtOfSale<<" sold by #"<<personObj.salesPersonId<<" "<<personObj.lastName;

}  

int main()

{

  //create object for Sale class and pass default values

  Sale sObj1("12/25/2016",559.95,103);

  //create object for Salesperson class and pass default values

  Salesperson pObj1(103,"Woods");

 

  //create another object for Sale class and pass default values

  Sale sObj2("11/15/2016",359.95,106);

  //create another object for Salesperson class and pass default values

  Salesperson pObj2(106,"Hansen");

  //using the friend function dislay the sales info

  display(sObj1,pObj1);

  display(sObj2,pObj2);

  return 0;

Write code which takes a sentence as an input from the user and then prints the length of the first word in that sentence.
Afina-wow [57]

import java.util.Scanner;

public class U2_L3_Activity_Four {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter a sentence.");

       String sent = scan.nextLine();

       int count = 0;

       for (int i = 0; i < sent.length(); i++){

           char c = sent.charAt(i);

           if (c != ' '){

               count++;

       }

           else{

               break;

           }

       

   }

       System.out.println("The first word is " + count +" letters long");

   

   }

}

We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!

The program DebugTwo2.cs has syntax and/or logical errors. Determine the problem(s) and fix the program.// This program greets t
Elenna [48]

Answer:

The corrected code is as follows:

using System;

using static System.Console;

class DebugTwo2{

     static void Main(string[] args){

       string name;string firstString, secondString;

       int first, second, product;

       Write("Enter your name >> ");

       name = ReadLine();

       Write("Hello, {0}! Enter an integer >> ", name);

       firstString = ReadLine();

       first = Convert.ToInt32(firstString);

       Write("Enter another integer >> ");

       secondString = ReadLine();

       second = Convert.ToInt32(secondString);

       product = first * second;

       Write("Thank you, {0}. The product of {1} and {2} is {3}", name,first, second, product);

   }

}

Explanation:

       string name;string firstString, secondString; ----- Replace secondSting with secondString,

<em>        int first, second, product;</em>

       Write("Enter your name >> "); --- Here, the quotes must be closed with corresponding quotes "

       name = ReadLine(); The syntax of readLine is incorrect without the () brackets

<em>        Write("Hello, {0}! Enter an integer >> ", name);</em>

<em>        firstString = ReadLine();</em>

       first = Convert.ToInt32(firstString); There is a dot between Convert and ToInt32

<em>        Write("Enter another integer >> ");</em>

       secondString = ReadLine(); --- Readline() should be written as ReadLine()

<em>        second = Convert.ToInt32(secondString);</em>

<em>        product = first * second;</em>

       Write("Thank you, {0}. The product of {1} and {2} is {3}", name,first, second, product); --- The formats in {} should start from 0 because 0 has already been initialized for variable name

   }
