Lesson 3 - Calling All Operators

In this exercise you will debug the code which has been provided in the starter file. The code is intended to do the following:

abruzzese [7]

Answer:

The corrected code is as follows:

import java.util.Scanner;

public class U2_L4_Activity_Two{

public static void main(String[] args){

Scanner scan = new Scanner(System.in);

String str1 = scan.nextLine();

String str2 = str1;

str1 = str1.toUpperCase();

System.out.println(str1);

System.out.println(str2);

}

Explanation:

This corrects the scanner object

Scanner scan = new Scanner(System.in);

This line is correct

String str1 = scan.nextLine();

This copies str1 to str2

String str2 = str1;

This converts str1 to upper case

str1 = str1.toUpperCase();

This prints str1

System.out.println(str1);

This prints str2

System.out.println(str2);

Define an organizational unit in your own words.

Musya8 [376]

Explanation:

An organizational unit (OU) is a subdivision within an Active Directory (hierarchical collection of network resources that can contain users, computers, printers, and other Active Directories) into which you can place users, groups, computers, and other organizational units. Each domain can implement its own organizational unit hierarchy, typically used either to differentiate between objects with the same name, or to parcel out authority to create and manage objects.

I hope you find this information useful and interesting! Good luck!

Write a function named “createPurchaseOrder” that accepts the quantity (integer), the cost per item(double), and the description

Leona [35]

#include
Program: using namespace std;
string createPurchaseOrder0;
int main(
{
cout<return 0;
}
string createPurchaseOrder(
{
int qty;
double costPerltem;
string description,info="":
cout<<"Enter Quantity:
cin>>qty;
cout<<"Enter cost per item: "
cin>>costPerltem;
cout<<"Enter Description: "
cin>>description;
if(qty<0 I| costPerltem<0
Idescription.compare(''"')==0)
cout<<'InThe entered data is invalid!":
info="":
else
"
cout<<"'InThe entered data is valid!":
info=info+"'(nQuantity: "+to_string (qty) +" In";
info=info+"Cost per item:
"†to_string (costPerltem)+"In";
info=info+"Description: "description+" In";

Assume that a gallon of paint covers about 350 square feet of wall space. Create an application with a main() method that prompt

Makovka662 [10]

Answer:

#include <iostream>

#include <cmath>

using namespace std;

///////////////////////////////////////////////////////////////////////

int noOfGallons(int wallArea) {

int gallon = 350;

int gallon_price = 32.0;

float total_price = 0.0;

///////////////////////////////////////////

float noOfGallons = (float)wallArea/(float)gallon;

printf("No of gallons needed %.2f", noOfGallons);

cout<<endl;

//////////////////////////////////////////

total_price = noOfGallons*gallon_price;

return round(total_price);

}

int wallArea(int length, int width, int height) {

int wall_area = length*width;

int total_price = noOfGallons(wall_area);

}

///////////////////////////////////////////////////////////////////////

int main() {

int length, width, height;

///////////////////////////////////////////

cout<<"Enter length: ";

cin>>length;

cout<<"Enter width: ";

cin>>width;

cout<<"Enter height: ";

cin>>height;

cout<<endl;

///////////////////////////////////////////

int total_price = wallArea(length, width, height);

cout<<"Total price: $"<<total_price;

///////////////////////////////////////////

return 0;
