What is the purpose of the " + " in the code labeled // line 2 below ?
int sum;
int num1 = 3;
int num2 = 2;
sum = num1 + num2; // line 1
System.out.println(num1 + " + " + num2 + " = " + sum);// line 2
Answer:
To illustrate addition operation
Explanation:
Given
The above code segment
Required
Determine the purpose of "+" in label line 2
In line 2, num1 = 3 and num2 = 2 in line 3.
sum = 2 + 3 = 5 in line 4
From the given code segment, the plus sign is used as a string literal (i.e. "+").
This means that, the print statement will output: 3 + 2 = 5
The "+" is printed in between 3 and 2.
So, the purpose of the "+" is to show the function of the program and the function of the program is to illustrate an addition operation between two variables
Build a class and a driver for use in searching your computer’s secondary storage (hard disk or flash memory) for a specific file from a set of files indicated by a starting path. Lets start by looking at a directory listing. Note that every element is either a file or a directory.
Introduction and Driver
In this assignment, your job is to write a class that searches through a file hierarchy (a tree) for a specified file. Your FindFile class will search a directory (and all subdirectories) for a target file name.
For example, in the file hierarchy pictured above, the file "lesson.css" will be found once in a directory near the root or top-level drive name (e.g. "C:\") . Your FindFile class will start at the path indicated and will search each directory and subdirectory looking for a file match. Consider the following code that could help you build your Driver.java:
String targetFile = "lesson.css";
String pathToSearch ="
C:\\WCWC"; FindFile finder = new FindFile(MAX_NUMBER_OF_FILES_TO_FIND);
Finder.directorySearch(targetFile, pathToSearch);
File Searching
In general, searching can take multiple forms depending on the structure and order of the set to search. If we can make promises about the data (this data is sorted, or deltas vary by no more than 10, etc.), then we can leverage those constraints to perform a more efficient search. Files in a file system are exposed to clients of the operating system and can be organized by filename, file creation date, size, and a number of other properties. We’ll just be interested in the file names here, and we’ll want perform a brute force (i.e., sequential) search of these files looking for a specific file. The way in which we’ll get file information from the operating system will involve no ordering; as a result, a linear search is the best we can do. We’d like to search for a target file given a specified path and return the location of the file, if found. You should sketch out this logic linearly before attempting to tackle it recursively.
FindFile Class Interface
FindFile(int maxFiles): This constructor accepts the maximum number of files to find.
void directorySearch(String target, String dirName): The parameters are the target file name to look for and the directory to start in.
int getCount(): This accessor returns the number of matching files found
String[] getFiles(): This getter returns the array of file locations, up to maxFiles in size.
Requirements
Your program should be recursive.
You should build and submit at least two files: FindFile.java and Driver.java.
Throw an exception (IllegalArgumentException) if the path passed in as the starting directory is not a valid directory.
Throw an exception if you've found the MAX_NUMBER_OF_FILES_TO_FIND and catch and handle this in your main driver. Your program shouldn't crash but rather exit gracefully in the unusual situation that we've discovered the maximum number of files we were interested in, reporting each of the paths where the target files were found.
The only structures you can use in this assignment are basic arrays and your Stack, Queue, or ArrayList from the previous homeworks. Do not use built-in data structures like Java's ArrayList. To accomplish this, put in the following constructor and method to your ArrayList, Stack, or Queue:
public ArrayList(Object[] input) { data = input;
numElements = input.length;
}
public Object get(int index) {
return data[index];
}

what is the impact of technology to the mankind
Modern technology has revolutionized the way people all over the world communicate and interact. This revolution has led to a system of globalization which has fundamentally changed modern society in both good and bad ways.
The most important technological change over the past 20 years is the advent and popularization of the Internet. The Internet connects billions of people around the globe and allows a type of connectivity in ways which the world has never seen. Companies are able to do business with consumers from other countries instantaneously, friends and families are able to talk to one another and see each other regardless of location, and information sits at the fingertips of every person with a computer, tablet or phone.
Outside of the digital world, modern advances in machinery and science have also impacted everyday life. The modernization of travel has allowed humans to span more miles in their lifetime than at any point in history, and the advancement of medicine has given people longer lifespans.
While these changes have certainly been for the better, there are also plenty of negative results of modernization and globalization. Because the Internet streamlines massive amounts of information, it can easily be exploited. The loss of privacy is one of the most pressing issues in the modern world.
Technology has also had an impact on the natural world. Industrialization has led to the destruction of natural life and has possibly caused negative effects on our climate.

Answer:
Equity Shares are commonly called Common shares and have both advantages and disadvantages over Preference shares.
Equity shareholders are allowed to vote on company issues while preference shareholders can not.Preference shareholders get paid first between the two in the case that the company liquidates from bankruptcy. Preference shareholders get a fixed dividend that has to be paid before equity share dividends are paid. Preference shareholders can convert their shares to Equity shares but equity shareholders do not have the same courtesy.Preference shares can only be sold back to the company while equity shares can be sold to anybody.What is the major difference between the intranet and extranet?

:)Extend the functionality of cout by implementing a friend function in Number.cpp that overloads the insertion operator. The overloaded insertion operator returns an output stream containing a string representation of a Number object. The string should be in the format "The value is yourNum", where yourNum is the value of the integer instance field of the Number class.Hint: the declaration of the friend function is provided in Number.h.Ex: if the value of yourNum is 723, then the output is:
Answer:
// In the number.cpp file;
#include "Number.h"
#include <iostream>
using namespace std;
Number::Number(int number)
{
num = number;
}
void Number::SetNum(int number)
{
num = number;
}
int Number::GetNum()
{
return num;
}
ostream &operator<<(ostream &out, const Number &n)
{
out << "The value is " << n.num << endl;
return out;
}
// in the main.cpp file;
#include "Number.cpp"
#include <iostream>
using namespace std;
int main()
{
int input;
cin >> input;
Number num = Number(input);
cout << num;
return 0;
}
Explanation:
The main function in the main.cpp file prompts the user for the integer value to be displayed. The Number file contains defined functions and methods of the number class to set, get and display the "num" variable.
Ram and Hari can finish a piece of work in 6 days and 12 days respectively in how many days will they finish it working together
Answer:
4 days
Explanation:
Given - Ram and Hari can finish a piece of work in 6 days and 12 days
respectively.
To find - In how many days will they finish it working together
Proof -
As given,
Ram and Hari can finish a piece of work in 6 days and 12 days respectively.
⇒1 day work of Ram done in = [tex]\frac{1}{6}[/tex]
1 day work of Hari done in = [tex]\frac{1}{12}[/tex]
If they work together,
1 day work of both together done in = [tex]\frac{1}{6}[/tex] + [tex]\frac{1}{12}[/tex] = [tex]\frac{2 + 1}{12} = \frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]
As we know Work is inversely proportional to efficiency
And efficiency = Person's 1 day work
As we have ,
1 day work of both together done in = [tex]\frac{1}{4}[/tex]
⇒ Total work done in 4 days if they work together.

if 100 KB file is stored in 2 MB folder how many files can be stored in the folder
Answer:
20 files.
Explanation:
Given the following data;
Size of file = 100 kilobytes.
Folder size (memory) = 2 megabytes.
Method 1
1000 kilobytes = 1 megabytes.
100 kilobytes = x megabytes
Cross-multiplying, we have;
1000x = 100
x = 100/1000
x = 0.1 mb
Now, to find the number of files that can be stored;
[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]
Substituting into the equation, we have;
[tex] Number \; of \; files = \frac {2}{0.1} [/tex]
Number of files = 20 files.
Method II
We know that;
1 kilobytes = 0.001 megabytes. 100 kilobytes = 0.1 megabytes. 1000 kilobytes = 1 megabytes. 2000 kilobytes = 2 megabytes.Substituting into the formula, we have;
[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]
Substituting into the equation, we have;
[tex] Number \; of \; files = \frac {2000}{100} [/tex]
Number of files = 20 files.
The Westfield Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms. To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carpet. For example, the area of floor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpet that costs $8 per square foot would cost $960. (12 × 10 × 8 = 960.) First, you should create a class named RoomDimension that has two FeetInches objects as attributes: one for the length of the room and one for the width. (You should use the version of the FeetInches class that you created in Programming Challenge 11 with the addition of a multiply member function. You can use this function to calculate the area of the room.) The RoomDimension class should have a member function that returns the area of the room as a FeetInches object. Next, you should create a RoomCarpet class that has a RoomDimension object as an attribute. It should also have an attribute for the cost of the carpet per square foot. The RoomCarpet class should have a member function that returns the total cost of the carpet. Once you have written these classes, use them in an application that asks the user to enter the dimensions of a room and the price per square foot of the desired carpeting. The application should display the total cost of the carpet.
Answer:
Answered below
Explanation:
#program is written in Java
class RoomDimension{
double length;
double width;
RoomDimension (double length, double width){
this.length = length;
this.width = width;
}
public double roomArea ( ){
return length * width;
}
}
class RoomCarpet{
RoomDimension rd;
double price;
RoomCarpet ( RoomDimension rd, double price){
this.rd = rd;
this.price = price;
}
public double totalCost( ){
double area = rd.roomArea();
return area * price;
}
}

}
else if(testScore >= 70){
if(classRank >=75){cout<<"Accept";}
else{cout<<"Reject";}
}
else{cout<<"Reject";}
return 0;
}
Explanation:
This declares Score and Rank as string variables
string Score, Rank;
This prompts the user for score and class rank
cout<<"Enter student score and class rank: ";
This gets the user input
cin>>Score>>Rank;
This declarees testScore and classRank as integer; and also initializes them to 0
int testScore = 0, classRank = 0;
The following converts string Score to integer testScore
stringstream sstream(Score);
sstream>>testScore;
The following converts string Rank to integer classRank
stringstream tream(Rank);
tream>>classRank;
The following conditions implement the conditions as given in the question.
If testScore >= 90
if (testScore >= 90){
If classRank >=25
if(classRank >=25){cout<<"Accept";}
If otherwise
