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.

(a) Extend code snippet 1 to check for read and write access permissions of a given file
(b) Write a C program where open system call creates a new file (say, destination.txt) and then opens it. (Hint: use the bitwise OR flag)
1. UNIX cat command has three functions with regard to text files: displaying them, combining copies of them and creating new ones.
Write a C program to implement a command called displaycontent that takes a (text) file name as argument and display its contents. Report an appropriate message if the file does not exist or can’t be opened (i.e. the file doesn’t have read permission). You are to use open(), read(), write() and close() system calls.
NOTE: Name your executable file as displaycontent and execute your program as ./displaycontent file_name
2. The cp command copies the source file specified by the SourceFile parameter to the destination file specified by the DestinationFile parameter.
Write a C program that mimics the cp command using open() system call to open source.txt file in read-only mode and copy the contents of it to destination.txt using read() and write() system calls.
3. Repeat part 2 (by writing a new C program) as per the following procedure:
(a) Read the next 100 characters from source.txt, and among characters read, replace each character ’1’ with character ’A’ and all characters are then written in destination.txt
(b) Write characters "XYZ" into file destination.txt
(c) Repeat the previous steps until the end of file source.txt. The last read step may not have 100 characters.

Suppose you have a string matching algorithm that can take in (linear)strings S and T and determine if S is a substring (contiguous) of T. However,you want to use it in the situation where S is a linear string but T is a circularstring, so it has no beginning or ending position. You could break T at eachcharacter and solve the linear matching problem|T|times, but that wouldbe very inefficient. Show how to solve the problem by only one use of thestring matching algorithm.

Write a user input program that simulates a game of a rolling pair of dice. You can create/simulate rolling one die by choosing one of the integers values of 1, 2, 3, 4, 5, or 6 at randomly. The number that the user chooses will represents the number on the dice after it is rolled. As a hint use Math.random Which will perform the computation to select a random integer between 1 and 6. Assign the value to a variable to represent one of the dice that are being rolled. Perform this operation twice then you will add the results in order to obtain the total roll. Your program should output the number showing on each dice as well as the total roll. For example:
Answer:
Follows are the program to this question:
public class Main//defining a class
{
public static void main(String[] bax)//main method
{
int d1,d2,r; //defining integer variables
d1 = (int)(Math.random()*6) + 1;//defining d1 variables that use random method to store a random value
d2 = (int)(Math.random()*6) + 1;//defining d2 variables that use random method to store a random value
r= d1 + d2;//defining r variable that adds d1 and d2 values
System.out.println("On the first time die will gives: " + d1);//print values with the message
System.out.println("On the second time die will gives: " + d2);//print values with the message
System.out.println("The total roll value is: " + r);//print values with the message
}
}
Output:
On the first time die will gives: 6
On the second time die will gives: 1
The total roll value is: 7
Explanation:
In this code three integer variable "d1,d2, and r" is declared, in which the "d1 and d2" variable is used, that uses the random method to hold a random value from 1 to 6 in its variable.
In the next step "r" variable is declared that calculates the addition of the "d1 and d2", and at the last, it uses the print method to print value with the message.
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

HTML, the markup language of the web, specifies colors using the RGB model. It uses a two-digit hexadecimal (that is, base 16) representation for each component of the vector, and concatenates the three numbers together to form one large, six-digit number. For instance, the HTML color code #80FF3B has red component 80, green component FF, and blue component 3B. In hexadecimal, the digits 0 through 9 have their usual meanings, but the letters A through F also function as digits, and have the meanings 10 through 15, respectively. Because hexadecimal means base 16, a two-digit number such as 3B thus has the meaning 16⋅3+11=59. The 16 is used because the 3 is in the 16s place, and the 11 is the meaning of the digit B. (If you found this introduction to hexadecimal notation too brief, consult the web for more details.) What is the maximum number representable with two hexadecimal digits?
Solution :
It is given that :
The digits 0 through 9 in hexadecimal have their usual meanings. But letters A through F function like the digits and it means digits 10 through 15, respectively.
Now the base of a hexadecimal is 16.
Now we know from 0 to 9 [tex]$\rightarrow$[/tex] A, B, C, D, E, F
Now the maximum two digits hexadecimal numbers are = F F
So, F F [tex]$= 16 \times 15 + 16^0 \times 15$[/tex]

Write two alternate functions specified below, each of which simply triples the variable count defined in main. These two functions are: a. Function tripleByValue that passes a copy of count by value, triples the copy and returns the new value.b. Function tripleByReference that passes count by reference via a reference parameter and triples the original value of count through its alias(i.e. the reference parameter)For example, if count
Answer:
Following are the code to this question:
#include <iostream>//header file
using namespace std;
int triplebyValue(int count)//defining a method triplebyValue
{
int x=count*3;//defining a variable x that multiply by 3 in the count
return x;//return value of x
}
void triplebyReference(int& count)//defining a method triplebyReference that hold count variable as a reference in parameter
{
count*=3;//multipling a value 3 in the count variable
}
int main()//main method
{
int count;//defining integer variable
count=triplebyValue(3);//use count to call triplebyValue method
cout<<"After call by value, count= "<<count<<endl;//print count value with message
triplebyReference(count);//calling a method triplebyReference
cout<<"After call by reference, count= "<<count<<endl;//print count value with message
return 0;
}
Output:
After call by value, count= 9
After call by reference, count= 27
Explanation:
In this code two methods "triplebyValue and triplebyReference" are declared, which accepts a count variable as a parameter, and in both multiply the count value by 3 and return its value.
Inside the main method, an integer variable "count" is declared that first calls the "triplebyValue" method and holds its value into count variable and in the next, the method value is a pass in another method that is "triplebyReference", and use print method to print both methods value with a message.
