Emerging technology is a term given to the development of new technologies or improvement on existing technologies that are expected to be available in the nearest future.

Examples of emerging technologies includes but not limited to block chain, internet of things, robotics, cognitive science, artificial intelligence (AI) etc.

One of the reasons that makes emerging technology happen is the quest to improving on existing knowledge. People want to further advance their knowledge in terms of coming up with newest technologies that would make task faster and better and also address human issues. For instance, manufacturing companies make use of robotics,design, construction, and machines(robots) that perform simple repetitive tasks which ordinarily should be done by humans.

Other reasons that makes emerging technology happens are economic benefit, consumer demand and human needs, social betterment, the global community and response to social problems.

Impact that emerging technology will have on;

• Individuals. The positive effect of emerging technology is that it will create more free time for individuals in a family. Individuals can now stay connected, capture memories, access information through internet of things.

• Society. Emerging technology will enable people to have access to modern day health care services that would prevent, operate, train and improving medical conditions of people in the society.

• Environment. Before now, there have been global complains on pollution especially on vehicles and emission from industries. However, emerging technology will be addressing this negative impact of pollution from vehicles as cars that are currently being produced does not use petrol which causes pollution.

what makes ''emerging technologies'' happen is the necessity for it, the need for it in the society.

The impact they will have on individuals ,society,and environment is that it will improve areas of life such as communication, Transportation, Agriculture.

Emerging technologies can be regarded as the technologies in which their development as will as practical applications are not yet realized.

The visible variables with the name of the function in which it was defined are given below.

Explanation:

In main() function three integer type variables are declared: a,b,c

In fun1() three int type variables are declared/defined: b,c,d

In fun2() three int type variables are declared/defined: c,d,e

In fun3() three int type variables are declared/defined: d,e,f

a. Main calls fun1; fun1 calls fun2; fun2 calls fun3

Visible Variable:  b, c, d        Defined in: fun1

Visible Variable:  e, f             Defined in: fun3 ( d not visible)

Visible Variable:  a                Defined in: main ( b and c not visible)

Here variables c, d and e of fun2 are not visible

d. Main calls fun3; fun3 calls fun1

Here the main() calls fun3, fun3 calls fun1. This means the body of fun1 executes first, then of fun3 and then in last, of main()

Visible Variable: b, c, d     Defined in: fun1  

Visible Variable:   e, f        Defined in:  fun3   ( d not visible )

b. Both incremental and iterative development.

Explanation:

Agile software development is based on both incremental and iterative development. It is an iterative method to software delivery in which at the start of a project, software are built incrementally rather than completing and delivering them at once as they near completion.

Incremental development means that various components of the system are developed at different rates and are joined together upon confirmation of completion, while Iterative development means that the team intends to check again components that makes the system with a view to revising and improving on them for optimal performance.

Agile as an approach to software development lay emphasis on incremental delivery(developing system parts at different time), team work, continuous planning and learning, hence encourages rapid and flexible response to change.

Answer:

The program written in C++ is as follows; (See Explanation Section for explanation)

#include <iostream>

using namespace std;

void revstring(string word)

{

   string  stringreverse = "";

   for(int i = word.length() - 1; i>=0; i--)

 {

     stringreverse+=word[i];

 }

 cout<<stringreverse;

}

int main()

{

 string user_input;

 cout << "Enter a string:  ";

 getline (std::cin, user_input);

 getstring(user_input);

 return 0;

}

Explanation:

The method starts here

void getstring(string word)

{

This line initializes a string variable to an empty string

   string  stringreverse = "";

This iteration iterates through the character of the user input from the last to the first

   for(int i = word.length() - 1; i>=0; i--)   {

     stringreverse+=word[i];

 }

This line prints the reversed string

 cout<<stringreverse;

}

The main method starts here

int main()

{

This line declares a string variable for user input

 string user_input;

This line prompts the user for input

 cout << "Enter a string:  ";

This line gets user input

 getline (std::cin, user_input);

This line passes the input string to the method

 revstring(user_input);

 return 0;

}

Answer:

I am writing a Python program:

pi=3.14 #the value of pi is set to 3.14

radius = float(input("Enter the radius of sphere: ")) #prompts user to enter the radius of sphere

surface_area = 4 * pi * radius **2 #computes surface area of sphere

volume = (4.0/3.0) * (pi * radius ** 3) #computes volume of sphere

print("Surface Area of sphere is: ", surface_area) #prints the surface area

print("Volume of sphere is: {:.2f}".format(volume)) #prints the volume        

Explanation:

Please see the attachment for the complete interactive code.

The first three lines of print statement in the attached image give a brief description of the program.

Next the program assigns 3.14 as the value of π (pi). Then the program prompts the user to enter the radius. Then it computes the surface area and volume of sphere using the formulas. Then it prints the resultant values of surface area and volume on output screen.

The psuedocode for this program is given below:

PROGRAM SphereVolume

pi=3.14

NUMBER radius, surface_area, volume  

INPUT radius

COMPUTE volume = (4/3) * pi* radius ^3

COMPUTE surface_area = 4 * pi * radius ^ 2

OUTPUT volume , surface_area

END

Answer:

A) Number of bits for byte = 6 bits

B) number of bits for index = 17 bits

C) number of bits for tag = 15 bits

Explanation:

Given data :

cache size = 64 kB

block size = 32 -byte

block address = 32 -bit

number of blocks in cache memory  

cache size / block size = 64 kb / 32 b = 2^11 hence the number of blocks in cache memory = 11 bits = block offset

A) Number of bits for byte

[tex]log _{2} (6)^2[/tex] = 6  bits

B) number of bits for index

block offset + byte number

= 11 + 6 = 17 bits

c ) number of bits for tag

= 32 - number of bits for index

= 32 - 17 = 15 bits

Here is the JAVA program:

import java.io.*;

import java.util.*;

public class Main {

public static void main(String[] args) throws FileNotFoundException{ //the start of main() function body, it throws an exception that indicates a failed  attempt to open the file

Scanner input = new Scanner(new File("file.txt")); //creates a Scanner object and a File object to open and scan through the file.txt    

coinFlip(input);    } //calls coinFlip method

public static void coinFlip(Scanner input) { //coinFlip method that accepts as its parameter a string input holding a file name

while(input.hasNextLine()) { //iterates through the input file checking if there is another line in the input file

Scanner scan = new Scanner(input.nextLine()); //creates a Scanner object

int head = 0; // stores count of number of heads

int count = 0; //stores count of  total number of tokens

while(scan.hasNext()) { //iterates through the sequence checking if there is another sequence in the input file

String token= scan.next(); // checks and returns the next token

if (token.equalsIgnoreCase("H")||token.equalsIgnoreCase("Heads")) { //compares H or Heads with the tokens in file ignoring lower case and upper case differences

           head++;                } //if a token i.e. any form of heads in file matches with the H or Heads then add 1 to the number of heads

           count++;            } //increment to 1 to compute total number of counts

double result = Percentage(head, count); //calls Percentage method passing number of heads and total counts to compute the percentage of heads

System.out.println(head + " heads " + "(" + result +"%)"); // prints the number of heads

if(result >= 50.00) { //if the percentage is greater or equal to 50

System.out.println("You win!");} //displays this message if above if condition is true

else //if the percentage is less than 50

{System.out.println("You lose!");}  }    } //displays this message if above if condition is false

public static double Percentage(int h, int total) { //method to compute the percentage of heads

double p = (double)h/total* 100; // divide number of heads with the total count and multiply the result by 100 to compute percentage

return p;    } } //returns result

Explanation:

The program is well explained in the comments mentioned with each line of the above code. I will explain how the method coinFlip  works.

Method coinFlip accepts a string holding a file name as its parameter. It opens that file and reads its contents as a sequence of tokens. Then it reads and scans through each token and the if condition statement:

if (token.equalsIgnoreCase("H")||token.equalsIgnoreCase("Heads"))

checks if the each token in the sequence stored in the file is equal to the H or Heads regardless of the case of the token. For example if the first token in the sequence is H then this if condition evaluates to true. Then the head++ statement increments the count of head by 1. After scanning each token in the sequence the variable count is also increased to 1.

If the token of the sequence is HeAds then this if condition evaluates to true because the lower or upper case difference is ignored due to equalsIgnoreCase method. Each time a head is found in the sequence the variable head is incremented to 1.

However if the token in the sequence is Tails then this if condition evaluates to false. Then the value of head variable is not incremented to 1. Next the count variable is incremented to 1 because this variable value is always incremented to 1 each time a token is scanned because count returns the total number of tokens and head returns total number of heads in the tokens.

Percentage method is used to return the percentage of the number of heads in the sequence. It takes head and count as parameters (h and total). Computes the percentage by this formula h/total* 100. If the result of this is greater than or equal to 50 then the message  You win is displayed otherwise message You lose! is displayed in output.

num_owls_A = int(input())

num_owls_B = int(input())

total_owls = num_owls_A + num_owls_B

print("Number of owls:", total_owls)

Explanation:

Initialize the  total_owls as 0

Ask the user to enter num_owls_A and num_owls_B, convert the input to int

Sum the num_owls_A and num_owls_B and set it to the total_owls

Print the total_owls

avg_owls=0.0

num_owls_zooA = int(input())

num_owls_zooB = int(input())

num_owls_zooC = int(input())

num_zoos = 3

avg_owls = (num_owls_zooA + num_owls_zooB + num_owls_zooC) / num_zoos

print('Average owls per zoo:', int(avg_owls))

There is a problem while you are trying the calculate the average owls per zoo.

As you may know, in order to calculate the average, you need to get the total number of owls in all the zoos, then divide it to the number of zoos. That is why you need to sum num_owls_zooA + num_owls_zooB + num_owls_zooC and divide the result by num_zoos

Be aware that the average is printed as integer value. That is why you need to cast the avg_owls to an int as int(avg_owls)
