Define a function readList with one parameter, the (string) name of a file to be read from. The file consists of integers, one per line. The function should return a list of the integers in the file.

Answer:

Locality of reference.

Explanation:

In computing, The principle of locality of reference is the probability of a processor to repeatedly access the same set of memory locations within a small time interval. This reference of locality can be spatially based (repetitive usage of data within the same location on the computer memory), or temporally based (repetitive usage of a particular data or resources within a shot time interval). The ability of some computing system to perform this action increases their predictability, and efficiency of memory hierarchy use, among other abilities.

Answer:

The program written in Python is as follows:

See Explanation section for line by line explanation

for n in range(100,1000):

     isum = 0

     for d in range(1,n):

           if n%d == 0:

                 isum += d

     if isum == n * 2:

           print(n)

Explanation:

The program only considers 3 digit numbers. hence the range of n is from 100 to 999

for n in range(100,1000):

This line initializes sum to 0

     isum = 0

This line is an iteration that stands as the divisor

     for d in range(1,n):

This line checks if a number, d can evenly divide n

           if n%d == 0:

If yes, the sum is updated

                 isum += d

This line checks if the current number n is a double-perfect number

     if isum == n * 2:

If yes, n is printed

           print(n)

When the program is run, the displayed output is 120 and 672

Explanation:

The first electric, general-purpose computer, ENIAC, was programmed by flipping switches by hand.

ENIAC is an acronym for Electronic Numerical Integrator and Computer, it was developed in 1945 by John Mauchly and J. Presber Eckert. ENIAC was used for solving numerical problems or calculation-related tasks by the process of reprogramming.

In order to give the ENIAC a series of machine instructions to follow in the execution of a task, the programmers had to undergo the cumbersome procedure of connecting, removing, reconnecting cables and flipping switches by hand because data couldn't be stored in memory.

Explanation:

The DNS server is said to be a caching-only DNS server.

A caching-only Domain Name System server, works by recieving queries from the client, proceeds to perform queries against other named servers, then caches the results and returns the results to the client.

Subsequent queries are resolved and returned for the specified host straight from the the cache, by the server, instead of submitting to the external server.

The advantage of this process is that it reduces traffic from outgoing DNS and speeds up the name resolution. Also, there is a reduction in the amount of query traffic.

Answer:

Here is the function PrintSongsShorterThan() which prints all the songs from the album shorter than the value of the parameter songDuration.

void Album::PrintSongsShorterThan(int songDuration) const {   //function that takes the songDuration as parameter

unsigned int i;  

Song currSong;    //object of Song

cout << "Songs shorter than " << songDuration << " seconds:" << endl;  

for(int i=0; i<albumSongs.size(); i++){    

currSong = albumSongs.at(i);    

if(currSong.GetDuration()<songDuration){    //checks if the song duration of the song from album is less than the value of songDuration

currSong.PrintSong();     } } }  //calls PrintSong method to print all the songs with less than the songDuration

Explanation:  

I will explain the working of the for loop in the above function.

The loop has a variable i that is initialized to 0. The loop continues to execute until the value of i exceeds the albumSongs vector size. The albumSongs is a Song type vector and vector works just like a dynamic array to store sequences.

At each iteration the for loop checks if the value of i is less than the size of albumSongs. If it is true then the statement inside the loop body execute. The at() is a vector function that is used to return a reference to the element at i-th position in the albumSongs.  

So the album song at the i-th index of albumSongs is assigned to the currSong. This currSong works as an instance. Next the if condition checks if that album song's duration is less than the specified value of songDuration. Here the method GetDuration() is used to return the value of duration of the song. If this condition evaluates to true then the printSong method is called using currSong object. The printSong() method has a statement cout << name << " - " << duration << endl; which prints/displays the name of the song with its duration.

If you see the main() function statement:

musicAlbum.PrintSongsShorterThan(210);  

The musicAlbum is the Album object to access the PrintSongsShorterThan(210) The value passed to this method is 210 which means this is the value of the songDuration.

As we know that the parameter of PrintSongsShorterThan method is songDuration. So the duration of each song in albumSongs vector is checked by this function and if the song duration is less than 210 then the name of the song along with its duration is displayed on the output screen.

For example if the album name is Anonymous and the songs name along with their duration are:

ABC 400  

XYZ 123  

CDE 300  

GHI 200  

KLM 100  

Then the above program displays the following output when the user types "quit" after entering the above information.

Anonymous                                                              

Songs shorter than 210 seconds:                                                                         XYZ - 123                                                                                                              

GHI - 200                                                                                                              

KLM - 100  

Notice that the song name ABC and CDE are not displayed because they exceed the songDuration i.e. 210.

Answer:

Here is the Python program:

def input_type(input_string): #function that takes a string as input and returns the type of that string

   try:   #used to test a block of code for input string type              

       if type(eval(input_string)) == float: #if the type of the string is float

           return "float" #function returns float

       elif type(eval(input_string)) == int: #else if the type of the string is int

           return "integer"#function return integers

       elif type(eval(input_string)) == bool:#else if the type of the string is bool

           return "boolean" #function return boolean

   except: #if the type of the string is neither int, bool nor float

       return "string" #function return boolean

#following statements are used to  test the working of the above function

print(input_type(" ")) #prints string

print (input_type ("False")) #prints boolean

print (input_type ("7.432621")) #prints  float

print (input_type("2788"))#prints int

Explanation:

The function input_type() takes a user input and returns the type of that string input the user entered. The user input can be one of the following types:

int which is the data type of an integer for example 1, 2, 3 etc

float which is the data type of a floating point number for example 1.2, 3.4 etc

bool which is the data type of a boolean for example True or False

string that can be characters for example an empty space character " "

try block here is used to generate an exception and it is used to test a block in the code that checks for the type of the user input. The except block here is used to handle that error. This is executed when the try part raises an error.

Inside the try block, the if and elif statements check the type of the string.

if type(eval(input_string)) == float: statement checks if the type of the string is float. Here the eval() method is used to convert the input string because the user input is basically a string value. So this method evaluates the input_string.

type() method is used to return the type of that evaluated user input string. If condition checks if type(eval(input_string)) which is the type of the evaluated input string is equal to float. If this condition evaluates to true then the function returns "float" otherwise it moves to the next elif statement. Similarly the type of the user input is checked for int in elif part and if both these if and elif conditions evaluate to false then the next elif statement is executed that checks the user input to be bool. If all these three if elif statements evaluate to false then the except part executes which returns "string". The program along with its output is attached in a screenshot.

a)

void zero(double big_nums[]);  

b)

zero(big_nums)  

c)

int add1AndSum (int one_small[]);

d)

add1AndSum(one_small);

Explanation:

a)

void zero(double big_nums[]);  

in this statement:

zero is the name of the function

void is used as the function does not return a value.

The function zero takes an array parameter i.e. big_nums[]

big_nums is the name of the array

big_nums[] array has a data type double

b)

zero is the name of the function

In part a) function zero has a parameter which is the array big_nums. So in order to call this function an array has to be passed as a parameter to this function.

So in this statmenent zero(big_nums) the array big_nums is passed to the zero function. You can also declare a new  double type array with a different name in main() function and can pass this to the zero function as:

double array[ ] = { 20.6, 30.8, 5.1};

zero(array);

Look at the following program for the better understanding of part a) and b)

#include <iostream>   //for using input output functions

using namespace std;  //to access objects like cin cout

void zero (double big_nums[]);   // function prototype

int main() {  //start of main() function

double a[ ] = { 20.6, 30.8, 5.1};  // double type array a with elements

zero(a);    }   //calls zero function passing array a to the function

void zero(double big_nums[]){      // function zero with double type array big_nums as parameter and the function returns no value

   int i;    

   for(i=0;i<3;++i)     {

        cout<<big_nums[i];     }  }  //prints the elements of array

c)

add1AndSum is the name of the function

int is used as the function does not return an integer.

The function add1AndSum takes an integer array parameter i.e. one_small[]

one_small is the name of the array

one_small[] array has a data type int

d)

add1AndSum is the name of the function

In part c) function add1AndSum has a parameter which is the array one_small. So in order to call this function an array has to be passed as a parameter to this function.

So in this statement add1AndSum(one_small); the array one_small is passed to the add1AndSum function. You can also declare a new  int type array with a different name in main() function and can pass this to the add1AndSum function.

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

       a = float(input())

       l.append(a)

   return l

def averageCalculator(l):

   total = 0

   for i in l:

       total += i

   avg = total/len(l)

   return avg

def printoutput(avg):

   print("The average of numbers is ", avg)

l = inputNumber()

avg = averageCalculator(l)

printoutput(avg)

Explanation:

A subprogram may be considered as a method where we pass some values in the arguments and return some value.

The answer is written in python language, where we have used

inputNumber() subprogram to get the input from the user.

function averageCalculator() to calculate the average.

printoutput() subprogram to print the output or the average of the numbers.

Please refer to the attached image for better understanding of the indentation of code.

Now, let us learn about them one by one:

inputNumber(): We get the number of values to be entered as an integer value and then get the numbers as float.

Store the values in a list and return the list to the caller main program.

averageCalculator(l): Contains a list as argument as we got from inputNumber(). It sums all the numbers and divides with total number to find the average. Returns the average value to the caller main program.

printoutput(avg): Contains an argument which is the average calculated in the averageCalculator(). It prints the argument passed to it.

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.
