You are asked to write an app to keep track of a relatively small music library. The app should load song information from a data file once the app is started. It should allow user to view, add, remove, and search for songs. The app should save the data back to the same data file when the program exits.

Explanation:

Packed BCD ( Binary coded decimal) is type in which each decimal digit is represented by 4 bits ( 1 nibble) . For Example : 14 will be shown as 0001 0100 in packed BCD form. Unpacked BCD is type in which each decimal digit is represented by 8 bits ( 1 byte).

Answer:

import csv

import sys

file_csv = argv

with open( "file_csv", "rb" ) as file:

      rowlist= csv.DictReader( file )

      dict_count={ }

      for row in rowlist:

           dict_count[ row[ 'department' ] ] = dict_count.get( row[ 'department' ], 0 ) + 1

      print( " The count of employees per department are", dict_count )

Explanation:

The python script in the solution above is able to accept user input csv files via command prompt and get an output of the number of employees for each department.

Answer:

Hash function have less collision than a internet checksum because of computational infeasibility.

Explanation:

A collision means there is more then one way to produce the same sum. It is nearly difficult to developed two messages with same hash however, in checksum, it is more easier to develop or modify two messages to have same sum, thereby enabling attackers to have access to the message or the information arising to less message integrity.

For option a:

The baseline register is [tex]\bold{BX}[/tex], while the index register is [tex]\bold{CX+5*AX}[/tex].

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

Answer:

def convert_to_string(nums):

   for i in range(len(nums)):

       nums[i] = str(nums[i])

nums = [7, 28, 92]

print(nums)

convert_to_string(nums)

print(nums)

Explanation:

Create a function called convert_to_string that takes one parameter, nums

Create a for loop that iterates through the nums. Inside the loop, set each item to its string equivalent using type casting (str)

Initialize a list

Print the list before the function call

Call the function, passing the list as a parameter

Then, print the list again to see the difference

Answer:

D. all of the above

Explanation:

A Stored Procedure (sp) is an already compiled group of SQL requests that contains either one or more statements which are stored in the master database.

A Stored Procedure can be created by using the CREATE PROC statement.

They perform standard tasks, stored in the master database and can change with each new version of SQL, so option D is correct.

Answer:

The answer is "check the worksheet is not read only"

Explanation:

The read only mode is used for read the file data, and it doesn't allows the user to update the file, and for updating the worksheet we should check iut does not open in the read-only mode.

If it is open, then we close it and for close we goto the office button and click on the tools option after that goto general setting, in this there is a check box for turn off the read-only mode.

Answer:

The file can be read only by a user with the decryption key

Explanation:

The way encryption works is it scrambles the data in a file following the rules of the encryption algorithm using a certain key to tell it how to scramble everything.

Without the key, the computer doesn't know how to decrypt it.

This is true no matter who has access to the file, be it a system administrator, a hacker, or even a legitimate user who has somehow lost access to the key

Strictly speaking, encryption can be broken, but, especially with modern encryption, that's a matter of centuries, and isn't really feasible

The statement that is true of an encrypted file is that The file can be read only by a user with the decryption key.

A decryption key is known to be a key that is given to Customers by a specific Distributor.

This key allows Customers to open and access the Software that they bought. The decryption key is a  mechanism that  permit  that a file can be read only by a user.

Answer:

The programming language is not stated; However, the program written in C++ is as follows: (See Attachment)

#include<iostream>

using namespace std;

string capt(string result)

{

result[0] = toupper(result[0]);

for(int i =0;i<result.length();i++){

 if(result[i]=='.' || result[i]=='?' ||result[i]=='!')  {

 if(result[i+1]==' ') {

  result[i+2] = toupper(result[i+2]);

 }

 if(result[i+2]==' ')  {

  result[i+3] = toupper(result[i+3]);

 }

 } }

return result;

}

int main(){

string sentence;

getline(cin,sentence);

cout<<capt(sentence);

return 0;

}

Explanation:

The method to capitalize first letters of string starts here

string capt(string result){

This line capitalizes the first letter of the sentence

result[0] = toupper(result[0]);

This iteration iterates through each letter of the input sentence

for(int i =0;i<result.length();i++){

This checks if the current character is a period (.), a question mark (?) or an exclamation mark (!)

if(result[i]=='.' || result[i]=='?' ||result[i]=='!')  {

 if(result[i+1]==' '){  ->This condition checks if the sentence is single spaced

  result[i+2] = toupper(result[i+2]);

-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized

 }

 if(result[i+2]==' '){ ->This condition checks if the sentence is double spaced

  result[i+3] = toupper(result[i+3]);

-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized

 }

}

}  The iteration ends here

return result;  ->The new string is returned here.

}

The main method starts here

int main(){

This declares a string variable named sentence

string sentence;

This gets the user input

getline(cin,sentence);

This passes the input string to the method defined above

cout<<capt(sentence);

return 0;

Automatic Private IP Addressing (APIPA) is a Windows based operating systems feature that allows a computer to assign itself automatically to an IP address even though there is DHCP server to perform the function.

From the information that has been provided in the question, we can see that the type of address that is used is APIPA.

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;

}
