what is the difference between packed and unpacked bcd numbers ​

Answer:

Explanation:

The following code is written in Python. I created a dictionary with all the possible gene combinations and their corresponding amino acids. The user then enters a string. The string is split into triples and checked against the dictionary. If a value exists the gene and amino acid is printed, otherwise an "Invalid Sequence" error is printed for that triple. The program has been tested and the output can be seen in the attached image below.

Answer:

d. ask customers to respond to a brief survey of their attitudes regarding life insurance.

Explanation:

A life insurance policy can be defined as a contract between a policyholder and an insurer, in which the insurer agrees to pay an amount of money to a specific beneficiary either upon the death of the insured person (decedent) or after a set period of time.

A salesperson (sales representative) refers to an individual or employee who is saddled with the responsibility of taking orders from customers, as well as selling finished goods and services to consumers or end users.

A foot-in-the-door phenomenon can be defined as a compliance (persuasive) technique or tactics that assumes a person agreeing to perform a small request increases the likelihood of he or she agreeing to a subsequent larger request. Thus, it posits that when a person agrees to a small, it makes it difficult for him or her to decline a second, larger (bigger) request.

In this context, a life insurance salesperson who takes advantage of the foot-in-the-door phenomenon would most likely ask his or her customers to respond to a brief survey of their attitudes regarding life insurance.

Being over-enthusiastic and crossing the line always get you in trouble even if you’re using the best LinkedIn automation tool in the world.  

When you try to hit the jackpot over the night and send thousands of connection requests in 24 hours, LinkedIn will know you’re using bots or tools and they will block you, temporarily or permanently.    

This is clearly against the rules of LinkedIn. It cracks down against all spammers because spamming is a big ‘NO’ on LinkedIn.    

What people do is that they send thousands of connection requests and that too with the same old spammy templates, “I see we have many common connections, I’d like to add you to my network.”    

It will only create spam.    

The LinkedIn algorithm is very advanced and it can easily detect that you’re using a bot or LinkedIn automation tool and you’ll be called out on it.

Creating users:

We will use the useradd command to achieve this. Using that same command, you can create users who would log in or customers who would log in (in the case of creating a user for a software installation).

In its basic form, the command is as follows:

Take this user olivia, for instance. Assuming that you had been to issue the command prompt:

Users are added to the system without the need for a home directory and are unable to log on. It if we were using this rather than running the command without arguments?

Using the command above, a new user would be created, including a home directory that corresponded to the username. That means that you might now see the name "olivia" in the directory "/home".

But what about the lockout concern that was raised earlier? Both these methods are possible. After creating the user, you can enter the following command:

You'll be requested to enter & verify your new password once you've completed the process. This unlocks the user profile, allowing them to log in.

This command might look like if you wanted to accomplish it in one go:

You should be using Passcodes as the login for the user olivia.

As soon as the user logs in, he or she can update their account password by using the password command to input their current password, and afterward entering/verifying their new one.

To create a user that has no personal account and cannot log in, execute the following instructions:

The user to be added is identified by USERNAME.

It establishes a user with really no root folder and prevents them from signing in with a second operation.

To add an existing user to a group on Linux, follow the instructions:

Answer:

The program in Python is as follows:

cents = int(input("Cents: "))

qtr = int(cents/25)

cents = cents - qtr * 25

dms = int(cents/10)

cents = cents - dms * 10

nkl = int(cents/5)

pny = cents - nkl * 5

print("Pennies: ",pny)

print("Nickels: ",nkl)

print("Dimes: ",dms)

print("Quarters: ",qtr)

Explanation:

The program in Python is as follows:

cents = int(input("Cents: "))

This calculate the number of quarters

qtr = int(cents/25)

This gets the remaining cents

cents = cents - qtr * 25

This calculates the number of dimes

dms = int(cents/10)

This gets the remaining cents

cents = cents - dms * 10

This calculates the number of nickels

nkl = int(cents/5)

This calculates the number of pennies

pny = cents - nkl * 5

The next 4 lines print the required output

print("Pennies: ",pny)

print("Nickels: ",nkl)

print("Dimes: ",dms)

print("Quarters: ",qtr)

The packets would be encapsulated in single frame in scenario A. In scenario B, it should be in multi frames.

In scenario A, given that this network has been said to be prone to error, the packets should be encapsulated in single frames.

The reason for this is because, using a single frame helps to decrease error. We have been told already that it is prone to error. If you use the multi frame, there would be very high likelihood of errors occurring.

In scenario B, given that the network is accurate and very reliable, the best packet is the multi frame.

It would give a quicker transmission and the likelihood of errors occurring is also low.

Answer:

When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.

Program using linear recursion to duplicate items in a list:

def duplicate_list(lst):

   if not lst:

       return []

   else:

       return [lst[0], lst[0]] + duplicate_list(lst[1:])

# Example usage

user_input = input("Enter a list of items: ").split()

original_list = [item for item in user_input]

duplicated_list = duplicate_list(original_list)

print("Duplicated list:", duplicated_list)

By implementing a function that utilizes linear recursion, we can create a copy of an original list with duplicated items. The function duplicate_list takes a list lst as input and checks if it is empty. If the list is empty, it returns an empty list as the base case.

Otherwise, it combines the first item of the list with itself and recursively calls the function with the remaining items (lst[1:]). The duplicated items are added to the resulting list. This process continues until all items in the original list have been duplicated and the duplicated list is returned.

The program is as follows:

#include <iostream>

#include <string>

using namespace std;

class Student{

string studName, indexNo, remarks; int marks;  char grade;

public:

 void getData(){

     cin.ignore();

     cout<<"ID: "; getline(cin,indexNo);

  cout<<"Name:"; getline(cin,studName);

  cout<<"Marks: ";cin>>marks;  }

 void calculate(){

  if(marks>=70 && marks<=100){

      remarks ="Excellent";       grade = 'A';   }

  else if(marks>=60 && marks<=69){

      remarks ="Very Good";       grade = 'B';   }

  else if(marks>=50 && marks<=59){

      remarks ="Pass";       grade = 'D';   }

  else{

      remarks ="Fail";       grade = 'F';   }

  cout << "Grade : " << grade << endl;

  cout << "Remark : " << remarks << endl;  }

};

int main(){

int numStudents;

cout<<"Number of students: "; cin>>numStudents;

Student students[numStudents];

for( int i=0; i<numStudents; i++ ) {

 cout << "Student " << i + 1 << endl;

 students[i].getData();

 students[i].calculate(); }

return 0;}

Explanation:

This defines the student class

class Student{

This declares all variables

string studName, indexNo, remarks; int marks;  char grade;

This declares function getData()

public:

 void getData(){

     cin.ignore();

Prompt and get input for indexNo

     cout<<"ID: "; getline(cin,indexNo);

Prompt and get input for studName

  cout<<"Name:"; getline(cin,studName);

Prompt and get input for marks

  cout<<"Marks: ";cin>>marks;  }

This declares funcion calculate()

 void calculate(){

The following if conditions determine the remark and grade, respectively

  if(marks>=70 && marks<=100){

      remarks ="Excellent";       grade = 'A';   }

  else if(marks>=60 && marks<=69){

      remarks ="Very Good";       grade = 'B';   }

  else if(marks>=50 && marks<=59){

      remarks ="Pass";       grade = 'D';   }

  else{

      remarks ="Fail";       grade = 'F';   }

This prints the grade

  cout << "Grade : " << grade << endl;

This prints the remark

  cout << "Remark : " << remarks << endl;  }

};

The main begins here

int main(){

This declares number of students as integer

int numStudents;

Prompt and get input for number of students

cout<<"Number of students: "; cin>>numStudents;

This calls the student object to declare array students

Student students[numStudents];

This is repeated for all students

for( int i=0; i<numStudents; i++ ) {

Print number

 cout << "Student " << i + 1 << endl;

Call function to get data

 students[i].getData();

Call function to calculate

 students[i].calculate(); }

Explanation:

Excel will generally be able to handle any properly-input mathematical formula, if valid operators are used. Commonly used operators include "+" (addition), "-" (subtraction), "*" (multiplication) and "/" (division).  (Microsoft has a complete list of valid operators to be used in Excel formulas on the Office website).  Here are some examples of formulas using common operators:

Formula                                                                              Description

=C2-B2                                                                Subtracts contents of B2 from contents of C2

=C2/B2                                                                Divides contents of C2 by contents of B2

=(B2+C2+D2)/3                                                  Adds contents of B2, C2, and D2 and divides result by 3

After hitting "Enter", the cell will display the calculated value, while the formula bar will still display the formula.  (Note: Always hit “Enter” when finished entering a formula, manually.  If you click off the cell, the cell you click to will be added to your formula.)Formulas

Formulas in Excel are basically mathematical expressions that use cell references (e.g., “A5”,” D17”) as arguments.  For example, a formula that adds the contents of cell E5 and E6 could be written as follows:

= E5+E6

(Note: all formulas in Excel need to be preceded by an “=” sign.) If the values contained in E5 and E6 are 6 and 11, respectively, the formula will produce 17 as the value it displays. If you change E5 to 7, the result will automatically change to 18.

Example

Let's say you were putting together an office supply order, and you wanted to keep track of much you were spending. You could put together a spreadsheet like the one below, with the list of items to be purchased, their unit prices, the number of each item ordered, and the total spent for each.  It would make sense to enter the things you know in advance (like the price of individual items and the number ordered), but you could let Excel calculate the totals for you.  For the first item listed below (pencils), this could be done by making the value of the total price (cell D2), the value of the unit price (held in cell C2) multiplied by the number of items ordered (held in D2).  This formula would be written "=B2*C2".

Once you click "OK", your completed formula will be input into the cell.

Copying and pasting formulas

Often, you will need Excel to do a series of similar computations, where the only things that will change are the cells used as arguments.  For instance, in the example above, you would probably like Excel to calculate the Total Price for each item in the order.  You could re-input the same formula used to get the total price for pencils in each cell in that row, just changing the cells referenced (i.e. "=PRODUCT(B3:C3)", "=PRODUCT(B4:C4)", etc.), but Excel has simpler method for this. If you have multiple cells in the same row or column that need to do the same computation, you can simply copy the value in the cell you entered a formula, and then paste it into the subsequent cells.  Excel will then automatically adjust which cells are included in the formula, based upon which cell the formula was pasted to.  So, if the original formula entered in D2 was "=PRODUCT(B2:C2)", the formula pasted into D4 would be "=PRODUCT(B4:C4)"

More simply, if you have a formula you want repeated in a number of directly adjoining cells, you can just click and drag the bottom right corner of the cell with the original formula (see image below) onto the cells you want the same formula entered, and Excel will automatically copy and paste the formula for you, with appropriate adjustments made to the cell numbers in the formula.

After selecting "PRODUCT" and clicking OK, you will get another dialog box, that allows you to select the cells to be multiplied.  You can do this for individual cells, by selecting cells separately in the "Number1" and  "Number2" boxes shown below, or by selecting an array of cells, by clicking and dragging on the range cells you want to use on the spreadsheet, itself.  (Note: if you try to enter a formula in a cell using the Insert Formula button and there are adjacent cells with numbers, Excel will often select those cells automatically, so make sure the cells selected in the dialog box are the correct ones.) Excel also has built-in functions that can do a lot of useful calculations.  These are most easily accessed by hitting the Insert Function button, which is represented by the “fx” symbol next to the formula bar.  For example, instead of entering the formula shown above, the same result could have been achieved using the built-in "PRODUCT" function by clicking in cell D2 and hitting the Insert Formula button.  This would give a dialog box like the one shown, below.

After choosing “PRODUCT” and pressing OK, a new dialogue box will appear where you may choose which cells should be multiplied. By selecting particular cells in the “Number1” and “Number2” boxes as shown below, you can do this for specific cells.

Additionally, Excel contains many useful built-in functions that can perform calculations. The button shown by the “fx” sign next to the formula bar, “Insert Function,” can be used to access these the simplest way by clicking it.

Make sure the cells selected in the dialogue box are the proper ones because if you try to insert a formula in a cell using the Insert Formula button and there are adjacent cells containing numbers. Excel will frequently select those cells automatically.)

Therefore, by deciding a range of cells on the spreadsheet itself by clicking and dragging on the desired range of cells.
