Data members and member functions jointly determine the characteristics and actions of the objects in a Class. Data members are the variables that make up the data, and member functions are the methods used to modify these variables.
What are the data member in a program?Members declared using any of the basic kinds as well as other types, such as pointer, reference, array types, bit fields, and user-defined types, are referred to as data members.
Any class may contain however many data members are necessary. The only situation in which a limitation might occur is when there is not enough memory.
Member data — information about the thing. Member functions — behavior-related aspects of the object-related functions A class is an object's blueprint. A class is a user-defined type that specifies the appearance of a certain type of object.
Therefore, radius, cylinder, print would be a data member.

Write a program using a dictionary that reads in a single positive digit number [0 - 9] from the user at the keyboard. Your program will then be able to look up the digit key in the dictionary and print the digit value spelled out. If the user types in a number that is either more than one digit, negative, or a non int value, re-prompt the user for valid input. First, before demonstrating your test cases, print out a display copy of the key:value pairs in your dictionary in sorted order. Deliverable: yournameLab4.py Your source code solution and a copy of the run pasted into your source submission file. Be sure to comment out your run so that your .py file will still run in the grader test bed. Validate user input is a single positive digit [0 - 9].
Answer:
The program in Python is as follows:
dict = {0:"Zero",1:"One",2:"Two",3:"Three",4:"Four",5:"Five",6:"Six",7:"Seven",8:"Eight",9:"Nine"}
num = input("Number: ")
while(num.isdigit() == False or int(num)<0 or int(num)>9):
num = input("Number: ")
print(dict)
print(dict[int(num)])
Explanation:
#This initializes the dictionary
dict = {0:"Zero",1:"One",2:"Two",3:"Three",4:"Four",5:"Five",6:"Six",7:"Seven",8:"Eight",9:"Nine"}
#This gets input from the user
num = input("Number: ")
#This loop is repeated until the user enters a valid input
while(num.isdigit() == False or int(num)<0 or int(num)>9):
num = input("Number: ")
#This prints the dictionary
print(dict)
#This prints the value of the key
print(dict[int(num)])

In cell K8, create a formula using the SUM function that calculates the total of range D17:D20 and subtracts it from the value in J8
Answer:
=(J8 - SUM(D17:D20))
Explanation:
Required
Add D17 to D20
Subtract the result from J8
Save the result in K8
To do this, we make use of a nested bracket.
The innermost bracket is to add up D17 To D20 using the sum function.
i.e. SUM(D17:D20)
While the outermost bracket will subtract the calculated sum from J8.
=(J8 - SUM(D17:D20))
The SUM function is used to Adds values, in which users can add different values, in cells or range references or a mix of each of them, and the further calculation can be defined as follows:
In this question, we use the "=(J8 - SUM(D17:D20))" function that's description can be defined as follows:
D17 to D20 AddSubtract the J8 resultSave K8 resultsWe use a nested bracket to do this.D17-D20 is added to the innermost bracket with the sum function.SUM, i.e. (D17:D20)The calculated amount from J8 is taken from the outermost bracket.Therefore the final answer is "=(J8 - SUM(D17:D20))".

Answer:
Server Manager
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM, Windows Server 2008, Windows Server 2009, etc.
Windows Server 2008 is a Microsoft Windows Server operating system and released to the general public on the 27th of February, 2008, as part of the Windows NT family.
Server Manager is a tool that was first introduced in Windows Server 2008 (OS) but remains in Windows Server 2019 (OS). It was designed and developed by Microsoft to provide end users with one location to set up, deploy, and manage servers and server roles.
On the 14th of January, 2020, Microsoft stopped providing online technical content update, free support options, non-security and free security updates on-premises for Windows Server 2008 and Windows Server 2008 R2, as they have reached the end of their support lifecycle.

Write a function, named FileLineCount(), that returns an integer and accepts a string. Pass the function the file name. It should then use a while loop to return the number of lines in a file. Hint: The function will be reading the file you just created above. g
Answer:
Explanation:
The following code is written in Python. It is a function that accepts a file string and uses that string to read the file in that location. Then it uses a while loop that keeps going until there are no more lines in the file. Each iteration it adds 1 to the count variables. Finally, it prints the count variable which contains the total number of lines in the file. The code has been tested and the output can be seen in the attached image below.
def countLines(file):
file = open(file, 'r')
count = 0
while file.readline():
count += 1
print(str(count) + " total lines")
Create a function in Python called HalfList that will accept a list of integers and find the total for the first half of the list. The function needs to return the total or the sum of all these numbers.

2.13 LAB: Branches: Leap Year
A year in the modern Gregorian Calendar consists of 365 days. In reality the earth takes longer to rotate around the sun. To account for the
difference in time every 4 years a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The
requirements for a given year to be a leap year are:
1) The year must be divisible by 4
2) If the year is a century year (1700 1800. etc.), the year must be evenly divisible by 400
Some example leap years are 600712 and 2016
Wirte a program that takes n a year and determines whether that year is a leap year.
Exif the inputs
1712
Answer:
The program in Python is as follows:
year = int(input("Enter a year: "))
print(year,end=" ")
if year % 4 == 0:
if year % 100 == 0:
if year % 400 == 0: print("is a leap year")
else: print("is not a leap year")
else: print("is a leap year")
else: print("is not a leap year")
Explanation:
This gets input for year
year = int(input("Enter a year: "))
This prints year, followed by a blank
print(year,end=" ")
If year is divisible by 4
if year % 4 == 0:
If yes, check if year is divisible by 100
if year % 100 == 0:
If yes, check if year is divisible by 400; print leap year if true
if year % 400 == 0: print("is a leap year")
print not leap year if year is not divisible by 400
else: print("is not a leap year")
print leap year if year is not divisible by 100
else: print("is a leap year")
print leap year if year is not divisible by 4
else: print("is not a leap year")
Answer:
def is_leap_year(user_year):
if(user_year % 400 == 0):
return True
elif user_year % 100 == 0:
return False
elif user_year%4 == 0:
return True
else:
return False
if __name__ == '__main__':
user_year = int(input())
if is_leap_year(user_year):
print(user_year, "is a leap year.")
else:
print(user_year, "is not a leap year.")

Argue your points as to wether i.c.t tools in Africa is harmful or helpful to students
Answer: It is helpful.
Explanation:
Access to more information.
ICT tools such as computers and laptops are able to connect to the internet which has a lot more information on most subjects than a student can find in school.
ICT tools will therefore broaden the information base for African students to enable them acquire more knowledge that could aid the continent in catching up to the west.
Skills acquisition.
The world is increasing moving online and this means that those capable of designing online tools and services will be very successful. This is why Jeff Bezos is so rich.
ICT tools in Africa will enable the students learn about these things from a younger age so that they would be able to launch their own online services for the benefit of the continent and the world.
Making schooling more accessible.
For a long time, there has been a shortage of teachers and schools in certain parts of Africa which has led to a lot of children going without education.
Like the Coronavirus pandemic showed us, with ICT tools, a teacher would be able to reach students that are far from them thereby increasing the number of children who can be educated in Africa even with a shortage of teachers and schools.

IN C++
A. Create an abstract base class called Currency with two integer attributes, both of which are non-public. The int attributes will represent whole part (or currency note value) and fractional part (or currency coin value) such that 100 fractional parts equals 1 whole part.
B. Create one derived class - Money - with two additional non-public string attributes which will contain the name of the currency note (Dollar) and currency coin (Cent) respectively. DO NOT add these attributes to the base Currency class.
C. In your base Currency class, add public class (C++ students are allowed to use friend methods as long as a corresponding class method is defined as well) methods for the following, where appropriate:
Default Construction (i.e. no parameters passed)
Construction based on parameters for all attributes - create logical objects only, i.e. no negative value objects allowed
Copy Constructor and/or Assignment, as applicable to your programming language of choice
Destructor, as applicable to your programming language of choice
Setters and Getters for all attributes
Adding two objects of the same currency
Subtracting one object from another object of the same currency - the result should be logical, i.e. negative results are not allowed
Comparing two objects of the same currency for equality/inequality
Comparing two objects of the same currency to identify which object is larger or smaller
Print method to print details of a currency object
All of the above should be instance methods and not static.
The add and subtract as specified should manipulate the object on which they are invoked. It is allowed to have overloaded methods that create ane return new objects.
D. In your derived Money class, add new methods or override inherited methods as necessary, taking care that code should not be duplicated or duplication minimized. Think modular and reusable code.
E. Remember -
Do not define methods that take any decimal values as input in either the base or derived classes.
Only the print method(s) in the classes should print anything to console.
Throw String (or equivalent) exceptions from within the classes to ensure that invalid objects cannot be created.
F. In your main:
Declare a primitive array of 5 Currency references (for C++ programmers, array of 5 Currency pointers).
Ask the user for 5 decimal numbers to be input - for each of the inputs you will create one Money object to be stored in the array.
Once the array is filled, perform the following five operations:
Print the contents of the array of objects created in long form, i.e. if the user entered "2.85" for the first value, it should be printed as "2 Dollar 85 Cent".
Add the first Money object to the second and print the resulting value in long form as above.
Subtract the first Money object from the third and print the resulting value in long form as above.
Compare the first Money object to the fourth and print whether both objects are equal or not using long form for object values.
Compare the first Money object to the fifth and print which object value is greater than the other object value in long form.
All operations in the main should be performed on Currency objects demonstrating polymorphism.
Remember to handle exceptions appropriately.
There is no sample output - you are allowed to provide user interactivity as you see fit.

What are the advantages of using a database management system (DBMS) over using file-based data storage?
Answer:
Advantage of DBMS over file system
No redundant data: Redundancy removed by data normalization. No data duplication saves storage and improves access time.
Data Consistency and Integrity: As we discussed earlier the root cause of data inconsistency is data redundancy, since data normalization takes care of the data redundancy, data inconsistency also been taken care of as part of it
Data Security: It is easier to apply access constraints in database systems so that only authorized user is able to access the data. Each user has a different set of access thus data is secured from the issues such as identity theft, data leaks and misuse of data.
Privacy: Limited access means privacy of data.
Easy access to data – Database systems manages data in such a way so that the data is easily accessible with fast response times.
Easy recovery: Since database systems keeps the backup of data, it is easier to do a full recovery of data in case of a failure.
Flexible: Database systems are more flexible than file processing systems
