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.

If we were ever to use this pizza ordering program again, we would want to use mainline logic to control its execution. The way it is written, it will automatically execute as soon as it is imported.
Re-write this program, enclosing the top level code into the main function. Then execute the main function. Enter appropriate input so the output matches that under Desired Output.
# Define Function
def pizza(meat="cheese", veggies="onions"):
print("You would like a", meat, "pizza with", veggies)
# Get the User Input
my_meat = input("What meat would you like? ")
my_veggies = input("What veggie would you like? ")
# Call the Function
pizza(meat=my_meat, veggies=my_veggies)
desired output:
What meat would you like? cheese
What veggie would you like? onions
You would like a cheese pizza with onions
2) We want to generate 5 random numbers, but we need the random module to do so. Import the random module, so the code executes.
# Define main function
def main():
print("Your random numbers are:")
for i in range(5):
print(random.randint(1, 10))
# Call main function
main()
desired output:
Your random numbers are:
[x]
[x]
[x]
[x]
[x]
Answer:
Explanation:
The Python program has been adjusted. Now the pizza ordering function is called from the main() method and not as soon as the file is imported. Also, the random package has been imported so that the random.randint(1,10) can correctly create the 5 random numbers needed. The code has been tested and the output can be seen in the attached image below, correctly matching the desired output.
import random
def pizza(meat="cheese", veggies="onions"):
print("You would like a", meat, "pizza with", veggies)
def main():
# Get the User Input
my_meat = input("What meat would you like? ")
my_veggies = input("What veggie would you like? ")
# Call the Function
pizza(meat=my_meat, veggies=my_veggies)
print("Your random numbers are:")
for i in range(5):
print(random.randint(1, 10))

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.")

Ramjac Company wants to set up k independent file servers, each capable of running the company's intranet. Each server has average "uptime" of 98 percent. What must k be to achieve 99.999 percent probability that the intranet will be "up"?
Answer:
k = 3
Explanation:
K independent file servers
Average "uptime" of each server = 98%
To achieve 99.99% probability by the intranet
given that each server has an uptime = 98%
For the intranet to achieve 99.99% probability we have to choose more than 2 servers ( i.e. 3 servers ) incase any of the server goes down.
As each server posses an uptime of 98% it is almost impossible for all 3 servers to go down at the same time hence value of K = 3
It should be noted that the value of k to achieve 99.99 percent probability will be 3.
How to solve the probabilityFrom the information given, k is simply the independent file servers.
Also, the average uptime of each server is given as 98%. For the intranet to achieve 99.99% probability, it should be noted that more than 2 servers will be chosen.
In this case, it'll be impossible for the three servers to go down.

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

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.
