Write a superclass encapsulating a rectangle. A rectangle has two attributes representing the width and the height of the rectangle. It has methods returning the perimeter and the area of the rectangle. This class has a subclass, encapsulating a parallelepiped, or box. A parallelepiped has a rectangle as its base, and another attribute, its length; it has two methods that calculate and return its area and volume. You also need to include a client class to test these two classes.

Answer:
o.o
Explanation:
First, open two separate terminal connections to the same machine, so that you can easily run something in one window and the other. Now, in one window, run vmstat 1, which shows statistics about machine usage every second. Read the man page, the associated README, and any other information you need so that you can understand its output. Leave this window running vmstat for the rest of the exercises below. Now, we will run the program mem.c but with very little memory usage. This can be accomplished by typing ./mem 1 (which uses only 1 MB of memory). How do the CPU usage statistics change when running mem
Do the same exercise but this time use the value returning function. Here is the skeleton of the main function. Write functions definition according to the function call. Note: Do not change the main(). Copy it as it is. Must define the function after the main(). Make sure you write the function prototype before main(). // function prototype.
Answer:
The function prototypes are as follows:
int findSum(int fn, int sn, int tn);
int findMin(int fn, int sn, int tn);
int findMax(int fn, int sn, int tn);
The functions are as follows:
int findSum(int fn, int sn, int tn){
return fn+sn+tn;}
int findMin(int fn, int sn, int tn){
int min = fn;
if(sn<=min && sn<=tn){
min = sn; }
if(tn <= min && tn <= sn){
min = tn; }
return min;}
int findMax(int fn, int sn, int tn){
int max = fn;
if(sn>=max && sn>=tn){
max = sn; }
if(tn>=max && tn>=sn){
max = tn; }
return max;}
Explanation:
Given
See attachment 1 for the main function
Required
Write the following functions
findSumfind MinfindMax.The following represents the function prototypes
int findSum(int fn, int sn, int tn);
int findMin(int fn, int sn, int tn);
int findMax(int fn, int sn, int tn);
This declares the findSum function
int findSum(int fn, int sn, int tn){
This returns the sum of the three numbers
return fn+sn+tn;}
This declares the findMin function
int findMin(int fn, int sn, int tn){
This initialzes min (i.e. minumum) to fn
int min = fn;
This checks if sn is the minimum
if(sn<=min && sn<=tn){
min = sn; }
This checks if tn is the minimum
if(tn <= min && tn <= sn){
min = tn; }
This returns the minimum of the three numbers
return min;}
This declares the findMax function
int findMax(int fn, int sn, int tn){
This initialzes max (i.e. maximum) to fn
int max = fn;
This checks if sn is the maximum
if(sn>=max && sn>=tn){
max = sn; }
This checks if tn is the maximum
if(tn>=max && tn>=sn){
max = tn; }
This returns the maximum of the three numbers
return max;}

Write a short note on the topic ,' My Brother'.
Answer:
I have an older brother whose name is Michael.
He is two years older than me and studies in Class 3.
My brother has a round face with black hair and brown eyes.
He is very caring, loving and outgoing by nature.
He takes care of me, whenever my parents are not at home.
He shares his toys with me, whenever we are playing indoors.
My brother is a well-mannered boy who is loved by everyone.
He is very good in his studies and helps me in my studies too.
He is very sincere and intelligent and never misses his school.
I love my brother and always pray to God to help us maintain a strong bond forever.
Explanation:
Answer:
Explanation:
To begin with, a brother is an important member of the family because he loves his siblings like a father, cares like a mother and sometimes annoys his sister(s). Sibling relationships usually tend to be emotionally powerful. Therefore, building a strong brother-sister relationship is important not only in childhood, but for the entire lifetime. Siblings learn social skills from each other like negotiating power and managing conflicts among themselves.
You have been given an encrypted copy of the Final exam study guide here, but how do you decrypt and read it???
Along with the encrypted copy, some mysterious person has also given you the following documents:
helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.
hints.txt -- Seems important.
In a file called pa11.py write a method called decode(inputfile,outputfile). Decode should take two parameters - both of which are strings. The first should be the name of an encoded file (either helloworld.txt or superdupertopsecretstudyguide.txt or yet another file that I might use to test your code). The second should be the name of a file that you will use as an output file. For example:
decode("superDuperTopSecretStudyGuide.txt" , "translatedguide.txt")
Your method should read in the contents of the inputfile and, using the scheme described in the hints.txt file above, decode the hidden message, writing to the outputfile as it goes (or all at once when it is done depending on what you decide to use).
Hint: The penny math lecture is here.
Another hint: Don't forget about while loops...
Mac hint: use encoding="utf-8" in your file open functions, like this:
Mac hint: use encoding="ascii" in your file open functions, like this:
fin = open(input_file,"r",encoding="ascii")
Answer:
You use a decoder
Explanation:

Given two integers as user inputs that represent the number of drinks to buy and the number of bottles to restock, create a VendingMachine object that performs the following operations:
Purchases input number of drinks Restocks input number of bottles.
Reports inventory Review the definition of "VendingMachine.cpp" by clicking on the orange arrow.
A VendingMachine's initial inventory is 20 drinks.
Ex: If the input is: 5 2
the output is: Inventory: 17 bottles
Answer:
In C++:
#include <iostream>
using namespace std;
class VendingMachine {
public:
int initial = 20;};
int main() {
VendingMachine myMachine;
int purchase, restock;
cout<<"Purchase: "; cin>>purchase;
cout<<"Restock: "; cin>>restock;
myMachine.initial-=(purchase-restock);
cout << "Inventory: "<<myMachine.initial<<" bottles";
return 0;}
Explanation:
This question is incomplete, as the original source file is not given; so, I write another from scratch.
This creates the VendingMachine class
class VendingMachine {
This represents the access specifier
public:
This initializes the inventory to 20
int initial = 20;};
The main begins here
int main() {
This creates the object of the VendingMachine class
VendingMachine myMachine;
This declares the purchase and the restock
int purchase, restock;
This gets input for purchase
cout<<"Purchase: "; cin>>purchase;
This gets input for restock
cout<<"Restock: "; cin>>restock;
This calculates the new inventory
myMachine.initial-=(purchase-restock);
This prints the new inventory
cout << "Inventory: "<<myMachine.initial<<" bottles";
return 0;}
Write a program that asks the user to enter their yearly income. The program should display the user's tax bracket according to the following guidelines: Income below $50,000: Tax Bracket 1 Income of $50,000 - $99,999.99: Tax Bracket 2 Income of $100,000 or above: Tax Bracket 3 The program should then output the amount of federal taxes they will have to pay given that the Federal Tax Rate is 15% (for all tax brackets).
Answer:
Explanation:
The following Python code asks the user for their yearly income as an input, saves it into a variable called income. Then it analyzes that value and outputs their correct Tax Bracket using IF statements. Then it calculates the amount of tax they must pay and outputs that value.
income = input("Enter your yearly income: ")
if int(income) < 50000:
print("You are in Tax Bracket 1")
elif (int(income) >= 50000) and (int(income) <= 99999.99):
print("You are in Tax Bracket 2")
else:
print("You are in Tax Bracket 3")
tax = int(income) * 0.15
print("You need to pay a total of $" + str(tax) + " in income tax")

is pseudocode obtained from Algorithm or is Algorithm obtained from pseudocode?
Answer:
An algorithm is defined as a well-defined sequence of steps that provides a solution for a given problem, whereas a pseudocode is one of the methods that can be used to represent an algorithm.
hope this gives you at least an idea of the answer:)
1) Create a method Sum to include a FOR loop. Get a scanner and input a number form the keyboard in main(). The method will take one parameter and calculate the sum up to that number. For example, if you pass 5, it it will calculate 1+2+3+4+5 and will return it back to main() method. Main method should call the method, get the sum back, and print a sum. You call the method from main() and get the result back to main() 2) Create another method: Factorial that calculates a Product of same numbers, that Sum does for summing them up. Make sure you use FOR loop in it. 3) Make a switch that Calls either sum(...) method OR factorial(...) method, depending on what user of the program wants. Ask the user to enter a selection, after the number is entered, such as "do sum" or "do factorial", read it with the Scanner next(), then call the appropriate method in a switch.
Answer:
Explanation:
The following Java code creates both methods using a for loop. Asks the user for the value and choice of method within the main() and uses a switch statement to call the correct method.
import java.util.Scanner;
class Brainly {
static Scanner in = new Scanner(System.in);
public static void main(String[] args) {
System.out.println("Enter a value: ");
int userValue = in.nextInt();
System.out.println("Enter a Choice: \ns = do Sum\nf = do Factorial");
String choice = in.next();
switch (choice.charAt(0)) {
case 's': System.out.println("Sum of up to this number is: " + sum(userValue));
break;
case 'f': System.out.println("Factorial of up to this number is: " + factorial(userValue));
break;
default: System.out.println("Unavailable Choice");
}
}
public static int sum(int userValue) {
int sum = 0;
for (int x = 1; x <= userValue; x++) {
sum += x;
}
return sum;
}
public static int factorial(int userValue) {
int factorial = 1;
for (int x = 1; x <= userValue; x++) {
factorial *= x;
}
return factorial;
}
}
