Explanation:
The Westfield Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms. To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carpet. For example, the area of floor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpet that costs $8 per square foot would cost $960. (12 × 10 × 8 = 960.) First, you should create a class named RoomDimension that has two FeetInches objects as attributes: one for the length of the room and one for the width. (You should use the version of the FeetInches class that you created in Programming Challenge 11 with the addition of a multiply member function. You can use this function to calculate the area of the room.) The RoomDimension class should have a member function that returns the area of the room as a FeetInches object. Next, you should create a RoomCarpet class that has a RoomDimension object as an attribute. It should also have an attribute for the cost of the carpet per square foot. The RoomCarpet class should have a member function that returns the total cost of the carpet. Once you have written these classes, use them in an application that asks the user to enter the dimensions of a room and the price per square foot of the desired carpeting. The application should display the total cost of the carpet.

10. Differentiate between equity share & preference share.
Answer:
Equity Shares are commonly called Common shares and have both advantages and disadvantages over Preference shares.
Equity shareholders are allowed to vote on company issues while preference shareholders can not.Preference shareholders get paid first between the two in the case that the company liquidates from bankruptcy. Preference shareholders get a fixed dividend that has to be paid before equity share dividends are paid. Preference shareholders can convert their shares to Equity shares but equity shareholders do not have the same courtesy.Preference shares can only be sold back to the company while equity shares can be sold to anybody.

Extend the functionality of cout by implementing a friend function in Number.cpp that overloads the insertion operator. The overloaded insertion operator returns an output stream containing a string representation of a Number object. The string should be in the format "The value is yourNum", where yourNum is the value of the integer instance field of the Number class.Hint: the declaration of the friend function is provided in Number.h.Ex: if the value of yourNum is 723, then the output is:
Answer:
// In the number.cpp file;
#include "Number.h"
#include <iostream>
using namespace std;
Number::Number(int number)
{
num = number;
}
void Number::SetNum(int number)
{
num = number;
}
int Number::GetNum()
{
return num;
}
ostream &operator<<(ostream &out, const Number &n)
{
out << "The value is " << n.num << endl;
return out;
}
// in the main.cpp file;
#include "Number.cpp"
#include <iostream>
using namespace std;
int main()
{
int input;
cin >> input;
Number num = Number(input);
cout << num;
return 0;
}
Explanation:
The main function in the main.cpp file prompts the user for the integer value to be displayed. The Number file contains defined functions and methods of the number class to set, get and display the "num" variable.

In this lab, you use the flowchart and pseudocode found in the figures below to add code to a partially created C++ program. When completed, college admissions officers should be able to use the C++ program to determine whether to accept or reject a student, based on his or her test score and class rank.
start input testScore,
classRank if testScore >= 90 then if classRank >= 25 then output "Accept"
else output "Reject" endif else if testScore >= 80
then if classRank >= 50 then output "Accept" else output "Reject" endif
else if testScore >= 70
then if classRank >= 75 then output "Accept"
else output "Reject"
endif else output "Reject"
endif
endif
endif
stop
Study the pseudocode in picture above. Write the interactive input statements to retrieve: A student’s test score (testScore) A student's class rank (classRank) The rest of the program is written for you. Execute the program by clicking "Run Code." Enter 87 for the test score and 60 for the class rank. Execute the program by entering 60 for the test score and 87 for the class rank.
[comment]: <> (3. Write the statements to convert the string representation of a student’s test score and class rank to the integer data type (testScore and classRank, respectively).)
Function: This program determines if a student will be admitted or rejected. Input: Interactive Output: Accept or Reject
*/ #include using namespace std; int main()
{ // Declare variables
// Prompt for and get user input
// Test using admission requirements and print Accept or Reject
if(testScore >= 90)
{ if(classRank >= 25)
{ cout << "Accept" << endl; }
else
cout << "Reject" << endl; }
else { if(testScore >= 80)
{ if(classRank >= 50)
cout << "Accept" << endl;
else cout << "Reject" << endl; }
else { if(testScore >= 70)
{ if(classRank >=75) cout << "Accept" << endl;
else cout << "Reject" << endl; }
else cout << "Reject" << endl; } } } //End of main() function
Answer:
The equivalent program in C++:
#include<iostream>
#include <sstream>
using namespace std;
int main(){
string Score, Rank;
cout<<"Enter student score and class rank: ";
cin>>Score>>Rank;
int testScore = 0, classRank = 0;
stringstream sstream(Score);
sstream>>testScore;
stringstream tream(Rank);
tream>>classRank;
if (testScore >= 90){
if(classRank >=25){cout<<"Accept";}
else{cout<<"Reject";}
}
else if(testScore >= 80){
if(classRank >=50){cout<<"Accept";}
else{cout<<"Reject";}
}
else if(testScore >= 70){
if(classRank >=75){cout<<"Accept";}
else{cout<<"Reject";}
}
else{cout<<"Reject";}
return 0;
}
Explanation:
This declares Score and Rank as string variables
string Score, Rank;
This prompts the user for score and class rank
cout<<"Enter student score and class rank: ";
This gets the user input
cin>>Score>>Rank;
This declarees testScore and classRank as integer; and also initializes them to 0
int testScore = 0, classRank = 0;
The following converts string Score to integer testScore
stringstream sstream(Score);
sstream>>testScore;
The following converts string Rank to integer classRank
stringstream tream(Rank);
tream>>classRank;
The following conditions implement the conditions as given in the question.
If testScore >= 90
if (testScore >= 90){
If classRank >=25
if(classRank >=25){cout<<"Accept";}
If otherwise
else{cout<<"Reject";}
} ---
If testScore >= 80
else if(testScore >= 80){
If classRank >=50
if(classRank >=50){cout<<"Accept";}
If otherwise
else{cout<<"Reject";}
}
If testScore >= 70
else if(testScore >= 70){
If classRank >=75
if(classRank >=75){cout<<"Accept";}
If otherwise
else{cout<<"Reject";}
}
For testScore less than 70
else{cout<<"Reject";}
Write two alternate functions specified below, each of which simply triples the variable count defined in main. These two functions are: a. Function tripleByValue that passes a copy of count by value, triples the copy and returns the new value.b. Function tripleByReference that passes count by reference via a reference parameter and triples the original value of count through its alias(i.e. the reference parameter)For example, if count
Answer:
Following are the code to this question:
#include <iostream>//header file
using namespace std;
int triplebyValue(int count)//defining a method triplebyValue
{
int x=count*3;//defining a variable x that multiply by 3 in the count
return x;//return value of x
}
void triplebyReference(int& count)//defining a method triplebyReference that hold count variable as a reference in parameter
{
count*=3;//multipling a value 3 in the count variable
}
int main()//main method
{
int count;//defining integer variable
count=triplebyValue(3);//use count to call triplebyValue method
cout<<"After call by value, count= "<<count<<endl;//print count value with message
triplebyReference(count);//calling a method triplebyReference
cout<<"After call by reference, count= "<<count<<endl;//print count value with message
return 0;
}
Output:
After call by value, count= 9
After call by reference, count= 27
Explanation:
In this code two methods "triplebyValue and triplebyReference" are declared, which accepts a count variable as a parameter, and in both multiply the count value by 3 and return its value.
Inside the main method, an integer variable "count" is declared that first calls the "triplebyValue" method and holds its value into count variable and in the next, the method value is a pass in another method that is "triplebyReference", and use print method to print both methods value with a message.
HTML, the markup language of the web, specifies colors using the RGB model. It uses a two-digit hexadecimal (that is, base 16) representation for each component of the vector, and concatenates the three numbers together to form one large, six-digit number. For instance, the HTML color code #80FF3B has red component 80, green component FF, and blue component 3B. In hexadecimal, the digits 0 through 9 have their usual meanings, but the letters A through F also function as digits, and have the meanings 10 through 15, respectively. Because hexadecimal means base 16, a two-digit number such as 3B thus has the meaning 16⋅3+11=59. The 16 is used because the 3 is in the 16s place, and the 11 is the meaning of the digit B. (If you found this introduction to hexadecimal notation too brief, consult the web for more details.) What is the maximum number representable with two hexadecimal digits?
Solution :
It is given that :
The digits 0 through 9 in hexadecimal have their usual meanings. But letters A through F function like the digits and it means digits 10 through 15, respectively.
Now the base of a hexadecimal is 16.
Now we know from 0 to 9 [tex]$\rightarrow$[/tex] A, B, C, D, E, F
Now the maximum two digits hexadecimal numbers are = F F
So, F F [tex]$= 16 \times 15 + 16^0 \times 15$[/tex]
= 255

if 100 KB file is stored in 2 MB folder how many files can be stored in the folder
Answer:
20 files.
Explanation:
Given the following data;
Size of file = 100 kilobytes.
Folder size (memory) = 2 megabytes.
Method 1
1000 kilobytes = 1 megabytes.
100 kilobytes = x megabytes
Cross-multiplying, we have;
1000x = 100
x = 100/1000
x = 0.1 mb
Now, to find the number of files that can be stored;
[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]
Substituting into the equation, we have;
[tex] Number \; of \; files = \frac {2}{0.1} [/tex]
Number of files = 20 files.
Method II
We know that;
1 kilobytes = 0.001 megabytes. 100 kilobytes = 0.1 megabytes. 1000 kilobytes = 1 megabytes. 2000 kilobytes = 2 megabytes.Substituting into the formula, we have;
[tex] Number \; of \; files = \frac {Memory}{Size \; of \; each \; file} [/tex]
Substituting into the equation, we have;
[tex] Number \; of \; files = \frac {2000}{100} [/tex]
Number of files = 20 files.

what is the impact of technology to the mankind
Modern technology has revolutionized the way people all over the world communicate and interact. This revolution has led to a system of globalization which has fundamentally changed modern society in both good and bad ways.
The most important technological change over the past 20 years is the advent and popularization of the Internet. The Internet connects billions of people around the globe and allows a type of connectivity in ways which the world has never seen. Companies are able to do business with consumers from other countries instantaneously, friends and families are able to talk to one another and see each other regardless of location, and information sits at the fingertips of every person with a computer, tablet or phone.
Outside of the digital world, modern advances in machinery and science have also impacted everyday life. The modernization of travel has allowed humans to span more miles in their lifetime than at any point in history, and the advancement of medicine has given people longer lifespans.
While these changes have certainly been for the better, there are also plenty of negative results of modernization and globalization. Because the Internet streamlines massive amounts of information, it can easily be exploited. The loss of privacy is one of the most pressing issues in the modern world.
Technology has also had an impact on the natural world. Industrialization has led to the destruction of natural life and has possibly caused negative effects on our climate.

Ram and Hari can finish a piece of work in 6 days and 12 days respectively in how many days will they finish it working together
Answer:
4 days
Explanation:
Given - Ram and Hari can finish a piece of work in 6 days and 12 days
respectively.
To find - In how many days will they finish it working together
Proof -
As given,
Ram and Hari can finish a piece of work in 6 days and 12 days respectively.
⇒1 day work of Ram done in = [tex]\frac{1}{6}[/tex]
1 day work of Hari done in = [tex]\frac{1}{12}[/tex]
If they work together,
1 day work of both together done in = [tex]\frac{1}{6}[/tex] + [tex]\frac{1}{12}[/tex] = [tex]\frac{2 + 1}{12} = \frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]
As we know Work is inversely proportional to efficiency
And efficiency = Person's 1 day work
As we have ,
1 day work of both together done in = [tex]\frac{1}{4}[/tex]
⇒ Total work done in 4 days if they work together.
