Write a C++ programme with classes which uses dynamic polymorphism to perform the right kind of transactional operations on the saved capital. The land investment class has data members like land rate and land area, while the mutual fund investment class has data members like unit share price and number of shares. Both these classes, in addition to their functions, essentially have a member function called transaction, which calculates the cost of individual transaction. Both these classes are derived from a class called investment which also has the same function name, transaction. Based on the choice given at runtime, your program should choose the appropriate transaction (from land investment and mutual fund investment). case=1 Input= 10 // land rate from 1st derived class 5 // land area 6 // unit share price from 2nd derived class // number of shares // option 1 land investment 4 1 output=50
Answers
The C++ program employs dynamic polymorphism to handle different types of investments. It defines three classes: land investment, mutual fund investment, and investment.
#include <iostream>
using namespace std;
class Investment {
public:
virtual void transaction() = 0; // Pure virtual function
};
class LandInvestment : public Investment {
private:
double landRate;
double landArea;
public:
LandInvestment(double rate, double area) : landRate(rate), landArea(area) {}
void transaction() {
double cost = landRate * landArea;
cout << "Land investment transaction cost: " << cost << endl;
}
};
class MutualFundInvestment : public Investment {
private:
double unitSharePrice;
int numShares;
public:
MutualFundInvestment(double price, int shares) : unitSharePrice(price), numShares(shares) {}
void transaction() {
double cost = unitSharePrice * numShares;
cout << "Mutual fund investment transaction cost: " << cost << endl;
}
};
int main() {
int choice;
double landRate, landArea;
double unitSharePrice;
int numShares;
cout << "Enter the land rate: ";
cin >> landRate;
cout << "Enter the land area: ";
cin >> landArea;

following fragment of code computes the matrix multiplication of a[n][n] and b[n][n]. give a bigo upper bound on the running time.
Answers
The upper bound on the running time is O(n³), where n is the size of the input matrices.
What is the upper bound on the running time?The provided code fragment computes the matrix multiplication of two matrices, a[n][n] and b[n][n]. To determine the upper bound on the running time, we need to analyze the nested loops involved in the matrix multiplication algorithm.
The code likely uses a triple nested loop structure, where each loop iterates n times. Since the matrix size is n × n, the number of iterations in each loop is proportional to n. As a result, the total number of iterations is n³.
Therefore, the running time of the code can be expressed as O(n³), indicating that the algorithm's time complexity grows cubically with the size of the input matrices.

Read the paragraph and use the RACE writing strategy to answer the questions.
Studies have found that the more time a teenager spends on social media, the more likely they are to suffer from anxiety and depression. Some people think that it is because they are developing fewer real-life connections to friends and spending less time playing outside. Another issue is cyber-bullying. Furthermore, teens feel bad when they see friends partaking in activities to which they have not been invited. Social media can make people feel isolated and like their life is less exciting than average, since people tend to publish their highlights on their feeds. Girls especially struggle with self-esteem issues, feel pressure to keep up with their peers who are dressing up, putting on makeup, and presenting their most polished selves to the world.
What are some of the risks involved with teens using social media? Explain. (Note that this is asking for reasons-plural-meaning you must give more than one reason.)
Answers
Answer:
i hope this help
Explanation:
Overuse of social media can have negative consequences on the well-being of adolescents. Social media use has been linked to lower self-esteem, increased depression, risk-taking behavior, and cyberbullying.
Social media can cause people to not be able to interact in real life. Sure you are talking to people, but not in a face to face conversation. It's easier to hide behind a screen than to talk to someone in the eye. So this can make them get anxious if they try to talk to people face to face. And peer pressure, teasing, can make teens stressed. Peer pressure can cause stress on teens thinking that they are not trying hard enough, or not living up to standards. Plus it can result in dangerous acts. Bullying can cause depression and make them think no one cares about them, and since this is behind a screen no one could know about the teen's problems. In short, Social media can cause stress, anxiety, depression, and dangerous acts from peer pressure.

what are the distinctions among logical,relative, and physical addresses?
Answers
The distinctions among logical, relative, physical addresses are as follows:
1. Logical address: A logical address, also known as a virtual address, is generated by the CPU during a program's execution. It is used as a reference to access data in memory. The logical address is mapped to a physical address through a memory management unit (MMU) before accessing the RAM.
2. Relative address: A relative address is an offset-based memory address, which is calculated relative to a known point, such as the current instruction pointer or a specific register. This makes it easier for programs to be relocatable, as the offset remains the same even when the base address changes.
3. Physical address: A physical address refers to the actual location of data in the RAM. It is a hardware-specific address used by the memory controller to access the data stored in memory cells. The MMU translates logical addresses into physical addresses during program execution.
In short, logical addresses are generated by the CPU and mapped to physical addresses through the MMU to access data in RAM, while relative addresses are offset-based and used for easier program relocation.

Answer: Its important.
Explanation:
Without government leaders visiting their areas of responsibility would be bad. Because of the people may have different opinions of stuff and there can be chaos and big debates and protests.
It is important that government leaders visit their areas of responsibility to talk to their constituents because this will impress the fact that they care for and empathize with their constituents. These gestures make a difference because they show an interest in the people who are being led.

Your cousin sold you his Pokemon cards for $24 10 years ago. You
sold them today for $502. What interest rate did you earn? (Convert
to a percent. Round to 2 decimal places.)
Answers
To calculate the interest rate earned on the sale of Pokemon cards, we need to determine the percentage increase in value over a 10-year period.
To find the interest rate earned, we can use the formula for simple interest: Interest = Principal * Rate * Time. In this case, the principal is the original purchase price ($24), the interest is the difference between the selling price ($502) and the principal, and the time is 10 years.
Using the formula, we can calculate the interest as follows:
Interest = Selling Price - Principal = $502 - $24 = $478.
Next, we divide the interest by the principal and multiply by 100 to convert it to a percentage:
Interest Rate = (Interest / Principal) * 100 = ($478 / $24) * 100 = 1991.67%.
Rounding to two decimal places, the interest rate earned on the sale of the Pokemon cards is approximately 1991.67%. This represents the percentage increase in value over the 10-year period.

A type of security control in which you unplug a computer from the internet to protect it from malware is:_______
Answers
A type of security control in which you unplug a computer from the internet to protect it from malware is Air-gapping.
Air-gapping is a type of security control used to isolate a computer or network from the internet or other external networks to protect it from malware attacks. With an air-gapped system, the computer or network is physically disconnected from the internet, preventing any network traffic from entering or leaving the system.
Air-gapping is often used in environments that require a high level of security, such as government agencies, financial institutions, and critical infrastructure, where sensitive data could be targeted by cyber-attacks.
Air gapping is considered a highly secure method of protecting a system, but it is not foolproof. Attackers can still breach the system through other means, such as physical access or the use of removable media, such as USB drives.
Air gapping can be expensive to implement, and it can limit the functionality and accessibility of the system. Therefore, it is usually reserved for high-security environments where the potential cost of a data breach is very high.
In conclusion, air-gapping is a type of security control in which a computer or network is physically disconnected from the internet or external networks to protect it from malware attacks. While highly secure, it is not foolproof and can limit functionality and accessibility, so it is typically reserved for high-security environments.
