In the above program, First, we accept the amount to be borrowed, interest rate per annum and the number of years to repay. We convert the number of years to months. We calculate the interest rate monthly by dividing the annual rate by 12. Next, we calculate the loan amount. After calculating the loan amount, we calculate the repayment amount monthly. We loop through the range of repay months and then calculate the interest to be paid, principal amount, and loan amount. Finally, we print out the payment schedule for the loans given out in terms of the payment month, interest paid, principal paid, and balance left after each payment.

The evaluation of the given expression yields the final answer of 3 x 10^17 N².

To evaluate the given expression, let's break it down step by step. We start with (50 mN) (6 GN) (50 mN) (6 GN).First, let's convert the units to the same base unit, which is Newton (N). 50 mN is equal to 50 x 10^(-3) N, and 6 GN is equal to 6 x 10^9 N.

Next, we multiply the values together:

(50 x 10^(-3) N) x (6 x 10^9 N) = 300 x 10^6 N²

To simplify the expression further, we convert the result to kilonewtons (KN). 1 kilonewton (KN) is equal to 1000 N.

Therefore, 300 x 10^6 N² is equal to 300 KN².

Finally, we multiply this result by (116) x (1000 N) to obtain the final answer. Multiplying 300 KN² by (116) x (1000 N) gives us 3 x 10^17 N².

The given code is not a complete code since it only provides a declaration of an integer variable named count and a comment that says constructor. This code would only be functional if it is part of a class or if it is placed within a function.

In programming, a constructor is a method that runs when a new object is created. The role of a constructor is to initialize the class variables and prepare the object for use. If a constructor is not defined, a default constructor is automatically provided by the compiler which initializes all the class variables to their default values. If a constructor is defined, then the default constructor will not be created, and it is the responsibility of the programmer to create a constructor to initialize the class variables.

A constructor is used to initialize the class variables and prepare the object for use. The constructor has the same name as the class and does not have any return type, not even void. When an object of the class is created, the constructor is called automatically.

OFDMA stands for Orthogonal frequency-division multiple access. It is a multiple-access technique used in both 4G and 5G communication systems. It is used to enable multiple users to share the same frequency channel simultaneously.

OFDMA achieves this by dividing the frequency band into several subcarriers. Each subcarrier can be used to transmit data to a different user, and this process is referred to as multi-user multiple-input multiple-output (MU-MIMO).

OFDMA divides the available bandwidth into multiple subcarriers that are orthogonal to each other, meaning they are mutually exclusive, and therefore don't interfere with each other. Each subcarrier uses OFDM (Orthogonal Frequency Division Multiplexing) modulation to carry data.

OFDM is a technique that uses a large number of closely spaced carriers that are orthogonal to each other to transmit data. The carriers are packed tightly together and the signal on each carrier is modulated with a low-rate data stream.

The OFDM symbol is the smallest unit of data that is transmitted using OFDM. It consists of multiple subcarriers, and each subcarrier carries a small piece of the overall data being transmitted.

The cyclic prefix is a guard interval added to each OFDM symbol to prevent inter-symbol interference. The cyclic prefix is a copy of the last few samples of the OFDM symbol appended to the beginning of the symbol. The length of the cyclic prefix is usually longer than the delay spread of the channel, which ensures that there is no overlapping of the OFDM symbols. Overall, OFDMA enables efficient use of available bandwidth and enables multiple users to share the same channel without interfering with each other.

Moving duplicated code reuse and inheritance from subclasses to their super class helps to promote code reusability and maintainability. By consolidating common code in the super class, we eliminate redundancy and reduce the risk of introducing bugs or inconsistencies when making changes.

When code is duplicated in subclasses, it can be more challenging to make updates or modifications. If a change needs to be applied to the duplicated code, it would require modifying each subclass separately. This approach can lead to code inconsistency and make maintenance more complex.

By moving the duplicated code to the super class, we can ensure that all subclasses inherit the common behavior. This centralizes the code logic in one place, making it easier to update or enhance in the future. Subclasses can focus on implementing their unique functionality while leveraging the shared code provided by the super class.

Additionally, moving duplicated code to the super class promotes the principles of object-oriented programming, such as inheritance and polymorphism. It allows for a more modular and extensible design, enabling new subclasses to be added without duplicating code.

Therefore, moving duplicated code reuse and inheritance to the super class improves code organization, reduces redundancy, and simplifies maintenance and future enhancements.

The value to remove has a left subtree, but no right subtree.4. The value to remove has both a left and right subtree in which case we promote the largest value in the left subtree. In this case, we will be removing the node with the value 23 in the given tree. This node has both a left and right subtree, so we will promote the largest value in the left subtree, which is 14, to take its place.

To do this, we need to remove the 14 node from its current position and replace the 23 node with it. The node with the value 14 has a right subtree but no left subtree, so we will remove it using the second case. Since it is a leaf node, this is straightforward.

The reason you're getting the error "lvalue required as left operand of assignment" is that you cannot assign a value to a returned value of a member function. It's a temporary value, and it can't be assigned a new value. The statement `pointer->Function() = pointer->Function() + 1;` won't work because `pointer->Function()` returns a temporary value.

Instead, you should use a temporary variable to store the returned value and then increment it. Here's the corrected code:

Object *pointer;
pointer = new Object(someUnimportantValue);
int temp = pointer->Function();
temp = temp + 1;
pointer->SetFunction(temp);

Here, I've created a temporary variable `temp` to store the value returned by `Function()`. Then, I've incremented `temp` by 1. Finally, I've used another member function called `SetFunction()` to set the new value of `m_value`. Here's what the implementation of `SetFunction()` should look like:void Object::SetFunction(int value)
{

}Note that `SetFunction()` is a member function of the `Object` class that takes an integer argument `value`. It sets the value of `m_value` to the value of the argument.

The image in the spatial domain will not be affected if we apply a filter H(u ,v) = A in the frequency domain to the image (x ,y).Explanation :Let's suppose that an image f(x ,y) is transformed using the DFT function and F(u ,v) is the result of the DFT of f(x ,y).

When we apply a filter function H(u, v) to the transformed image in the frequency domain, the appearance of the original image in the spatial domain is altered. In the inverse Fourier transform of F(u ,v), the filter function H(u, v) is multiplied with the transformed image and then the result is obtained in the spatial domain.

Thus, the image will be affected if a filter is applied to the image in the frequency domain .However, when a filter H(u ,v) = A (where A is a positive constant) is applied to the image in the frequency domain, it means that all the frequency components of the image are multiplied by a constant A.

As the constant is multiplied with the frequency components of the image, it will not alter the appearance of the original image in the spatial domain. Therefore, the image in the spatial domain will not be affected if we apply a filter H(u,v) = A in the frequency domain to the image

Any FIVE (5) advantages of backup and recovery of a database system are: Data Loss Prevention, Business Continuity, Data Integrity, Compliance and Legal Requirements and Disaster Recovery

Data Loss Prevention: One of the main advantages of backup and recovery in a database system is the prevention of data loss. By regularly backing up the database, you create copies of your data that can be restored in case of accidental deletion, hardware failure, or any other unforeseen circumstances. This ensures that your valuable data remains intact and accessible.

Business Continuity: Backup and recovery strategies contribute to business continuity. In the event of a system failure or a disaster, having a backup allows you to quickly restore the database and resume normal operations. This minimizes downtime and helps maintain business productivity, customer satisfaction, and revenue generation.

Data Integrity: Backing up a database helps maintain data integrity. Regular backups create checkpoints that capture a consistent snapshot of the database at a specific point in time. In case of data corruption or errors, you can restore the database to a known good state using a backup, ensuring the integrity and reliability of your data.

Compliance and Legal Requirements: Many industries have regulatory and legal requirements regarding data retention and protection. Backup and recovery processes help organizations meet these compliance requirements by ensuring data is backed up and available for retrieval when needed. It helps in maintaining audit trails, preserving evidence, and meeting legal obligations.

Disaster Recovery: Backup and recovery are crucial components of a disaster recovery plan. In the event of a natural disaster, cyberattack, or system failure, having a backup allows you to rebuild and restore your database to a functional state. It helps recover from catastrophic events, protects critical data, and minimizes the impact of such incidents on business operations.
