Write a C program to define a class called Student with data members as roll, name and marks. Define the appropriate member functions, 1)setdata 2)display for reading and displaying the data and also define a member function called sort to sort 5 students records according to roll, name
Answers
The C program defines a class called Student with data members roll, name, and marks. It includes member functions setdata and display for reading and displaying the data. It also defines the sort member function to sort 5 student records based on roll and name.
Below is an example of a C program that defines a class called Student with the required data members and member functions:
#include<stdio.h>
#include<string.h>
struct Student {
int roll;
char name[50];
float marks;
};
void setdata(struct Student *s) {
printf("Enter roll number: ");
scanf("%d", &(s->roll));
printf("Enter name: ");
scanf("%s", s->name);
printf("Enter marks: ");
scanf("%f", &(s->marks));
}
void display(struct Student s) {
printf("Roll number: %d\n", s.roll);
printf("Name: %s\n", s.name);
printf("Marks: %.2f\n", s.marks);
}
void sort(struct Student arr[], int size) {
struct Student temp;
int i, j;
for (i = 0; i < size-1; i++) {
for (j = 0; j < size-i-1; j++) {
if (arr[j].roll > arr[j+1].roll) {
temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
else if (arr[j].roll == arr[j+1].roll && strcmp(arr[j].name, arr[j+1].name) > 0) {
temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
}
}
}
int main() {
struct Student students[5];
int i;
In this program, a structure named Student is defined with the required data members. The setdata function reads the student details from the user. The display function prints the student details. The sort function sorts the student records based on roll number and name using bubble sort algorithm. Finally, in the main function, the program reads the details of 5 students, sorts the records using the sort function, and displays the sorted records.

I ONLY NEED HELP WITH QUESTION 6 SHOWING HOW TO USE EXCEL FORMULA WHEN FINDING THE ANSWER:EXERCISE 8: USING "LOOKUP" AND "COUNTIF" FUNCTIONS TO RANK EMPLOYEE PERFORMANCE Managers often like to rank employees performance. One scheme called "20-70-10," or more disparagingly as "Rank and Yank," categorizes the top 20 percent of employees as "Best," the middle 70 percent of employees "Near Best," and the bottom 10 percent as "Below Best." Go to the "Excel Student Spreadsheets BUS 2000" and click on the tab/worksheet labeled "Lookup". There you will find the performance ratings—on a ten-point scale—for 20 employees. Each employee has 3 performance ratings. • In the 5th Column, or Column E, calculate the average performance rating for each employee to one decimal place. • Then, in the 6th Column, or Column F, use the LOOKUP function below to classify the employees. o =LOOKUP(E2,{0,4,9,10},{"Below Best", "Near Best", "Best"}) The Lookup formula is structured as follows: • E2 is the Cell containing the data for which the calculation should be made. • 0 to 4 is the classification of "Below Best". • 4 to 9 is the classification of "Near Best". • 9 to 10 is the classification of "Best". • The words "Below Best", "Near Best", and "Best" are placed for each of the three classifications according to an employee’s average rating. Using the results, do the following: 1. List the names of the "Best" employees 2. List the names of the "Near Best" employees 3. List the names of the "Below Best" employees Next, redefine the Lookup function to classify employees as "Above Average" and "Below Average" based on whether they scored above or below an average of 5 in their three performance scores. Place the results in the 7th Column, or Column G. Next, we’re going to count how many employees were categorized as either "Above Average" or "Below Average". Place the following results in cells B23 and B24. 4. How many people scored "Above Average?" 5. How many people scored "Below Average?"To answer these questions, use the COUNTIF function. Its form is =COUNTIF(G2:G21, "Above Average"), where G2:G21 is the range of cells. In this example, the function counts the number of employees that were "Above Average" according to the former classification.Lastly, you will notice that more people scored "Above Average" than "Below Average" using 5 as the cut point. Redefine the LOOKUP formula so that a roughly equal number of employees are classified as "Above Average" and as "Below Average." 6. What is the new cutoff point?
Answers
The new cutoff point to classify employees as "Above Average" or "Below Average" is 4. This ensures a roughly equal distribution of employees in both categories, taking into account an average score of 5 as the dividing point.
To determine the new cutoff point in order to classify an equal number of employees as "Above Average" and "Below Average," we need to adjust the ranges in the LOOKUP function. Let's walk through the steps to find the new cutoff point
Step 1: Calculate the average performance rating for each employee in Column E.
Step 2: Use the LOOKUP function in Column F to classify employees as "Below Best," "Near Best," or "Best" based on their average rating. The formula is as follows:
=LOOKUP(E2, {0, 4, 9, 10}, {"Below Best", "Near Best", "Best"}
Step 3: List the names of the employees classified as "Best" in one column, the names of the employees classified as "Near Best" in another column, and the names of the employees classified as "Below Best" in a third column.
Step 4: Redefine the LOOKUP function in Column G to classify employees as "Above Average" or "Below Average" based on whether they scored above or below an average of 5 in their three performance scores. The formula is as follows:
=LOOKUP(E2, {0, 5, 10}, {"Below Average", "Above Average"}
Step 5: Use the COUNTIF function to count the number of employees categorized as "Above Average" and "Below Average." Place the results in cells B23 and B24. The formulas are as follows
B23: =COUNTIF(G2:G21, "Above Average")
B24: =COUNTIF(G2:G21, "Below Average")
Step 6: Compare he counts of employees classified as "Above Average" and "Below Average." If there are more employees classified as "Above Average," we need to adjust the cutoff point to achieve a roughly equal distribution.
To find the new cutoff point, we can adjust the ranges in the LOOKUP function in Column G. We want to divide the range of scores evenly between "Below Average" and "Above Average." Let's say we have N employees in total, and we want to divide them equally.
The new rnges in the LOOKUP function can be calculated as follows:
"Below Average" range: 0 to (5 - 1)
"Above Average" range: (5 - 1) to 1
Here, (5 - 1) represents the new cutoff point. We subtract 1 because we want to exclude the exact average score of 5 from either classification.
Therefore, the new cutoff point is 4.

The PAV has been under development for 21 years at a total cost of $85 million. Assuming the $85 million was spent in an equal amount each year, determine the future worth at the end of the 21 -year period at an interest rate of 10% per year. The future worth is $
Answers
The future worth of the Moller Skycar M400 project after 21 years can be calculated using the concept of future value. To determine the future worth, we need to calculate the compound interest on the $85 million spent each year at an interest rate of 10% per year.
To calculate the future worth, we can use the formula for compound interest:
Future Worth = Present Worth * (1 + Interest Rate)^Number of Years
Since the $85 million was spent in equal amounts each year, the present worth can be calculated as the annual expenditure, which is $85 million.
Plugging the values into the formula:
Future Worth = $85 million * (1 + 0.10)^21
Simplifying the calculation:
Future Worth = $85 million * (1.10)^21
Calculating the exponent:
Future Worth = $85 million * 6.728
Therefore, the future worth of the Moller Skycar M400 project after 21 years, at an interest rate of 10% per year, is $572.38 million.
Please note that the calculation assumes equal amounts were spent each year and does not account for any potential income generated by the project. Additionally, the actual future worth may vary based on various factors.

which is a function of the logical link control (llc) sublayer?
Answers
The logical link control (LLC) sublayer is responsible for providing a logical link between network layers and controlling the flow of data between them.
Its main function is to ensure that data is delivered error-free, in the correct order, and with the appropriate level of control. Specifically, the LLC sublayer is responsible for framing and sequencing data, providing error checking, and implementing flow control mechanisms to regulate the flow of data between the sender and receiver.The Logical Link Control (LLC) is a sublayer of the data link layer in the OSI networking model. It is responsible for providing a reliable link between two network nodes, ensuring that data is transmitted and received correctly. The LLC sublayer provides services to the upper layers of the OSI model, enabling them to exchange data between devices. It handles the flow control and error detection of data transmission, and can initiate error recovery procedures if necessary. One of the main functions of the LLC is to provide a consistent interface to the upper layers of the OSI model, regardless of the specific physical link technology used. This enables different types of network devices to communicate with each other, even if they are connected by different types of physical links (such as Ethernet or Token Ring). The LLC sublayer is implemented in hardware in many network devices, including network interface cards and routers. It is an essential component of many networking protocols, including Ethernet, Token Ring, and FDDI (Fiber Distributed Data Interface).

Confidentiality
Privacy
Availability
Describe one of the resources available through the U.S. Computer Emergency Readiness Team (US-CERT) and indicate how it could assist a business with their e-commerce activities.
Part of US-CERT’s role is to share information about existing or potential threats through the Cybersecurity and Infrastructure Security Agency (CISA). View the CISA National Cyber Awareness System, select one security incident posted within the last 30 days, provide a brief description, and indicate how it could assist a business with safeguarding their e-commerce system.
Answers
If the integrity of an e-commerce system is compromised or attacked, it could result in unauthorized modification or alteration of data. For example, an attacker could manipulate product prices or change order details, leading to financial losses and a loss of customer trust.
Nonrepudiation refers to the assurance that a party cannot deny the authenticity of their actions or transactions. If nonrepudiation is compromised, it becomes difficult to hold individuals accountable for their actions, such as denying making a purchase or disputing a transaction.
If authenticity is compromised, it means that the identity of a user or entity cannot be verified. This can lead to unauthorized access to systems, fraudulent activities, and breaches of trust within e-commerce transactions.
Confidentiality refers to protecting sensitive information from unauthorized access. If confidentiality is compromised, sensitive data such as customer information, payment details, or trade secrets may be exposed, leading to identity theft, financial loss, or reputational damage.
Privacy in e-commerce ensures that personal information is collected, used, and stored in accordance with relevant privacy laws and regulations. If privacy is compromised, customer data may be mishandled or exposed, leading to privacy breaches, legal consequences, and damage to the company's reputation.
Availability refers to the accessibility and uninterrupted functioning of e-commerce systems. If availability is compromised, the system may experience downtime, slow response times, or become inaccessible to users, resulting in loss of sales, customer dissatisfaction, and damage to the company's reputation.
An example resource available through the U.S. Computer Emergency Readiness Team (US-CERT) is their Security Tips publication. This resource provides practical guidance and best practices for businesses to enhance their cybersecurity posture and safeguard their e-commerce activities. It covers various topics such as secure coding, secure network configuration, password management, and secure e-commerce practices.

The maximum width of the NUMBER datatype in Oracle is 38 digits. This means that a NUMBER column can hold up to 38 digits of precision and scale. The precision refers to the total number of digits that can be stored, while the scale refers to the number of digits to the right of the decimal point.
It is important to note that the maximum precision of a NUMBER column can be reduced by specifying a scale. For example, if a column is defined as NUMBER(10,2), it can only store up to 10 digits of precision, with 2 digits to the right of the decimal point.
In addition to the NUMBER datatype, Oracle also provides several other numeric datatypes, such as INTEGER, FLOAT, and DECIMAL. These datatypes have different ranges and levels of precision, so it is important to choose the right one for your specific needs.Overall, understanding the maximum width of the NUMBER datatype is important when designing a database schema and determining the appropriate data types for your columns.The maximum width of the NUMBER datatype is 38 digits. The NUMBER datatype is used in various programming languages and databases to store numeric values with a high level of precision. With a maximum width of 38 digits, it allows for a broad range of numeric values, making it a versatile choice for handling mathematical operations and data storage.
