Write a complete Java program that do the following: 1. Get student information (first name and last name) from the user and store it in the array named studentName (first name and last name are stored in the first and last index of the studentName array). 2. Print elements of the array studentName using enhanced for statement. 3. Get student's ID from the user, store it in the array named studentID and print it 4. Find and print the sum and average of the array- studentID.
Answers
The Java program collects student information, stores it in arrays, and then prints the names and ID of the students. It also calculates and prints the sum and average of the student IDs.
```
import java.util.Scanner;
public class StudentInformation {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String[] studentName = new String[2];
System.out.print("Enter student's first name: ");
studentName[0] = scanner.nextLine();
System.out.print("Enter student's last name: ");
studentName[1] = scanner.nextLine();
System.out.println("Student Name:");
for (String name : studentName) {
System.out.println(name);
}
int[] studentID = new int[5]; // Assuming 5 students
for (int i = 0; i < studentID.length; i++) {
System.out.print("Enter student's ID: ");
studentID[i] = scanner.nextInt();
}
System.out.println("Student IDs:");
for (int id : studentID) {
System.out.println(id);
}
int sum = 0;
for (int id : studentID) {
sum += id;
}
double average = (double) sum / studentID.length;
System.out.println("Sum of Student IDs: " + sum);
System.out.println("Average of Student IDs: " + average);
scanner.close();
}
}
```
In this Java program, we start by creating a Scanner object to read user input. We then declare and initialize two arrays: `studentName` (of size 2) to store the first and last names of the student, and `studentID` (of size 5 in this example) to store the student IDs.
We prompt the user to enter the first name and last name, and store them in the corresponding indices of the `studentName` array. We then use an enhanced for loop to print each element of the `studentName` array.
Next, we use a regular for loop to prompt the user to enter the student IDs and store them in the `studentID` array. Again, we use an enhanced for loop to print each element of the `studentID` array.
Finally, we calculate the sum of all the student IDs by iterating over the `studentID` array, and then calculate the average by dividing the sum by the length of the array. We print the sum and average to the console.

Answers
False. We cannot represent the pdf of a discrete random variable X with a histogram.
The probability density function or pdf refers to the mathematical function that is used to describe the likelihood of possible values of a continuous random variable. A probability density function is represented as the derivative of a probability distribution function, and it is used to represent the area under the curve that represents the probability distribution of a continuous random variable. The probability density function (pdf) is used to estimate the probability of the random variable X by observing the probability distribution function (pdf) of X. The probability distribution function (pdf) of X is defined as P(X = x) = the probability of X taking on the value x. The probability density function is used to estimate the probability of the random variable X by observing the probability distribution function (pdf) of X.

Pointer: Pointer arithmetic first requires that you do what before adding the value to the pointer value aka address?
Answers
Dereference the pointer to obtain the value at the memory address before adding the value to the pointer value.
Pointer arithmetic involves performing arithmetic operations on a pointer, which results in the modification of the pointer's value or address.
However, before adding a value to the pointer value or address, it is necessary to determine the size of the data type to which the pointer is pointing.
This is because pointer arithmetic is based on the size of the data type to which the pointer is pointing, and the size of the data type can vary depending on the system architecture.
Therefore, it is essential to determine the correct size of the data type before performing pointer arithmetic to ensure that the calculations are accurate and that the pointer is pointing to the correct memory location.

Answers
The essential feature of a while loop having the form while (loopexpression) { loopbody } is that the loopexpression should not be affected by the loopbody.
The loopexpression is evaluated at the beginning of each iteration of the loop and determines whether the loopbody will be executed or not. If the loopexpression is true, then the loopbody will be executed, and if it is false, then the loop will terminate. It is important that the loopexpression is not changed within the loopbody, as this could lead to unexpected behavior and potentially infinite loops. Therefore, option B is the correct answer for this question. This is a long answer but it covers all the necessary information.
This is because the loop continues to execute as long as the loopexpression is true, and the loopbody should contain code that eventually modifies the condition, allowing the loop to terminate.
