. Else-if is good selection statement that help us to solve problems in C++,mostly times same problem of same nature can also be solved via switch statement. Which one you prefer to use and why?
Answer:
Else-If statements
Explanation:
Personally, I prefer using Else-If statements for conditional statements since you can start with and If statement and add to it if necessary. Aside from this, Else-If statements also allow you to add more than one condition to be met by using tags such as and or and not. Switch statements are better in scenarios where you have a set of possible inputs or results and need a specific event to happen for each input/result, but this is not as common of a scenario so Else-If is usually my go-to conditional statement.

Which of the following can be used to replace ISSING CODE> so that the program works as intended for every possible list of positive numbers?
The missing code segment is meant to initialize the variable minimum to the first list element.
The missing code is (d) numList[0]
From the question, we understand that the first line of the program should determine the smallest number in the list numList
To do this, we start by initializing the variable minimum to the first element of numList
This is done using the following code segment:
var minimum = numList[0]
Hence, the missing code segment is (d) numList[0]

java Elements in a range Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain fewer than 20 integers. That list is followed by two more integers representing lower and upper bounds of a range. Your program should output all integers from the list that are within that range (inclusive of the bounds). For coding simplicity, follow each output integer by a comma, even the last one. The output ends with a newline. Ex: If the input is: 5 25 51 0 200 33 0 50 then the output is: 25,0,33, (the bounds are 0-50, so 51 and 200 are out of range and thus not output). To achieve the above, first read the list of integers into an array.
Answer:
The program in Java is:
import java.util.Scanner;
public class MyClass {
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
int n;
n = input.nextInt();
int [] mylist = new int[n+1];
mylist[0] = n;
System.out.print("List elements: ");
for(int i = 1;i<n+1;i++){
mylist[i] = input.nextInt();
}
int min,max;
System.out.print("Min & Max: ");
min = input.nextInt();
max = input.nextInt();
for(int i=1; i < mylist.length; i++){
if(mylist[i]>=min && mylist[i]<=max){
System.out.print(mylist[i]+" ");
}
}
}
}
Explanation:
This line declares length of list
int n;
This line gets length of list
n = input.nextInt();
This line declares the list/array
int [] mylist = new int[n+1];
This line initializes the element at index 0 to the length of the list
mylist[0] = n;
This prompts user for elements of the list/array
System.out.print("List elements: ");
The following iteration gets list elements
for(int i = 1;i<n+1;i++){
mylist[i] = input.nextInt();
}
This declares the lower and upper bound (min, max)
int min,max;
This line prompts user for elements of the list/array
System.out.print("Min & Max: ");
This next two lines get the bound of the list/array
min = input.nextInt();
max = input.nextInt();
The following iteration prints the elements in the range
for(int i=1; i < mylist.length; i++){
if(mylist[i]>=min && mylist[i]<=max){
System.out.print(mylist[i]+" ");
}
}

True or false: In relational databases, each individual space within a row or column contains exactly one value.
Answer:
True.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores. This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
A relational database can be defined as a type of database that is structured in a manner that there exists a relationship between its elements.
Hence, in relational databases, each individual space within a row or column contains exactly one value.

The name X is present in the list.
c. The name X should occur near the middle of the list.
Explanation:
Nancy's binary search for a name X should begin by comparing an element in the middle of the array or list with the name X (target value). If this name X's value matches the value of an element in the list, Nancy must return its position in the array. If the name X's value is less than the element's value, Nancy will continue the search in the lower half of the array. Usually, the name X should occur near the middle of the list or array.

Authorized agent Confidentiality Integrity Encryption 6:53 PM ______ means that only people with the right permission can access and use information.
Answer:
The answer is "Confidentiality"
Explanation:
Confidentiality alludes to shielding data from being gotten to by unapproved parties. All in all, solitary the individuals who are approved to do so can access delicate information. Imagine your bank records, You ought to have the option to get to them obviously, and representatives at the bank who are assisting you with an exchange ought to have the option to get to them, yet nobody else ought to. An inability to keep up Confidentiality implies that somebody who shouldn't have access has figured out how to get it, through deliberate act or coincidentally. Such a disappointment of Confidentiality, normally known as a breach can't be helped. When the secret has been uncovered, it is highly unlikely to un-uncover it.
Assuming your bank records are posted on a public site, everybody can realize your bank account number, balance, and so forth, and that data can't be eradicated from their brains, papers, PCs, and different spots. Virtually all the significant security occurrences reported in the media today include loss of Confidentiality.
Thus, in summary, a breach of Confidentiality implies that somebody accesses data who shouldn't be permitted to.
