Answers
Answer:
#include <iostream>
using namespace std;
int main() {
int num, check=0;
for(int num = 1; num<=100;num++){
for(int i = 2; i <= num/2; i++) {
if(num % i == 0) {
check=1;
break; } }
if (check==0) { cout <<num<<" "; }
check = 0;
}
return 0;
}
Explanation:
This line declares num as integer which represents digits 1 to 100.
A check variable is declared as integer and initialized to 0
int num, m=0, check=0;
This for loop iterates from 1 to 100
for(int num = 1; num<=100;num++){
This iterates from 2 to half of current digit
for(int i = 2; i <= num/2; i++) {
This checks for possible divisors
if(num % i == 0) {
If found, the check variable is updated to 1
check=1;
And the loop is terminated
break; } }
The following if statement prints the prime numbers
if (check==0) { cout <<num<<" "; }
check = 0;
}

What are the advantages and disadvantages of using steganography versus symmetric or asymmetric encryption
Answers
Explanation:
Steganography is a technique used in securing or hiding sensitive information by encrypting the information in a non-hidden file like a JPEG format. A major advantage of this method is that it reduces the risk of attack or break-in since the data is enclosed in a non-secure file; thereby reducing threats of any hack. One main disadvantage of this method is that the hidden message may become difficult to recover if the source file (non-secure file) used, is edited or deleted.
In symmetric or asymmetric encryption they both employ cryptographic encryption method. While symmetric encryption uses one key to encrypt and decrypt data, asymmetric encryption uses two keys (one for encryption, the other for decryption) of the data. A major advantage of using these methods is that they provide more security. Although while symmetric encryption is faster, asymmetric encryption is slower (eg using separate keys to gain access), a disadvantage.
Advantage:
Because the content is contained throughout a non-secure file, the above strategy decreases the chance of an assault on classified info.Disadvantage:
This approach has the disadvantage that concealed information might be able to retrieve if somehow the documents have been changed or deleted as of a non-secure file.Once again to encrypt as well as decode information, symmetric encryption employs a unique key, but asymmetric encryption utilizes two different keys, something for encryption as well as someone else for decryption.
Advantage:
One such approach is superior to steganography throughout the level of protection.Disadvantage:
Because distinct keys have been needed to get access, such techniques of asymmetric encryption are considerably slower.Thus the approach above is correct.

Explanation:
Write a program (using functions) starting from directives to compute and display the transpose of a matrix of dimension m x n. [Note: Here, transpose of a matrix means the element at row r and column c in the original is placed at row c and column r of the transpose]. (Programming in C)
Answers
Answer:
#include <iostream>
#include <cstdlib>
using namespace std;
int m, n;
void transpose(int matrix[]){
int transp[m][n];
for (int i = 0; i < n; i++){
for (int j = 0; j < m; j++){
transp[j][i] = matrix[i][j];
cout<< transp[j][i]<< " ";

}
transpose(mymatrix);
}
Explanation:
The C source code defined a void transpose function that accepts a matrix or a two-dimensional array and prints the transpose on the screen. The program gets user input for the row (n) and column (m) length of the arrays. The C standard library function rand() is used to assign random numbers to the array items.

How many permutations for a 7 characters in length string, which contains all following letters R, X, S, Y, T, Z, U, has either the string 'RXS' or string 'ZU' in the 7 characters string?
Answers
Answer:
Following are the solution to this question:
Explanation:
In the following forms, RXS can appear:
[tex]R X S \_ \_ \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
[tex]\_ R X S \_ \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
[tex]\_ \_ R X S \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
[tex]\_ \_ \_ R X S \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
[tex]\_ \_ \_ \_ R X S[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
And we'll have a total of [tex]24 \times 5 = 120[/tex] permutations with both the string RXS.
In the following forms, UZ can appear:
[tex]U Z \_ \_ \_ \_\ _[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ UZ \_ \_ \_ \_[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ \_ U Z \_ \_ \_[/tex]They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ \_ \_ U Z \_ \_[/tex]They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ \_ \_ \_ U Z \_[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ \_ \_ \_ \_ U Z[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
There may be [tex]120 \times 6 = 720[/tex] ways of complete permutations.

What is the main advantage of using a WYSIWYG (“what you see is what you get”) editor when constructing a website?
Only one programming language is required.
Websites may have more professional construction.
Knowledge of HTML is not required.
Website templates are not necessary.
Answers
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer among the given options to this question is:
Knowledge of HTML is not required.
Because when you are constructing a website using WYSIWYG (“what you see is what you get”) editor, then you don't need the knowledge of HTML. Because, when you use WYSIWYG editor to insert button, table, images, text, paragraph, etc. It will automatically insert HTML code behind the page. For example, you can insert a form and a submit button using drag and drop with the help of WYSIWYG (“what you see is what you get”) editor, for this purpose, you don't need exact knowledge of HTML. WYSIWYG (“what you see is what you get”) automatically inserts the HTML for the form and button on a website page.
While other options are not correct because:
Using the WYSIWYG (“what you see is what you get”) editor, you can use different programming languages in your website, such as VB.net, Asp.Net, C#, Javascript, Bootstrap, etc. It is not necessarily that you may have more professional construction and in WYSIWYG (“what you see is what you get”) website templates are mostly used and modified using WYSIWYG editor.

Answers
Answer:
Explanation:
The following function is written in Java and takes in three parameters the array, its size, and the chosenNumber that will be counted. The function then creates an instance variable called Counter and loops through the given array looking for the chosenNumber. Every time that the number is found in the array it adds 1 to the counter. Once the loop is done it returns the total value of the counter variable.
public static int counter(int[] numbers, int Size, int chosenNumber) {
int counter = 0;
for (int x = 0; x < Size; x++) {
if(numbers[x] == chosenNumber) {

Character Code
A 1
B 00
C 01
D 10
E 0
The professor argues that these codes store the text in less space than that used by an optimal Huffman code. Is the professor correct?
Answers
Answer:
This is not true
Explanation:
The optimal Huffman code is used to encrypt and compress text files. It uses fixed-length code or variable-length code for encryption and compression of data.
The professor's character code is similar to Huffman's variable-length coding which uses variable length od binary digits to represent the word strings. The file size of the text file above is;
= 6 x 1 + 2 x 2 + 3 x 2 + 2 x 2 + 8 x 1 = 28 bits
This would be the same for both cases.
The encrypt would be the problem as the encoded and decoding of the characters B and E may cause an error.

Answers
Answer:
This is one of the most common types of lighting. Ambient light is a soft glow that blankets your space just enough for you to function without causing a harsh glare. In photography and cinematography, ambient light is considered the "natural light" within a room. In décor, ambient light is very similar, except you create the ambient light by making the room's lighting as natural and flat as possible. While ambient light is meant to get you safely from point A-to-B, it is not ideal for working closely with things or to highlight things around your space. When used correctly, ambient light creates a fantastic environment to relax from an overly stressful day or to have a warm conversation with an old friend. Ambient lighting is often referred to as mood lighting, because this light captures the soft curves of your face and allows your pupils to dilate slightly (a physical sign of affection). Some yoga studios have even begun using the softer ambient lighting in their classes to help draw stress from the body. This is a smaller more concentrated light. You want task lighting around when you’re working. In fact, some people call it office lighting. Task lighting is meant to help you see when you’re doing projects in which you need a finer light, such as, reading, cooking, writing, sewing and many other things. Task lighting only works well when it is used as a contrasting light. For example, if you have a low lit room with a swing arm lamp turned on over your desk, the light over the desk surface will be more effective with less glare or shadow-effect than if the entire room was lit with a brighter light. Task lighting helps naturally stimulate your brain. The contrasting light allows you to be more alert and concentrated. This will help you see more details as you work, creating higher quality results. This is why many businesses choose to use task lighting in their offices.
Explanation:
Lights can perform functions such as the illumination of rooms, decorations, etc.
Light is a powerful tool that can be used in setting a particular mood or drawing attention to the products in a store. There are several types of light such as:
Ambient lighting: It is used for lighting up a room. It gives a uniform level of illumination as it creates an overview of a room. Examples include a chandelier, table lamp, track light, etc.
Task lighting: It illuminates the task that a person is carrying out. Such tasks include reading, computer work, cooking, etc.
Accent lighting: It's used to focus on a particular point of interest in order to achieve the desired effect. It is usually used to highlight an architectural feature, sculpture, or a collection of objects.
