Answer:

Behaviour

Style

Structure

Explanation:

Above are the three primary separation of concerns for a web application at client side.

Structure --> we can define the structure of the application at client side using HTML

style-->style is used to give some styling information like font,color,headings so on at client side .In general we use CSS to do this at client side

Behaviour--> it actually defines the functionality of the elements at client side like when we click button what it should do.We will use JavaScript to define the behaviours at client side

   b1 = y > x; // false  

     

   b2 = x > y; // true  

     

   cout << "b1 is = " << b1 << "\n";

Write a program that prompts the user to enter two characters and display the corresponding major and year status. The first cha
nydimaria [60]

Answer:

  1. import java.util.Scanner;  
  2. public class Main {
  3.    public static void main(String[] args) {
  4.        Scanner input = new Scanner(System.in);
  5.        System.out.print("Please enter two characters: ");
  6.        String inputStr = input.nextLine();
  7.        if(inputStr.charAt(0) == 'B' || inputStr.charAt(0) == 'b'){
  8.            System.out.println("Biology");
  9.        }
  10.        else if(inputStr.charAt(0) == 'C' || inputStr.charAt(0)== 'c'){
  11.            System.out.println("Computer Science");
  12.        }
  13.        else if(inputStr.charAt(0) == 'I' || inputStr.charAt(0) == 'i')
  14.        {
  15.            System.out.println("Information Technology and Systems");
  16.        }
  17.        else{
  18.            System.out.println("Invalid major");
  19.        }
  20.        int num = Character.getNumericValue(inputStr.charAt(1));
  21.        if(num >= 1 && num <= 4){
  22.            switch (num){
  23.                case 1:
  24.                    System.out.println("freshman");
  25.                    break;
  26.                case 2:
  27.                    System.out.println("sophomore");
  28.                    break;
  29.                case 3:
  30.                    System.out.println("junior");
  31.                    break;
  32.                case 4:
  33.                    System.out.println("senior");
  34.                    break;
  35.            }
  36.        }
  37.        else{
  38.            System.out.println("Invalid year status");
  39.        }
  40.    }
  41. }

Explanation:

The code consists of two main parts. The part 1 is to validate the input major and print out the major according to the input character (Line 10 -22). If the input character is not matched with the target letters, a message invalid major will be displayed.

The part 2 is to validate the year status to make sure it only fall within the range of 1-4  (Line 26 -45). If within the range, the program will display the year major accordingly. If not a message invalid year status will be displayed.

How do you do basic addition and subtraction in binary, octal and hex?
olasank [31]

Explanation:

The use of numerical systems arose from the need of man to improve certain mathematical calculations as time goes.

Several factors demanded the study and application of mathematical operations using decimal numbers. Among these factors, technological advancement essentially from the first experiments in the use of electronics.

There are several numeric systems, but four of them stand out: decimal, binary, octal and hexadecimal.

The decimal system is used every day in countless ways and, no doubt, is the most important number system. He has ten digits with which can form any number through the law.

Non-decimal systems such as binary, octal and hexadecimal are critical in the areas of digital and computer techniques. Through these systems is possible to perform logical combinations and working with computer programming languages. This article will show the link between the logical circuits and these numbering systems.

2 - The Binary Numbering System

The binary numbering system is composed of only two digits:

Zero (0)

One (1)

To represent zero amount using the number 0; to represent a quantity, use the digit 1.

Assuming you need to represent the number two. Which digit you can use, if there is no number 2 in that system?

We have the following response. In the decimal system, we do not have the number ten and represent the amount of ten using the digit 1 followed by the digit 0. In this case, the number 1 means that we have a group of ten and the digit 0, no drive, which means ten.

In the binary system, do likewise. For you the amount of two, we use the digit 1 followed by the digit 0. The figure 1 means that there is a group of two elements and 0, a group of any unit, thus representing the number two.

The table below helps us to understand the differences between the decimal and binary system, using this rule. The number sequence displayed to the number nine.

5

1001

2.1 - System Conversion binary to Decimal System

To better understand the conversion we use a decimal number either, for example, 356. This number means:

3 x 100 + 5 x 10 + 6 x 1 = 356

Hundred ten unit

3 x 10 � + 5 x 10 � 6 x 10 + 10 = 356

We realize that the least significant digit (6) multiplies the unit (1), the second digit (5) multiplies the ten (10) and the most significant (3) multiplies the hundred (100). The sum of these results will represent the number.

In General, the formatting rule of a number is the sum of each digit multiplied by the corresponding base (in the example, the number ten) high for an index as the positioning of the digit in the number.

In another situation, we will use a binary number, for example, the number 101. We can conclude that it is equivalent to number 5 in the decimal system. Using the concept of a number, we will convert the number to the decimal system as follows:

1 0 1

1 x 2� + 0 x 2� + 1 x 2
