Determine the binary encoding for a system that uses two’s complement of the base-10
quantities negative six and six for a digital system where all binary numbers are represented by four bits, one where all numbers are represented by eight bits (one byte).

Answer:

4 bits:

6 = 0110

-6 = 1010

8 bits:

6 = 00000110

-6 = 11111010

Explanation:

2's complement is easier to implement, because it only has one representation of 0 and starts counting backwards from the highest number you can represent with the available bits.

e.g.,

7 = 0111

6 = 0110

5 = 0101

4 = 0100

3 = 0011

2 = 0010

1 = 0001

0 = 0000

-1 = 1111

-2 = 1110

-3 = 1101

-4 = 1100

-5 = 1011

-6 = 1010

For 4 bits:

For 8 bits (1 byte):

Binary encoding can be defined as a standard technique that is designed and developed to convert data in plain text (source alphabets) to a form that is easily used by different operating systems (OS), especially through the use of a binary digit (bit) or two-symbol system.

In Computer programming, two's complement of base-10 is generally easier to implement because it has a single representation of 0 only.

Decimal      Two’s Complement      Decimal      Two’s Complement

    0                       0000                        0                        0000

    1                       1111 1111                       -1                      0000 0001

    2                      1111 1110                      -2                    0000 0010

    3                      1111 1101                      -3                    0000 0011

    4                      1111 1100                     -4                    0000 0100

    5                      1111 1011                      -5                    0000 0101

    6                      1111 1010                     -6                    0000 0110

    7                      1111 1001                     -7                    0000 0111

    8                      1111 1000                    -8                    0000 1000

For 4 bits:

-6 = 0110

6 = 1010

For 8 bits (1 byte):

-6 = 0000 + 0110 = 00000110

6 = 1111 + 1010 = 11111010

Write a program to calculate the angle of incidence (in degrees) of a light ray in Region 2 given the angle of incidence in Region 1 and the indices of refraction n1 and n2. (Note: If n2>n1, then for some angles 1, Equation 2 will have no real solution because the absolute value of the quantity will be greater than 1. When this occurs, all light is reflected back into Region 1, and no light passes into Region 2 at all. Your program must be able to recognize and properly handle this condition.) The program should also create a plot showing the incident ray, the boundary between the two regions, and the refracted ray on the other side of the boundary. Test your program by running it for the following two cases: (a) n1= 1.0, n2 = 1.7, and 1= 45°. (b) n1 = 1.7, n2 = 1.0; and 1= 45°

#Python: The given program reads a list of single-word first names and ages (ending with -1), and outputs that list with the age incremented. The program fails and throws an exception if the second input on a line is a string rather than an integer. At FIXME in the code, add try and except blocks to catch the ValueError exception and output 0 for the age.

Ex: If the input is:

Lee 18
Lua 21
Mary Beth 19

-1
then the output is:

Lua 22
Mary 0
Stu 34

Create a class RightTriangle which implements the API exactly as described in the following JavadocLinks to an external site..

Don't forget - you will need to use the Pythagorean theorem (Links to an external site.) to find the hypotenuse (and therefore the perimeter) of a right triangle. You can find the area of a right triangle by multiplying the base and height together, then dividing this product by 2.

Use the runner_RightTriangle file to test the methods in your class; do not add a main method to your RightTriangle class.

Hint 1 - Javadoc only shows public methods, variables and constructors. You will need to add some private member variables to your RightTriangle class to store the necessary information. Think carefully about what information actually needs to be stored and how this will need to be updated when methods change the state of a RightTriangle object.

Hint 2 - As in the previous lesson's exercise it's helpful to add your method/constructor headers and any dummy returns needed before implementing each one properly. This will allow you to test your code using the runner class as you go along.

This is the runner code:

import java.util.Scanner;

public class runner_RightTriangle{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
RightTriangle t = new RightTriangle();
String instruction = "";
while(!instruction.equals("q")){
System.out.println("Type the name of the method to test. Type c to construct a new triangle, q to quit.");
instruction = scan.nextLine();
if(instruction.equals("getArea")){
System.out.println(t.getArea());
}
else if(instruction.equals("getBase")){
System.out.println(t.getBase());
}
else if(instruction.equals("getHeight")){
System.out.println(t.getHeight());
}
else if(instruction.equals("getHypotenuse")){
System.out.println(t.getHypotenuse());
}

else if(instruction.equals("getPerimeter")){
System.out.println(t.getPerimeter());
}
else if(instruction.equals("toString")){
System.out.println(t);
}
else if(instruction.equals("setBase")){
System.out.println("Enter parameter value:");
double arg = scan.nextDouble();
t.setBase(arg);
scan.nextLine();
}
else if(instruction.equals("setHeight")){
System.out.println("Enter parameter value:");
double arg = scan.nextDouble();
t.setHeight(arg);
scan.nextLine();
}
else if(instruction.equals("equals")){
System.out.println("Enter base and height:");
double bs = scan.nextDouble();
double ht = scan.nextDouble();
RightTriangle tOther = new RightTriangle(bs, ht);
System.out.println(t.equals(tOther));
scan.nextLine();
}
else if(instruction.equals("c")){
System.out.println("Enter base and height:");
double bs = scan.nextDouble();
double ht = scan.nextDouble();
t = new RightTriangle(bs, ht);
scan.nextLine();
}
else if(!instruction.equals("q")){
System.out.println("Not recognized.");
}
}
}
}

My code so far:

class RightTriangle{
private double base;
private double height;
public RightTriangle(){
base = 1.0;
height = 1.0;
}
public RightTriangle(double ds, double ht){
base=ds;
height=ht;
}
public boolean equals​(RightTriangle other){
if(base==other.base && height==other.height ){
return true;
}
else
{
return false;
}
}
public double getArea()
{
return (base*height)/2;
}
public double getBase(){
return base;
}
public double getHeight()
{
return height;
}
public double getHypotenuse()
{
return Math.sqrt((base*base)+(height*height));
}
public double getPerimeter()
{
return base+height+Math.sqrt((base*base)+(height*height));
}
void setBase (double bs)
{
if(bs==0){
System.exit(0);
}
else{
base=bs;
}
}
public void setHeight(double ht){
if(ht==0){
System.exit(0);
}
height=ht;
}
public java.lang.String toString()
{
return "base: "+base+" hegiht: "+height+" hypothesis: "+ Math.sqrt((base*base)+(height*height));
}

}

MY CODE SAYS THAT THE setHeight and setBase and toString METHODS ARE INCORRECT.

An array of integers can be assigned to a memory address in the ...
An array of integers can be assigned to a memory address in the .datanumbers
section of a MIPS assembly language program as show below. Here the length of the array is stored first, and then the elements of the array next.

Implement a MIPS assembly language program to perform the functionality of the following C program and print the updated array content, by listing each integer in it.

It should ask a user to enter three integers, a starting index, an ending index, and an integer to use for a comparison. It should examine only the elements in the array located from the entered starting index, to the entered ending index to check if each of them is greater the last entered integer, then if it is, subtract 3*the last entered integer to each such element in the array.

For instance, if a user enters 2, enters 9, then enters 3, then the output will be the following:

45

-6

14

-7

6

-17

2

-4

14

-26

2

19





i.e., the numbers that are located between the index 2 and 9 are examined to see if each of them is greater than the last entered number (3 in this case),

then each of such element is subtracted with 3 times that number (3 in this case) if it is.

If the entered ending index is larger than 11, then the program should exam elements in the array until the end, and if the entered starting index is less than 0, then it should start examining elements from the first one in the array.

.data

numbers_len: .word 12

numbers: .word 45, -6, 23, -7, 15, -17, 11, -4, 23, -26, 2, 19}





The following shows how it looks like in a C program:


int numbers[12] = {45, -6, 23, -7, 15, -17, 11, -4, 23, -26, 2, 19};

int startIndex, endIndex, num1;
int j;

printf("Enter a starting index:n");

//read an integer from a user input and store it in startIndex
scanf("%d", &startIndex);


printf("Enter an ending index:n");

//read an integer from a user input and store it in endIndex
scanf("%d", &endIndex);

printf("Enter an integer:n");

//read an integer from a user input and store it in num1
scanf("%d", &num1);

if (startIndex < 0)
startIndex = 0;


for (j = startIndex; j <= endIndex && j < 12; j = j+1)
{
if (numbers[j] > num1)
{
numbers[j] = numbers[j] - (3 * num1);
}
}


printf("Result Array Content:n");
for (j = 0; j < 12; j = j+1)
{
printf("%dn", numbers[j]);
}




The following is a sample output (user input is in bold):

Enter a starting index:

2

Enter an ending index:

9

Enter an integer:

3

Result Array Content:

45

-6

14

-7

6

-17

2

-4

14

-26

2

19

Please make sure it can output like the sample above
