For this activity, you will practice being both proactive and reactive to bugs. Both are necessary to get rid of errors in code.

Proactive:

Log in to REPL.it and open your Calculator program that you built in Unit 5.
In the index.js file, type and finish the following block of code that validates the input to make sure both are numbers (not letters or symbols):
try{
if (isNaN(…) || isNaN(…)){
throw …
}
else{
document.getElementById("answer").innerHTML = num1 + num2;
}
}
catch(e){
document.getElementById("answer")…
}

(Note: The || symbol is used in JavaScript to mean or . You can find this key to the left of the Z key if you’re using a PC or directly above the Enter key if you’re using a Mac.)
Add the finished code above to the correct place in your add() function. Make sure to delete this line since we moved it into the try block:
document.getElementById("answer").innerHTML = num1 + num2;
Paste the same code into the subtract() , multiply() , and divide() functions, making the necessary changes. Be careful with your divide() function since you already have an extra if else statement checking for a division by 0 mistake. (Hint: Cut and paste the entire if else statement inside the else block of your try statement.)
Test your program by typing in letters or symbols instead of numbers. Make sure you get the appropriate error message. (Note: The function is not supposed to check whether the text field is empty, only whether it contains non-numbers.)
When you are finished, share the link to your webpage with your teacher by clicking on the share button and copying the link.
Reactive:
The following Python program should print the sum of all the even numbers from 0 to 10 (inclusive), but it has two bugs:

x = 0
sum = 0
while x < 10:
sum = sum + x
x = x + 1
print(sum)
Complete a trace table and then write a sentence or two explaining what the errors are and how to fix them. You can choose whether to do the trace table by hand or on the computer. Turn in your trace table and explanation to your teacher.

Answer:

B innovative

Explanation:

new and better are synonymous with innovation

Answer:

The program in python is as follows:

n = int(input("n: "))

sum = 0

for i in range(2,n+1):

   if i%2 == 0:

       sum+=i

print(sum)

Explanation:

This gets input n

n = int(input("n: "))

This initializes sum to 0

sum = 0

This iterates through n

for i in range(2,n+1):

This checks if current digit is even

   if i%2 == 0:

If yes, take the sum of the digit

       sum+=i

Print the calculated even sum

print(sum)

d. IPv4 Address 192.168.0.4 is associated with the globe IPv6 address 2001:db8:0:10:0:efe

Explanation:

The adapter setting will be associated with the global IP address. When Ipconfig command is operate the IP address finds the relevant domain and then address will use a different subnet. The network will use both IPv4 and IPv6 subnets in order to execute the command.

In the tunnel adapter settings, when performing the ipconfig command, the given output line depicts: D. IPv4 Address 192.168.0.4 is associated with the global IPv6 address 2001:db8:0:10:0:efe.

A tunnel adapter can be defined as a virtual interface which is designed and developed to encapsulate packets as a form of tunnel or virtual private network (VPN) protocol while sending them over another network interface.

In Computer networking, an output line of "IPv6 Address: 2001:db8:0:10:0:efe:192.168.0.4" in the tunnel adapter settings simply means that an IPv4 Address 192.168.0.4 is associated with the global IPv6 address 2001:db8:0:10:0:efe.

Which XXX declares a student's name.

public class Student {

   XXX

   private double myGPA;  

   private int myID;

   public int getID() {

        return myID;

   }

}

Group of answer choices

a. String myName;

b. public String myName;

c. private myName;

d. private String myName;

private String myName;

To declare a student's name, the following should be noted.

i. The name of the student is of type String

ii. Since all of the instance variables (myGPA and myID) have a private access modifier, then myName (which is the variable name used to declare the student's name) should be no exception. In other words, the student's name should also have a private access.

Therefore, XXX which declares a student's name should be written as

private String myName;

Option (a) would have been a correct option if it had the private keyword

Option (b) is not the correct option because it has a public access rather than a private access.

Option (c) is not a valid syntax since, although it has a private access, the data type of the variable myName is not specified.

Option (d) is the correct option.

Solution :

Scanner scanFile = null;

try {

scanFile = new Scanner(myFile);

myAccount.withdraw(scanFile.nextDouble());

} catch (OverdrawnException oe){

System.out.println(oe.getMessage());

} finally {

if (scanFile != null){

scanFile.close();

}

The modified program in Python is as follows:

triangle_char = input('Enter a character:\n')

triangle_height = int(input('Enter triangle height:\n'))  

for i in range(triangle_height):

   print(triangle_char * (i+1))

Explanation:

This gets the character from the user

triangle_char = input('Enter a character:\n')

This gets the height of the triangle from the user

triangle_height = int(input('Enter triangle height:\n'))  

This iterates through the height

for i in range(triangle_height):

This prints extra characters up to the height of the triangle

   print(triangle_char * (i+1))

Here's the modified program that incorporates the requested changes:

python

Copy code

triangle_char = input('Enter a character:\n')

triangle_height = int(input('Enter triangle height:\n'))

print('')

for i in range(1, triangle_height + 1):

   line = triangle_char * i + ' ' * (triangle_height - i)

   print(line)

This program uses a loop to iterate from 1 to triangle_height. In each iteration, it creates a line by concatenating triangle_char repeated i times with spaces (' ') repeated (triangle_height - i) times. The resulting line is then printed.

For example, if the user enters % as the character and 5 as the height, the output will be to make sure to maintain the indentation properly in your code for it to work correctly.

Answer:

For healthy living a clean environment is crucial: The more you care about our environment, the more contaminants and toxins that have a detrimental effect on our health are polluted. Air pollution can lead, among other problems and diseases, to respiratory and cancer problems

Explanation:

Ensuring and improving the climate is an important resource for Irelanders. To safeguard against radiation and contamination damage our kin and the climate.

We have the vision:

A perfect environment to promote practical society and economy, which is sound and very secure.

Very few people are working to keep the environment clean. Although municipal authorities are responsible for making sure the environment is clean, the clean and green environment must also be supported.

Reasons Why We Should Care About the Environment

An essential part of human survival is the environment in which we live. I believe that people who don't care about the environment simply don't know how important it is for us all and how it doesn't directly affect them, which is why I want you to worry about the environment.

Earth Is Warming: We must do more to fight climate change for our children and our future. Yes, no single event trends. Yes, it is true. You can't ignore that now.

Biodiversity is essential: the diversity of plants, animals and the rest of our world is concerned with biodiversity. Habitat loss and degradation due, among other things, to human activity, climate change, and pollution could be negatively affected.

Answer:

competitive

Explanation:

An inhibitor is a substance that hinders the action of an enzyme. An inhibitor may be competitive or non competitive.

A competitive inhibitor is an inhibitor that is very similar to the substrate hence it binds to the enzyme instead of the substrate. A noncompetitive inhibitor binds to a site that is different from the active site. This site is called an allosteric site.

If we look at the experiment described in the question, the reaction rate decreases upon addition of the inhibitor. This effect is reversed by adding a large quantity of substrate.

The implication of this observation is that the enzyme and the inhibitor compete for the active site on the substrate.

Hence the inhibitor is a competitive inhibitor.

Answer: What grade work is this i would really like to know?

Explanation:

The source code, written in Java, and a sample output have been attached to this response. It contains comments explaining certain parts of the code.

A few things to note are;

(i) The Scanner class is imported to allow user's interact with the program. This is done by writing the import statement at the top of the code as follows;

import java.util.Scanner;

(ii) An object of the Scanner class is created to receive inputs from the user. The object is called input and created as follows;

Scanner input = new Scanner(System.in);

(iii) Since the user is expected to enter an integer, the nextInt() method of the Scanner object is used to receive the integer and this is saved in a variable called number. i.e

int number = input.nextInt();

(iv) A number x, is even if its remainder when divided by 2 is 0. i.e

if x % 2 = 0, then x is even. Otherwise it is odd.

The user's input received and saved in a variable called number is then checked using if and else blocks to check if it is even or not and can be written as follows;

if(number % 2 == 0){

   System.out.println(number + " is even");

}else {

   System.out.println(number + " is odd");

The program in C is as follows:

#include <stdio.h>

int main(){

   int scores[10];

   for(int i = 0; i<10;i++){

       scanf("%d", &scores[i]);    }

   int max = scores[0];

   for(int i = 0; i<10;i++){

       if(max<scores[i]){

           max = scores[i];        }    }

   for(int i = 0; i<10;i++){

       if(max==scores[i]){

           printf("%d ", scores[i]);

                   }    }

   return 0;

}

Explanation:

This declares the average scores as an integer array

  int scores[10];

The following iteration gets the average score for each student

   for(int i = 0; i<10;i++){

       scanf("%d", &scores[i]);    }

This initializes the maximum to the first index

   int max = scores[0];

This iterates through the 10 elements of the array

   for(int i = 0; i<10;i++){

This makes comparison to get the maximum

       if(max<scores[i]){

           max = scores[i];        }    }

This iterates through the 10 elements of the array

   for(int i = 0; i<10;i++){

This prints all maximum in the array

       if(max==scores[i]){

           printf("%d ", scores[i]);

                   }    }

   return 0;

Answer:

other languages are increasing in popularity

Explanation:

The simple main reason for this is that other languages are increasing in popularity. There are many open-source languages that are being optimized constantly and upgraded with new features. The ability for these languages to perform many tasks better than Java makes it the obvious choice when a developer is choosing a language to develop their program on. Two of these languages are Javascript and Python. Both can do everything that Java can and with less code, faster, and cleaner.

Answer:

Trends in the workplace are constantly evolving and the latest trends are tough to maintain. Ten years ago, employers did not care about open businesses, advantages like ping pong tables and lunches on Fridays, or standing desks and unbounded time off. As times change, however, companies have to adopt trends to increase productivity and employee involvement in the workplace.

Explanation:

There are several features in the global economy, for example:

It is selfless teamwork. It concentrates on the ultimate objective. Teamwork is based on the idea that the whole exceeds the sum of its components. It's the traditional idea of "one plus one is equal to three." Personalities and the ability to create personal conflicts are different. However, the differences between the members of the team become strengths and goals, if the whole team focuses on doing great work.

TECHNOLOGY: The skills, methods, and processes used to achieve objectives are technology. The technology to use is:

Knowledge of how to do things maybe technology. Embedding machines are examples. This enables others to use the machines without knowing how they function. By taking something, changing it, and producing results, the technological system uses the technology. They are also known as systems of technology.

Developing and using fundamental tools is the simplest form of technology. The discovery of fire and the Revolution made food more readily available. Additional inventions such as the ship and the wheel have helped people and themselves to transport goods. IT, like the printer, the phone, and the internet, has led to Globalization.

Diversity is a range of differences in the human race, ethnicity, sexuality, age, social class, physical capacity or attributes, religious or ethical values systems, nationality, and political faith.

Inclusion is participation and empowerment, which recognize everybody's inherent worth and dignity. An included university supports and promotes the sense of belonging; respects its members' talents, beliefs, backgrounds, and livelihoods. They respect and practice them.
