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.

Explanation:

Communication are happen when 2 people are response each other

It is not true that when you are listening to another person speak, you can avoid sending any messages by not speaking and not making eye contact. The correct option is 4.

The process of communicating information, concepts, ideas, or sentiments between two or more people through a variety of means and channels, including verbal and nonverbal communication, is referred to as communication.

It is a myth that you may avoid transmitting any messages when you are listening to someone else speak by remaining silent and avoiding eye contact.

Your body language and nonverbal communication, such as your facial expressions and eye contact, can still convey information to the speaker even if you are not replying verbally or establishing eye contact.

Hence, even if a message is unintended or nonverbal, all types of communication entail sending and receiving messages.

Thus, the correct option is 4.

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.

Answer:

-- While mainly a readability feature, we can technically use Enum to do things like spoof a Boolean type in C allowing us some level of functionality.

-- Enums are great for representing states and other common constants like colors.

-- Enums let us specifically value each constant we create.

Explanation:

Enums is a part of a programming language which helps a developer or a programmer to defined a set of the named constants. Using the enums will help in making it easier to document the intent and also to create set of distinct cases.

Option 1 is applicable as in the Boolean there are only TRUE and FALSE values. By using enum one can add more state like that of being difficult or normal or easy.

Option 4 is applicable because enums are used to represent various states and also other constants.

Option 5 is also applicable they allow the developer to create each value constant.

Answer:

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:

As compared to new multiplexing techniques, older techniques like FDM frequency-division multiplexing (FDM) may be a technique by which the entire bandwidth available during a communication medium is split into a series of non-overlapping frequency sub-bands, each of which is employed to hold a separate signal.

Explanation:

Especially used for Radio and tv Broadcasting and TDM ( Time-division multiplexing (TDM) may be a method of transmitting and receiving independent signals over a standard signal path by means of synchronized switches at each end of the cable in order that each signal appears on the road only a fraction of your time in an alternating pattern, especially used for telegraphy) are simple; they'll be suffering from noise and their transmission speeds are high. New techniques are far more complex, they will be suffering from more noise and transmission speeds are very high as compared to older techniques.

Answer:

DCUKE

Explanation:

Given that,

Code for JAVA = LCXC

To find,

Code for BASIC = ?

As we observe the pattern,

In "JAVA", every letter moved two-letter forward in their alphabetical order or we can say that every third alphabet of the given letter is used to make the code:

J + 2 = L

A + 2 = C

V + 2 = X

A + 2 = C

Similarly,

B + 2 = D

A + 2  = C

S + 2 = U

I + 2  = K

C + 2 = E

Thus, DCUKE is the code for BASIC.

The code for BASIC given the code for JAVA is; DCUKE

We are given the code for JAVA as LCXC

From that code for "JAVA", we see that every letter is moved forward two letters in their alphabetical order. This means

Similarly for BASIC;

Thus, finally the code for BASIC is DCUKE

Answer:

128 KB      

Explanation:

Given data :

The block size = 512 bytes

Block pointer size = 2 bytes

In an indexed allocation, a special block named Index Block contains all the pointers to the blocks that the file had occupied.

Therefore, the maximum number of block pointer in 1 block :

[tex]$=\frac{\text{block size}}{\text{pointer size}}$[/tex]

[tex]$=\frac{512}{2}$[/tex]

= 256

Thus, a block can hold maximum 256 pointers.

It is given the level of indexing is one. So,

Maximum size of the file =  maximum number of block pointers in 1 file x block size

                                          = 256 x 512

                                          [tex]$=2^8 \times 2^9$[/tex]

                                          [tex]$=2^{8+9}$[/tex]

                                           [tex]$=2^{17}$[/tex]

                                          [tex]$=2^7 \times 2^{10}$[/tex]

                                          [tex]$=128 \times 2^{10}$[/tex]

                                          = 128 KB   (∵ 1 KB = [tex]2^{10} \ B[/tex] )

Therefore, the largest file that 1 level if indexed allocation method can handle is 128 KB.
