Answer:
(A) Assembly language should be avoided for general application development for the following reasons:
i. It is difficult to write assembly language codes. It does not contain many tools and in-built functions to help with the development of these applications.
ii. Since general application development requires that the application be machine independent, writing such applications in assembly language (which is a low level, machine dependent language) might be a pain as it would require that the writer have sufficient knowledge of hardware and operating systems.
(B) The following are the circumstances where assembly language should be used:
i. Assembly languages are low level languages that are very close to machine languages that the machine or processor understands. Therefore, when writing codes for programs that should directly communicate with the processor, assembly language should be used.
ii. Since assembly language codes are machine dependent, when there is a need to write applications for target machines, they should be used.
iii. If there is a need to have very great control of certain features of your application and resources to be consumed such as amount of RAM, clock speed e.t.c, assembly languages are a great tool.
(C) Some of the advantages of compiled language over an interpreted language are:
i. Compiled languages are way faster than interpreted languages because the compiled languages are converted directly into native machine codes that are easy for the processor to execute. Put in a better way, with compiled languages, codes are compiled altogether before execution and therefore reduces the overhead caused at run time. Interpreted languages on the other hand executes codes line after line thereby increasing the overhead at run time.
ii. Since codes are compiled first before execution in compiled languages, nice and powerful optimizations can be applied during the compilation stage.
(D) Interpreted languages could be chosen over compiled languages for the following reasons:
i. Interpreted languages are much more flexible and easier to implement than compiled languages as writing good compilers is not easy.
ii. Since interpreters don't need to convert first to intermediary codes as they execute these codes themselves, programs built with interpreters tend to be platform independent.

Answer:
True
Explanation:
You trained a binary classifier model which gives very high accuracy on thetraining data, but much lower accuracy on validation data. The following maybe true:
a. This is an instance of overfitting.
b. This is an instance of underfitting.
c. The training was not well regularized.
d. The training and testing examples are sampled from different distributions.
Answer:
a. This is an instance of overfitting.
Explanation:
In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.
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 String myName; public String myName; private myName; private String myName;
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;
Answer:private String myName;
Explanation: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.

Write a C++ program to accept a 5 digit integer and to validate the input based on the following rules.
Rules
1) The input number is divisible by 2. 2) The sum of the first two digits is less than last two digits. if the input number satisfies all the rules, the system prints valid and invalid, otherwise,
Example 1:
Enter a value: 11222
Output: Input number is valid
Example 2:
Enter a value: 1234
Output: Input number is invalid
Answer:
#include <iostream>
#include <string>
#include <regex>
using namespace std;
int main()
{
cout << "Enter a 5-digit number: ";
string number;
cin >> number;
bool valid = regex_search(number, regex("^\\d{4}[02468]$"));
if (valid) {
valid = stoi(number.substr(0, 1)) + stoi(number.substr(1, 1))
< stoi(number.substr(3, 1)) + stoi(number.substr(4, 1));
}
cout << number << (valid ? " is valid" : " is invalid");
}
Explanation:
Regular expressions can do all of your checking except for the sum of digits check. The checks are i.m.o. easiest if you don't treat the input as a number, but as a string with digits in it.
The regex means:
^ start of string
\d{4} exactly 4 digits
[02468] one of 0, 2, 4, 6 or 8 (this is what makes it even)
$ end of string
Consider a file system using the indexed allocation. The block size is 512 bytes and the pointer to a block takes 2 bytes. The largest file size that a one level indexed allocation method could handle is ___________ KB. Recall that 1KB is equal to 210 bytes. Answer -1 if there is no limit based on the provided information.
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.

(1 pt) (2) Modify the program to use a loop to output a right triangle of height triangle_height. The first line will have one user-specified character, such as % or* Each subsequent line will have one additional user-specified character until the number in the triangle's base reaches triangle_height. Output a space after each user-specified character, including a line's last user-specified character. (2 pts) Example output for triangle_char = % and triangle_height = 5: Enter a character: Enter triangle height: 5 273334.1408726 LAB ACTIVITY 16.6.1: LAB: Warm up: Drawing a right triangle 0/3 main.py Load default template... 1 triangle_char - input('Enter a character:\n') 2 triangle_height = int(input('Enter triangle height:\n')) 3 print('') 4 5 print ('*') 6 print ("**') 7 print ("***') 8
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.

If the code for JAVA is LCXC, what is the code for BASIC?
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
J = L because L comes after J and KA = C because C comes after A and BV = X because X comes after V and UA = C because C comes after A and BSimilarly for BASIC;
B = D because D comes after B and CA = C because C comes after A and BS = U because U comes after S and TI = K because K comes after I and JC = E because E comes after C and DThus, finally the code for BASIC is DCUKE

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.
