Answer:
A Prototype
Explanation:
Prototype: It is an early sample, model, or release of a product built by the programmer to test a concept or process and that will how the final product will look like.
Answer:
The correct word for the blank space is: prototype.
Explanation:
In computer science, a prototype is built to test if theoretical propositions can be translated into factual systems. The prototype is the draft of what the final software could give and include core features only. Designing prototypes is an opportunity for the programmers because the basic layout could spot unexpected failures that could or could not be corrected.
Using basic programming (for loops, while loops, and if statements), write two MATLAB functions, both taking as input:
- dimension n;
- n x n matrix A;
- n x n matrix B;
-n × 1 vector x.
Have the first function compute ABx through (AB)x and the second compute ABx through A(Bx). Have both output:
- the number of flops used.
(a) Print out or write out the first function.
(b) Print out or write out the second function.
(c) Apply both your functions to the case with random matrices and vectors for n = 100 and print out or write out the results. Do the same for 200 x 200, 400 x 400, and 800 x 800. Which approach of computing ABx is faster?
Answer:
For n = 100
(AB)x: 10100A(Bx): 200For n = 200
(AB)x: 40200A(Bx): 400For n = 400
(AB)x: 160400A(Bx): 800For n = 800
(AB)x: 640800A(Bx): 1600The faster approach is A(Bx)
Explanation step by step functions:
A(Bx) is faster because requires fewer interactions to find a result: for (AB)x you have (n*n)+n interactions while for A(Bx) you have n+n, to understand why please see the step by step:
a) Function for (AB)x:
function loopcount1 = FirstAB(A,B,x)
n = size(A)(1);
AB = zeros(n,n);
ABx = zeros(n,1);
loopcount1 = 0;
for i = 1:n
for j = 1:n
AB(i,j) = A(i,:)*B(:,j);
loopcount1 += 1;
end
end
for k = 1:n
ABx(k) = AB(k,:)*x;
loopcount1 += 1;
end
end
b) Function for A(Bx):
function loopcount2 = FirstBx(A,B,x)
n = size(A)(1);
Bx = zeros(n,1);
ABx = zeros(n,1);
loopcount2 = 0;
for i = 1:n
Bx(i) = B(i,:)*x;
loopcount2 += 1;
end
for j = 1:n
ABx(j) = A(j,:)*Bx;
loopcount2 += 1;
end
end
In this exercise we want to use computer and python knowledge to write the code correctly, so it is necessary to add the following to the informed code:
The correct code that corresponds to the question informed is attached in the photo and we can notice that the faster approach is A(Bx).
So knowing that the information given in the text is that;
For n = 100:
(AB)x: 10100 A(Bx): 200For n = 200:
(AB)x: 40200 A(Bx): 400For n = 400:
(AB)x: 160400 A(Bx): 800For n = 800:
(AB)x: 640800 A(Bx): 1600A(Bx) exist faster cause demand hardly any interplay to find a result: for (AB)x you bear (n*n)+n interplay while for A(Bx) you bear n+n, so we have that:
a)Watching the function for (AB)x:
function loopcount1 = FirstAB(A,B,x)
n = size(A)(1);
AB = zeros(n,n);
ABx = zeros(n,1);
loopcount1 = 0;
for i = 1:n
for j = 1:n
AB(i,j) = A(i,:)*B(:,j);
loopcount1 += 1;
end
end
for k = 1:n
ABx(k) = AB(k,:)*x;
loopcount1 += 1;
end
end
b) Watching the function for A(Bx):
function loopcount2 = FirstBx(A,B,x)
n = size(A)(1);
Bx = zeros(n,1);
ABx = zeros(n,1);
loopcount2 = 0;
for i = 1:n
Bx(i) = B(i,:)*x;
loopcount2 += 1;
end
for j = 1:n
ABx(j) = A(j,:)*Bx;
loopcount2 += 1;
end
end

c. continuous partial attention
d. none of the choices are correct
Answer: is Option B.
B). Multi tasking: A person capability to carry out more than one task at the same time is called multitasking. Person performing more than one task at the same time is nearly impossible and it's hard for him to focus on each and every detail, thus leading to scatter attention among numbers of things at a time resulting in inaccuracy and greater numbers of fault in final result.
Explanation of other points:
A). Attention: is defined as performing tasks with special care and concentration.
C). Continuous partial attention: Under this category people perform tasks by concentrating on different sources to fetch information by only considering the most valid information among all information. people who use this technique to gather information works superficially concentrating on the relevant information out of numerous sources in a short period of thinking process.

Which of the following is required for counter-controlled repetition?
A. a boolean
B. a method
C. a condition
D. All of the above
Counter-controlled repetition requires a condition to determine when the loop should stop, involving initializing a counter, setting a condition for it, and updating the counter within the loop. No boolean or method is strictly required, just the condition.
Explanation:The question asks which of the following is required for counter-controlled repetition. The correct answer is C. a condition. In computer programming, counter-controlled repetition requires a condition to determine when the repetition should stop. This involves initializing a counter to a starting value, setting a condition for the counter (such as counter < 10), and updating the counter within the loop (often incrementing or decrementing). This loop continues to execute as long as the condition evaluates to true.
For example, in a for loop, you might see something like for(int i = 0; i < 10; i++), where i is the counter, i < 10 is the condition that must be true for the loop to continue, and i++ updates the counter. No boolean or method is strictly required for this process, just the condition that guides the repetition.

Uppercase lettersLowercase lettersdigits (0 through 9)special characters like @#$%^&*minimum length of 8Passwords should not contain:
user's name or surnamebirth year/datenot similar to previous passwordaccount/identity numberA data file "parttolerance.dat" stores on one line, a part number, and the minimum and maximum values for the valid range that the part could weigh. Write a script "parttol" that will read these values from the file, prompt the user for a weight, and print whether or not that weight is within range. For example, IF the file stores the following:>> type parttolerance.dat123 44.205 44.287Here might be examples of executing the script:>> parttolEnter the part weight: 44.33The part 123 is not in range>> parttolEnter the part weight: 44.25The part 123 is within range
Final answer:
The script 'parttol' reads a data file with part numbers and weight tolerances, prompts for a weight input, and assesses if it's within range, providing feedback on part validity.
Explanation:
The question involves writing a script parttol for reading a data file named parttolerance.dat which contains part numbers and their respective weight tolerance ranges. The script should then prompt the user for a weight input and determine if that weight is within the range specified for a part number.
Here's a pseudocode outline for the parttol script:
Open and read the contents of parttolerance.dat.Extract the part number, minimum, and maximum weight values.Prompt the user to enter a weight.Check if the entered weight is within the range.Print a message indicating whether the part is within range.The execution of this script provides feedback to the user about the validity of the part's weight, thereby ensuring quality control in a manufacturing or engineering context.
Do you believe that OOP should be phased out and we should start working on some alternative(s)? Provide your answer with Yes or No.
Give your opinion with two solid reasons to support your answer.
Answer:
I don't think so. In today's computer era, many different solution directions exist for any given problem. Where OOP used to be the doctrine of choice, now you would consider it only when the problem at hand fits an object-oriented solution.
Reason 1: When your problem can be decomposed in many different classes with each many instances, that expose complex interactions, then an OO modeling is justified. These problems typically produce messy results in other paradigms.
Reason 2: The use of OO design patterns provides a standardized approach to problems, making a solution understandable not only for the creator, but also for the maintainer of code. There are many OO design patterns.
We will pass in 2 values, X and Y. You should calculate XY XY and output only the final result. You will probably know that XY XY can be calculated as X times itself Y times. # Get X and Y from the command line:import sysX= int(sys.argv[1])Y= int(sys.argv[2])# Your code goes here
Answer:
import sys
# The value of the second argument is assigned to X
x = int(sys.argv[1])
# The value of the third argument is assigned to Y
y = int(sys.argv[2])
# The result of multiplication of x and y is assigned to 'result'
result = x * y
#The value of the result is displayed to the user
print("The result of multiplying ", x, "and ", y, "is", result)
Explanation:
First we import sys which allow us to read the argument passed when running the program. The argument is number starting from index 0; the name of the python file been executed is sys.argv[0] which is the first argument. The second argument is sys.argv[1] and the third argument is sys.argv[2].
The attached file is named multplyxy (it wasn't saved as py file because the platform doesn't recognise py file); we can execute it by running: python3 multiplyxy.py 10 23
where x will be 10 and y will be 23.
To run the attached file; it content must be saved as a py file: multiplyxy.py

printf ("\n%u%u%u\n", &m.num, m.msgi, m3 m2 m.msg2 );
printf ("\n%d %s %s", m.num,m.msgi, m.msg2);
return 0;
}
Answer:
Output: 2004 2008 2058
Explanation:
In the first printf command it will print the address of the variables num, msg1, msg2. And in the second printf command it will print the values of the variables num, msg1, msg2. As the address of the structure is 2004 And the size of the integer is 4 byte so size will increase with 4 bytes and the size of character is 1 byte so it will increase by 1*50= 50 bytes.
Hence, the output is 2004 2008 2058
What is the output of the following query? SELECT INSERT ('Knowledgeable', 5, 6, 'SUPER');
Answer:
The above query gives an error.
Explanation:
The query gives an error because is not the correct syntax of the select or inserts query.The syntax of the select query is as follows: "select Attributes_1_name, Attributes_2_name,...., Attributes_n_name from table_name;".The syntax of the insert query is : "insert into table_name (column_1_name, column_2_name,...,column_n_name) values (column_1_value, column_2_value,...,column_n_value);".The syntax of the insert and select query is : "insert into table_name (select Attributes_1_name, Attributes_2_name,...., Attributes_n_name from table_name);".But the above query does not satisfy any property which is defined above. Hence it gives a compile-time error.What is the value of vals[4][1]? double[][] vals = {{1.1, 1.3, 1.5}, {3.1, 3.3, 3.5}, {5.1, 5.3, 5.5}, {7.1, 7.3, 7.5}};
Answer:
When the user concludes the value of "vals[4][1]", then it will give an exception of "ArrayIndexOutOfBoundsException".
Explanation:
It is because the size of the above array is [4*3] which takes the starting index at [0][0] and ending index at [3][2]. It is because the array index value starts from 0 and ends in (s-1). When the double dimension array size is [5][5], then it will conclude the value of [4][1].The above array have following index which value can be calculated :-- [0][0],[0][1],[0][2],[1][0], [1][1],[1][2], [2][0], [2][1], [2][2],[3][0],[3][1] and [3][2].Which type of attack modifies the fields that contain the different characteristics of the data that is being transmitted?
