What are the advantages and disadvantages of UTF-8 compared to ASCII?

Answer:

can't say without seeing more code

Explanation:

In the function calling, we pass the name of array, variable and direct value as well.

for example:

int y=3;

int x[] = {1,2,3,4};

fun(y,x);

so, we can't tell which is variable and which is array, without seeing the rest of code.

we can tell by seeing the initializing variable and function declaration or create function.

Answer:    C. Employer-paid insurance

Explanation:  Employees can receive benefits i.e. financial payments in two ways, direct and indirect payments. Direct financial payments are all those paid directly by the employer to the employee, which means the employee can use those payments immediately after payment, such as wages, salaries, various bonuses, commissions, etc. Indirect benefits are all those paid by the employer to an employee from which the employee will benefit during or after a fixed period of time. These are, for example, life, health, so all kinds of insurance, paid holidays, pension funds, etc.

Answer: True

Explanation:

In shielded twisted pair (STP) we have two wires which are twisted together and they have a shielding layer outside them which helps them to avoid interference from outside noise. STP thus having the advantage with an additional layer of shield covering the two wires together makes them more durable compared to unshielded twisted pair.

Answer:

private int[ ] testMethod ( int x )

Explanation:

Before going to the reason first understand the syntax of declare the function.

Syntax:

Access_modifier return_type name (argument_1, argument_2,...);

Access_modifier is used for making the restriction to access the values.

it is public, private and protected.

Return_type:  it is used to define return type of the function.

it can be int, float, double.

In the question:

Option 1:  private array testMethod ( int x )

it is not valid because array is not valid return type.

Option 2: private int[ ] testMethod ( int x )

int[ ]  denotes the integer array. so, the function return the integer array.

Option 3: private double[5] testMethod ( int x )

it is not valid because double[5] is not valid return type. we cannot enter the size of the array.

if we replace double[5] to double[ ], then it valid and the function return double type array.

Option 4: private double testMethod[ ] ( int x )

it return type is double. So, it return the decimal value but not array.

Therefore, the correct option is (b).

Answer:

The first graph in the picture describes a relation that is (a) Reflexive, transitive, and anti-symmetric.

Because a, b, c, d all are related to itself, so reflexive.

where (a, b) and (b, d) are in the relation, (a,d) is in the relation,    

for (c,a) and (a,b) there is (c,b).

so it's transitive.

for all a,b in the relation, (a,b) there is no (b,a) with a ≠b.

The second graph in the picture describes a relation that is (b) Reflexive, transitive, and neither symmetric nor anti-symmetric.

Because a, b, c, d all are related to itself, so reflexive.

where (a, b) and (b, a) are in the relation, (a,a) is in the relation,                                                    

where (c, d) and (d, d) are in the relation, (c,d) is in the relation,                                                    

so it's transitive.

Because, (a,b) and (b.a) are there, but for (c,d) there is no (d,c) in relation.

So, the relation is not symmetric.

(a,b) and (b,a) is in relation but, a≠b, so not anti symmetric.

Explanation:

For all a in a set,  if (a,a) in a relation then the relation is reflexive.

For all (a,b) in relation R, if (b,a) is also in R, then R is symmetric.

For all (a,b), (b,c) in relation R, if (a,c) is also in R, then R is transitive.

For all (a,b), (b,a) in R, a = b,  then R is an anti- symmetric relation.

True.

C. Bidirectional

Explanation:

If we want to access elements at an any random offset position then we can use random access iterators.They use the functionality 'as relative to the element they point to' like pointers.Random access iterators are Bidirectional iterators that can randomly process elements,pointer types are also random-access iterators.

Answer:

Global variables:

1. It is declare outside of all functions.

2. Cannot be declare the two global variable with same name.

3. It can be used in any where in the program, the is no problem with scope.

Local variables:

1. It is declare inside the functions.

2. Can be declare the two or more local variable with same name in the different functions.

3. It is available until that functions are executed.

Explanation:

Global variables are declare outside of all function,, we can access that variable anywhere in the program

for example:

int num = 10;

int main(){

statement;

fun(){

statement;

}

}

The variable is outside of all functions. So, it is a global variable.

It is not declare in the function or block, this is reason it has no problem with availability. it is available until the program is executed.

Other side, local variable is declare in the function.

for example:

int main(){

int num = 10;

statement;

fun(){

int num = 10;

statement;

}

}

Here, the  variable num is local variable and it can be more than one time with same name but in the different function.

it is available untill that function executed.

Answer:

Explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

This depends on the company, but some companies will accept poor quality as long as the product works and provides them faster innovation. This will happen especially if a company knows or has an idea that a competitor is working on a similar product.

Another big reason why a company might accept poor quality in order to release a product is money. Sometimes a company does not have the budget to continue the project, therefore they release it usually in Early Access. This allows them to start making some money on the project while they continue to work on it.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

In this exercise, we are analyzing the context in which we have the quality of technological products linked to monetary value, as follows:

We know that some companies are focused on having a worse quality as long as they make a quick profit, as the consumer is not a priority.

When it comes to Price or Quality, many entrepreneurs most of the time have a false perception that the cheaper a product they tend to offer to the consumer, the greater the chances of success.

We must take into account that the option of a lower quality is often linked to the budget that a company may have.

Answer:

5KHz

Explanation:

The formula for calculating the output frequency when the input frequency and the number of flip-flops are given.

[tex]out put Frequency = \frac{in put frequency}{2^{N}}[/tex]

here, N is the number of filp-flops.

Note: The input frequency must be in Hz.

first convert given input frequency (MHz) into HZ.

[tex]in put frequency = 20.48 *10^{6}Hz[/tex]

apply the formula:

[tex]out put Frequency = \frac{20.48*10^{6}}{2^{12}}[/tex]

which comes out to be 5000Hz or 5KHz.

Answer:

b. Associativity

Explanation:

Associativity specifies the order in which operators are processed vis a vis operands/values in an expression. For example: Consider the expression: a + b + c. Here a + b is evaluated first before adding the result with c as the '+' operator is left associative. The default associativity can also be overridden by the use of parentheses. For example a + (b + c) . In this case b+c will be evaluated first.

Yes, an expression tag contains a scripting language expression that is evaluated. As, expression tag is used to display the output of the data in the generated page. If data is placed in expression tag then, it prints on the output stream and then it automatically convert data into the string and the output are displayed.

Answer: The query to delete rows for the given scenario is  

DELETE

FROM Review

WHERE Id < 100 OR Id = 100;

Explanation:

In SQL, the table can be removed using either DROP, TRUNCATE or DELETE commands.

DROP command is used to delete the whole structure of the table. The general syntax is given below.

DROP TABLE table_name;

After this command, the whole structure of the specified table will be deleted. This table will have to be created again in order to use it and put data in this table.

SELECT *

FROM table_name;

This command when executed after the DROP command, will show an error.

This command can be used to drop database objects like constraints, index and the others.

The TRUNCATE command removes all the rows from a table. The structure of the table remains intact and data can be put again in this table.

This command only removes the data currently present in the table.

The general syntax is given below.

TRUNCATE TABLE table_name;

The command below will compile but it will not return any rows.

SELECT *

FROM table_name;

Alternatively, DELETE keyword is used to drop only the rows from a given table.

The general syntax for deleting rows from a table is given below.

DELETE

FROM table_name

WHERE [condition];

The WHERE clause is optional in a DELETE query.

SELECT *

FROM table_name;

The above command will compile and return rows if rows are present in the table other than the deleted rows.

The table used in the given query is Review table. We assume that Id is the primary key for the Review table. The query becomes

DELETE

FROM Review;

The condition for this deletion is that Id should be less than or equal to 100. The final query is written as

DELETE

FROM Review

WHERE Id < 100 OR Id = 100;

Answer:

A. vecList.erase(position)

Explanation:

Assuming vecList is a vector container, the expression vecList.erase(position) deletes all elements from the container.

Assuming vecList is a vector container, the expression vecList.erase(position) deletes all elements from the container. Thus, the correct option for this question is A.

A vector container may be defined as a type of sequence that significantly represents arrays that can change in size. They significantly utilize contiguous storage locations for their elements. This means that their elements can also be accessed using offsets on regular pointers to their elements, and just as efficiently as in arrays.

According to the context of this question, vecList.erase(position) is the tool of the vector container in order to delete all sorts of elements that have been expressed by the vector container.

Therefore, the expression vecList.erase(position) deletes all elements from the container. Thus, the correct option for this question is A.

Answer:

A. Lookup

Explanation:

You would use the Lookup field to store a value from another table.

1.Students at front rows will have to sit attentive and have to concentrate on the lecture being delivered,thus their knowledge about the lecture is way better than the students at back rows.

2. Front row students are more in line with the teacher and they have much better concepts regarding the lecture delivered and they have more score in exams.

3. Generally the more interested a student is about the lectures being delivered,the more front he/she is in classroom and thus this results in more grades.

Three possible cause-and-effect relationships explaining why students with good grades sit at the front include higher motivation, increased teacher attention, and the third-factor explanation such as self-confidence or socioeconomic status, which could indicate a spurious relationship.

You observe that classmates who get good grades tend to sit toward the front of the classroom, while those who receive poor grades tend to sit toward the back. Three possible cause-and-effect relationships for this nonexperimental observation could include:

It is difficult to determine without further investigation whether the observed correlation indicates a causal relationship or a spurious relationship. Investigating the root causes of this observation would require a more rigorous research design with clear independent and dependent variables, as well as controls to account for potential confounding factors.

Answer:

% here x and y is given which we can take as

x = 2:2:10;

y = 2:2:10;

% creating a matrix of the points

point_matrix = [x;y];

%  center point of rotation  which is 2,2 here

x_center_pt = x(2);

y_center_pt = y(2);

% creating a matrix of the center point

center_matrix = repmat([x_center_pt; y_center_pt], 1, length(x));

% rotation matrix with rotation degree which is 45 degree

rot_degree = pi/4;      

Rotate_matrix = [cos(rot_degree) -sin(rot_degree); sin(rot_degree) cos(rot_degree)];

% shifting points  for the center of rotation to be at the origin

new_matrix = point_matrix - center_matrix;  

% appling rotation  

new_matrix1 = Rotate_matrix*new_matrix;          

Explanation:

We start the program by taking vector of the point given to us and create a matrix by adding a scaler to each units with repmat at te center point which is (2,2). Then we find the rotation matrix by taking the roatational degree which is 45 given to us. After that we shift the points to the origin and then apply rotation ans store it in a new matrix called new_matrix1.

Answer:

#include<iostream>

using namespace std;

int main(){

   //initialization

  int arr1[10] = {2,4,6,1,7,9,0,3,5,8};

  int temp;

   int size_arr;

   //nested for loop

  for(int i=0;i<size_arr-1;i++){

   for(int j=0;j<size_arr-i-1;j++){

       if(arr1[j]>arr1[j+1]){ //compare

               //swapping

           temp = arr1[j];

           arr1[j]=arr1[j+1];

           arr1[j+1]=temp;

       }

   }

  }

  //display the each element

  for(int i=0;i<10;i++){

   cout<<arr1[i]<<" ";

  }

    return 0;

}

Explanation:

Create the main function and declare the variable and defining the array with 10 values.

take the nested for loop, nested loop means loop inside another loop.

the outer loop traverse in the array from 0 to size-1.

and inside loop traverse from 0 to size -i-1, because for every cycle of the outer loop the one element is sorted at the end. so, we do not consider the element from the last for every cycle of the outer loop. That's why (size-i-1)

In the bubble sort, the first element compares with the second element and if the first id greater than the second then swap the value. so, for the above algorithm, we take the if statement and it checks the condition if the condition becomes true then the swap algorithm executes.

we take a third variable for swapping. after that, if the outer loop condition false it means all elements will traverse and then the loop will terminate.

and finally, take another for loop and display the output.

Final answer:

The answer provides a Python program example that uses the bubble sort algorithm to sort an array of 10 integers. The program defines a function, bubble_sort, which sorts the array in ascending order and then prints the sorted array.

Explanation:

To sort an array of 10 integers using the bubble sort algorithm, you can use the following program as a reference. Bubble sort compares adjacent elements and swaps them if they are in the wrong order. Here's a basic example in Python:

def bubble_sort(arr):
   n = len(arr)
   for i in range(n):
       swapped = False
       for j in range(0, n-i-1):
           if arr[j] > arr[j+1]:
               arr[j], arr[j+1] = arr[j+1], arr[j]
               swapped = True
       if not swapped:
           break
   return arr

# Example array:
numbers = [64, 34, 25, 12, 22, 11, 90, 88, 66, 23]
sorted_numbers = bubble_sort(numbers)
print("Sorted array is:", sorted_numbers)

This program will sort the given array of integers in ascending order. The function bubble_sort takes an array as input, performs the bubble sort algorithm, and returns the sorted array.

Explanation:

The peek method retrieves the element at the top of a stack without deleting/removing it, the only exception that can occur is when the stack used is empty. It would look as follows when you use the method >> STACK.peek().

Answer:

The answer to this question is A. 0.

Explanation:

In this segment of code #define MAX 50 is used.It is a pre-processor directive and in pre processor directive it is a MACRO means whenever the compiler encounters the word MAX in the execution it replaces MAX with 50.

So the size of the array becomes 50 and the indexing starts from 0 and upto 49.
