When mathematicians use a two-dimensional array, they often call it a ____.

a.
matrix

b.
grid

c.
net

d.
mesh

Answers

Answer 1

Answer:

matrix

Explanation:

The two dimensional array store the value similar to matrix.

Two dimensional array contain row and column similar to matrix.

For example:

int arr[3][3], it means 3 rows and 3 column

and [tex][A]_{3*3}=\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]

and if we want to retrieve the data from array arr[1][2], it means first row and second column.

so, 2 dimensional array is basically a matrix.

In the MOV instruction both operands i.e. source andthe destination cannot be

_______________ operands.

Answers

Answer:

an immediate.

Explanation:

It is because of the instruction encoding and decoding.Intel which make these instructions decided not include instructions which provide no real advantage. MOV segment register is one of them because segment register need not to be changed very often.This saves the space in instruction encoding.

Answer: In the MOV instruction both operands i.e., source and the destination cannot be immediate operands.

Explanation:

The destination operand must be in data alterable mode and it cannot be an an immediate operand, or a segment register. Basically, the mov operation are used to copy the values stored in one registers to another registers. It can be used to load a small integer in the register.

This is a form of load balancing where larger workloads are issued to IT resources with higher processing capacities

a. Pay-Per-Use Monitor

b. Asymmetric Distribution

c. SLA Monitor

d. Workload Prioritization

Answers

Answer:

The correct answer is b. Asymmetric Distribution.

Explanation:

Asymmetric Distribution has to do with those larger workloads which are issued to IT resources with higher processing capacities. The Pay-Per-Use Monitor is where the billing system relies on. The Workload Prioritization is where workloads are prioritized according to their level. And the SLA monitor is a contract between a service provider and the customer. So, the most correct answer is b.Asymmetric Distribution.

Answers

Answer:

The final value of i will be 5 at the end of the program.

i=0, i≤4, prints 0.

i=1, i≤4, prints 1.

i=2, i≤4, prints 2.

i=3, i≤4, prints 3.

i=4, i ≤ 4, prints 4.

i=5, i is not ≤ 4, stops here.

Q-5:

pow(2,3) = 8 and pow(3,2)=9, so they are not same.

Q-6:

The functions pow(), sqrt(), and fabs() are found in which cmath

Explanation:

Final answer:

The final value of i is 5. pow(2,3) is not the same as pow(3,2). The functions pow(), sqrt(), and fabs() are located in the cmath include file.

Explanation:

Final Value of Variable i

The final value of i at the end of the loop in the C++ code is 5. This occurs because the loop continues to increment i until the condition i <= 4 is no longer true. After the last execution with i equal to 4, the loop increments i to 5 and then checks the condition, which fails, thus exiting the loop and leaving i with a value of 5.

Power Function Comparison

pow(2,3) is not the same as pow(3,2). The pow function returns the value of one number raised to the power of another. Thus, pow(2,3) calculates 2 to the power of 3 (2*2*2), which equals 8, while pow(3,2) calculates 3 to the power of 2 (3*3), which equals 9.

Function Include Files

The functions pow(), sqrt(), and fabs() are all found in the cmath include file of C++.

In a doubly linked list, every nodecontains the address of the next node and the previousnode except for the ____ node.
a. middle

b. last

c. first

d. second to last

Answers

Answer:The answer is (c).first.

Explanation:

In doubly linked list each node possesses the address of next node(except last node) because there is no node present after the last node .

and the address of previous node(except first node) because there is no node present before the first node.

So the conclusion is that the first node does not contain the address of previous node and the last node does not contain the address of the next node.

Digits Sum Write a function main( that reads a positive integer, calls the function digits which finds the digits sum of that integer. The function main( prints the sum. Sample input/output: Enter a positive integer: 20010 The digits sum of 20019 is 3

Answers

Answer:

#include<iostream>

using namespace std;

int digits(int number){

   int sum=0;

   while(number != 0){

       int rem = number % 10;

       sum = sum + rem;

       number = number/10;

   }

   return sum;

}

int main(){

   int number;

   cout<<"Enter the integer: ";

   cin>>number;

   int result = digits(number);

   cout<<"The sum of digits is: "<<result<<endl;

}

Explanation:

Include the library iostream for use of input/output.

Then, create the function digits with return type int.

Take a while loop and put a condition number not equal to zero.

the while loop executes the until the condition is not false.

In the while loop, take the remainder of the number and store in the rem variable.

after that, the store in the sum then reduces the number by dividing 10.

for example:

the number is 123.

rem = 123%10 it gives the value 3.

sum = 0+3=3

number = 123/10 it equal to 12

then,

rem = 12%10 it gives the value 2.

sum = 3+2=5

number = 12/10 is equal to 1

the same process executes until the number becomes zero and then the while loop terminates and the sum value returns to the main function.

create the main function and take the value from the user and call the function with the argument number.

and finally, print the result.

Write a programe to add two numbers using function with return type"void".

Answers

Answer:

//create the function which add two number

void addTwoNumber(int num_1,int num_2)

{

   int result = num_1 + num_2;  //adding

   

   cout<<"The output is:"<<result<<endl;  //display on the screen

}

//main function

int main(){

   //calling the function

   addTwoNumber(3,6);

   return 0;

}

Explanation:

First, include the library iostream for using the input/output instructions.

then, create the function which adds two numbers. Its return type is void, it means the function return nothing and the function takes two integer parameters.

then, use the addition operation '+' in the programming to add the numbers and store the result in the variable and display the result.

create the main function for testing the function.

call the function with two arguments 3 and 6.

then, the program copies the argument value into the define function parameters and then the program start executing the function.

Answers

Answer:

1. ‘cout’ was not declared in this scope.

2. ‘cin’ was not declared in this scope.

3. lvalue required as left operand of assignment.

Explanation:

The code gives the error cout and cin was not declare. This error means, we not include the library where they define.

cout and cin is the input/output instruction and they include in the library iostream file.

the last error is lvalue required as left operand of assignment.

lvalue means the assignable value, we actually do the wrong assignment.

number1 + number2 = sum;

here, sum is is the assignment variable. so, it must be in the right side of the '=' operator.

sum = number1 + number2 ;

Now, the above is correct. the value number1 plus number2 is assign to sum.

Give three reasons why you think ETL functions are mostchallenging in data warehouse environment.

Answers

Final answer:

ETL functions are challenging in a data warehouse environment due to the high volumes of data, the variety and inconsistency of data formats and structures, and the imperative need to maintain data quality.

Explanation:

ETL, which stands for Extract, Transform, Load, is a critical process in a data warehouse environment. It involves the integration of data from multiple sources, transformation of that data into a format suitable for analysis, and then loading it into the data warehouse.

There are three main reasons why ETL functions can be particularly challenging in this setting:

Data Volume: The sheer amount of data that needs to be processed can be overwhelming. Handling large volumes of data requires robust systems and can be time-consuming, thus posing a significant challenge.

Data Variety: Different data sources can mean inconsistent formats, structures, and quality. Achieving consistency and accuracy in data transformation is a difficult task that demands meticulous attention to detail and sophisticated processes.

Data Quality: Ensuring the correctness, completeness, and reliability of data is paramount. This can be a daunting task due to potential errors in the data and the complexity of data validation rules.

The challenges of ETL highlight the importance of having a well-designed data warehouse architecture and a comprehensive approach to data management.
