?? arr.length

?? arr.length – 1

?? arr.size – 1

?? arr.length()

Answers

Answer 1

Answer:

The answer is option 1 arr.length.

Explanation:

In java arr.length gives the correct number of elements in the array.The length is function is only applicable for arrays.

The length() method is applicable for strings.

arr.length-1 will give 1 element less.

There is no .size for arrays in java.

So we conclude that arr.length is correct way of getting the number of elements in one dimensional array arr.

Implement RandMultipByVal function, which gets one integervariable as its argument
and multiply it by a random number between 1 to10 (use call-by-value approach).

Answers

Answer:

#include <iostream>

#include <stdlib.h>

#include <time.h>

using namespace std;

void RandMultipByVal(int number){

   srand(time(NULL));

   int random = rand()%10+1;

   cout<<random*number;

}

int main()

{

 

  RandMultipByVal(4);

  return 0;

}

Explanation:

Include the three libraries, iostream for input/output, stdlib.h for rand() function and time.h for srand() function.

Create the function with one integer parameter.

Then, use srand() function. It is used to seed the rand() function or locate the starting point different in different time.

rand(): it is used to generate the random number between the range.

for example:

rand()%10  it gives the random number from 0 to 9.

if we add 1, then it gives from 1 to 10.

After that, multiply with parameter value and then print the result.

For calling the function create the main function and call the function with pass by value.

Solve the following system of algebraic equations: Y = 1-x^2 and y = 1+x

Answers

Answer:

x=0;   x=1

Explanation:

The system presents a quadratic equation and a linear equation. Therefore, the result will have two solutions.

The first step is to match the two equations:

[tex]1+x=1-x^{2}[/tex]

Then we clear the equation by zeroing.

[tex]0=x^{2} +x+1-1[/tex]

Now we perform indicated operations

[tex]x^{2} +x=0[/tex]

We factor with the common factor method

x(x+1)=0

We equal each factor to zero and get the results

x=0

(x+1)=0

x=-1

The two values ​​that satisfy both equations are 0 and -1

What is the output of the following program segment?

int x = 0;

++x;

x++;

++x;

x++;

++x;

Answers

Answer:

5

Explanation:

The operator 'x++' is called the post increment operator, it is assign first and then increment.

The operator '++x' is called the pre increment operator, it is increment first  and then increment.

So, both are increment operator which increment the value by one.

initially the value of x is zero,

++x increase the value to 1 and than assign to x.

then, x++ it assign to x first then increment by 1 means x=2

and so on.....

Their are five increment operator are used. so, the result is 5.

. Two or more functions may have the same name, as long as their _________ are different.

Answers

Answer:

Number of parameters.

Explanation:

The function is a block of the statement which performs the special task.

Syntax:

type name(parameter_1,parameter_2,...){

statement

}

we can define any number of function in the code and also with the name as well.

But when we define the function with same name the number of parameter define in both function must be different.

for example:

1. int print(int a){

statement;

}

2. int print(int a, int b){

statement;

}

first has one parameter and second has two parameters.

Both are valid in the code.

Answers

Answer:

None

Explanation:

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

Unfortunately, none of these answers would be factually nor grammatically correct. For Starters Kona is not an island Kailua-kona is the capital town of the Big Island in Hawaii.

Regardless of that fact, none of the answers given would make the sentence make sense grammatically. The Only way for the sentence to make sense grammatically, the answer either needs to stay blank or be Kailua. Like so...

Unlike the climate of the other islands of Hawaii, Kailua Kona contains 54 different temperate zones.

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

The sentence should be completed with 'that of,' making it read 'Unlike the climate of the other islands of Hawaii, that of Kona contains 54 different temperate zones.' Hawaii's diverse climates are heavily influenced by altitudinal variations and topographical features, leading to a range of climatic zones across its islands.

The correct completion for the sentence provided is that of. Hence, the complete sentence reads: Unlike the climate of the other islands of Hawaii, that of Kona contains 54 different temperate zones.

Hawaii is known for its diverse climate conditions. While most islands in the Pacific have a tropical type A climate, Hawaii has a variety of climatic zones due to its topography and altitudinal variation. For instance, Kauai, one of the Hawaiian Islands, is one of the wettest places on Earth, receiving more than 460 inches of rain per year. This high level of precipitation is due to the rain shadow effect caused by Mt. Wai'ale'ale. The windward side of this mountain receives substantial rainfall while the leeward side remains semi-desert due to the rain shadow.

Japan, another island group, also presents diverse climates. One of its islands, Hokkaido, features a type D climate and is known for snowfall that supports activities like downhill skiing. Japan's diverse climate is a result of its mountainous terrain, with active volcanoes like Mount Fuji influencing the regional climate conditions.

Answers

Answer:

A construct of systems, personnel, applications, protocols, technologies, and policies that work together to provide a certain level of protection

Explanation:

Creation of dynamic Trust Domains can be realized through collaborative, secure sharing solutions. The local system is able to trust a domain to authenticate users. If an application or a user is authenticated by a trusted domain, all domains accept the authenticating domain. For instance, if a system trust domain X, it will also trust all domains that domain X trusts. It is a two-way trust relationship and is transitive.

Answer:

A construct of systems, personnel, applications, protocols, technologies and policies that work together to provide a certain level of protection

Explanation:

A trust domain is a certificate that entities or users gain and is granted by a trusted domain this is that when you enter another software or other systems you will be recognized as a trusted character or user and gives protection between systems and softwares and provides protection for the users.

The factorial of a number n, written in math as n!, is the product of all the numbers from 1 to n or 1*2*3* … *n. Write a C++ program that requests a number from the user and then displays the factorial of that number. The program should only accept positive integers greater than 0.

Answers

Answer:

#include <iostream>

using namespace std;

int main()

{

   int factorial=1;

   int num;    

   

   cout<<"Enter any Number: ";    

   cin>>num;  

   

   for(int i=1;i<=num;i++){    

     factorial=factorial * i;    

   }    

   

   cout<<"The factorial of the number is "<<factorial<<endl;  

 

  return 0;

}

Explanation:

Create the main function and declare the variable.

then, print the message by using the cout instruction.

store the value enter by user in the variable.

After that, take a for loop from 1 to user value both are included.

and multiply the value with previous value and it happen until the condition in the loop true.

for example:

i=1

fact = 1*1=1

i=2

fact =  1*2=2

i=3

fact= 2*3=6  and so on....

finally print the result.

Final answer:

A C++ program to calculate the factorial of a positive integer uses a loop to successively multiply the numbers from 1 up to the input number. The program checks that the user input is a positive integer since the factorial is only defined for non-negative integers.

Explanation:C++ Program to Calculate Factorial

To calculate the factorial of a number in C++, we can ask the user to input a positive integer and then calculate the factorial by multiplying all the integers from 1 up to the number provided. The factorial of a number n, written as n!, is the product of all positive integers less than or equal to n. Below is a simple C++ program that calculates the factorial:

#include
using namespace std;

int main() {
  unsigned int number;
  unsigned long long factorial = 1;

  cout << "Enter a positive integer: ";
  cin >> number;

  if (number < 0) {
      cout << "Factorial of a negative number doesn't exist.";
  } else {
      for(int i = 1; i <= number; ++i) {
          factorial *= i;
      }
      cout << number << "! = " << factorial << endl;
  }
  return 0;
}

The program uses a loop to repeatedly multiply the factorial variable by each number up to the input number. We use an unsigned long long for the factorial variable to handle potentially large numbers, although there is still a limit to how large a number this data type can store. The program also includes a basic check to ensure that a negative number is not input, as factorials are only defined for non-negative integers.

Write a program that will compare two names. The program prompts the user to enter two names for a comparison. If the names are same, the program states that. If the names are different, the program converts both names to UPPERCASE, and compares then again. If they are equal, the programs displays a message stating that names are equal if CASE is ignored. Otherwise, the program prints names with a message that names are not equal.

Answers

Answer:

We can use comparison operator 'Equals to' (==) to compare two strings.

Explanation:

We can use conditional statement 'if else' to put conditions. If statement contains boolean expression.If statement is followed by else block. If the boolean expression evaluates to true, then the if block of code is executed, otherwise else block of code is executed.

If we want to compare two strings with uppercase, then we can convert the input strings given by users using ToUpper() string function.

For example,

 string abc;

string uppercase= abc.ToUpper(); // gives ABC as result

______ is the ability of a system to do more than one thing at a time. A. Multibusing c. online processing b. Multiprocessing d. Batch processing

Answers

Answer:

Multiprocessing.

Explanation:

In multiprocessing the system uses two or more processors to do more tasks simultaneously.

Final answer:

The ability of a system to do more than one thing at a time, known as multiprocessing, allows for the concurrent execution of multiple tasks by using multiple processing units or cores.

Explanation:

The ability of a system to do more than one thing at a time is known as multiprocessing. Multiprocessing systems have multiple processing units, commonly referred to as cores, which can execute tasks simultaneously. Unlike single-core systems, which can only handle one operation at a time, multiprocessing systems can perform multiple tasks concurrently, improving overall system efficiency and performance.

In the context of computers and operating systems, this capability allows a computer to run different processes at the same time, such as running a web browser while also running a spreadsheet application or virus scan. The operating system manages these processes and allocates processor time in such a way that users experience the tasks as though they are happening simultaneously.

By contrast, multibusing refers to a system where multiple buses allow many devices to connect and communicate with the CPU at the same time, while online processing is processing that is active and connected to a network. On the other hand, batch processing is a method of processing data in which transactions are collected and processed all at once at a particular time.
