Answer:
name(argument_1, argument_2, argument_3,.......);
Explanation:
The function is a block of the statement which performs the special task.
Syntax for calling the function:
name(argument_1, argument_2, argument_3,.......);
we write the name of the function and passed the arguments.
we can pass any number of arguments with separator ',' in the function calling.
for example:
1. print(name, value, count, a, b);
2. print(name, value);
Here, name, value, count,a and b are the arguments of the function.
if we does not pass any argument, the function still valid in the programming.
we can pass from Null to any number of argument.
Final answer:
To use multiple arguments in a method, separate them with a comma within the method's parentheses. This approach enables methods to perform more dynamic and flexible operations with variable inputs. An example includes a method to add two numbers, defined with two arguments, which are supplied in the same order when the method is called.
Explanation:
Using multiple arguments in a method allows for more dynamic and flexible code, enabling the method to perform tasks with variable inputs. In programming, a method can be understood as a set of instructions that performs a particular task. Arguments are inputs you give to a method so that it can perform its task with specific data. To use multiple arguments, you simply separate them with a comma within the parentheses of a method call.
For example, if you have a method designed to add two numbers, you might define it as follows: add(int num1, int num2). Here, num1 and num2 are the arguments. When calling this method, you would provide two numbers as arguments like add(5, 7), instructing the method to add 5 and 7.
In more complex scenarios, such as in object-oriented programming, methods might require multiple arguments of different types, such as strings, integers, or even objects. This variety allows developers to construct highly customizable and efficient code. For instance, a method for creating a user profile might require several arguments such as name, age, and email address: createUserProfile(String name, int age, String email).
When designing methods that accept multiple arguments, it’s important to consider the order of arguments, as they must be supplied in the same order when the method is called. Additionally, leveraging method overloading - defining multiple methods with the same name but different parameters - increases flexibility and readability in how methods can be used with varying arguments.
Do you think that people accept poor quality in information technology projects and products in exchange for faster innovation? What other reasons might there be for such poor quality?
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.
Who seeks price does not find quality?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.

.All of the following are true with the respect to implicitinvocation except:
A.it is based on the notion of bradcasting B.it is event-driven C.data exchange usesrepository D.components are instances ofabstractions
Answer: D) components are instances of abstraction
Explanation:
As, implicit invocation is the process by which it is used by the the software designer for styling the architecture of the software,where the event handling structured are formed in the system. The main aim of the implicit invocation is to separated the conceptual concern for maintaining or improving the ability of the software engineer. It is basically based on the notion of the broadcasting and based on the event driven. The components are the instance of the abstraction which are not used as the components in implicit invocation which are relinquished control the system over the computational performance,this is the major disadvantage of the implicit invocation.
Do the following SQL questions. The resulting columns must all have descriptive names. You must show the result of the query. For example, if the query is:
Show the office id, the city, and the region
Your query should be:
select office, city, region
Answer:
We can use CREATE command to create tables with columns having descriptive names
Explanation:
Firstly, create a table using CREATE command in SQL. The syntax is as follows:
CREATE TABLE [table_name]
(
[col_name] [datatype]),
[col_name] [datatype]),
[col_name] [datatype]),
[col_name] [datatype])
)
Once the table is created, we can insert the data into table using INSERT command. It's syntax is as follows:
INSERT INTO table_name VALUES('', '', '')
if datatype is string, values must be entered within single quotes. If datatype is int, values are entered directly without using quotes.
Now, you can select the data from the table using SELECT command. It's syntax is as follows:
SELECT column-list FROM table_name
If you want to filter rows according to conditions, you can use WHERE command.
I have created sample table and inserted some data into it. Now, I applied some queries on it to select data from the table.
I have written in a text file and attached the same. Please find. Thank you!
When an expression containing a ____ is part of an if statement, the assignment is illegal.
a.
greater than sign
b.
double equal sign
c.
single equal sign
d.
Boolean value
Answer:
single equal sign
Explanation:
The if statement is used for check the condition.
syntax:
if(condition)
{
statement;
}
let discuss the option one by one for find the answer:
Option a: greater than sign
this assignment operator '>' is valid. it is used to create the condition like n>0, p>4.
Option b: double equal sign
this assignment operator '==' is valid. it is used to check the equal condition.
like 2 == 2.
Option c: single equal sign
this assignment operator '=' is not valid. it is used for assign the value to variable not for checking like a=2, in this 2 assign to a but it not apply the condition.
Option d: Boolean value
we can provide the Boolean value as well if Boolean is TRUE, if condition true otherwise false.
Therefore, the option c is correct option.

Create an application program that will compute theradius and circumference of a circle. Write a Main class withHelper methods to prompt for and input the radius of acircle(getRadius), calculate thecircumference(calcCirc), and calculate thearea(calcArea) of a circle. Define the radius,area, and circumference in main which will call each calc method,passing radius to each one. Assume PI = 3.14159 or use theMath.PI builtin constant. Format theoutput to show two decimal places in the calculatedvalues.
Final answer:
An application to compute the radius and circumference of a circle requires creating a Main class with methods to input radius, calculate circumference, and area, formatting results to two decimal places using Math.PI.
Explanation:
To create an application that calculates the radius and circumference of a circle, you will need to define methods within your Main class. The getRadius method will prompt the user for input, calcCirc for calculating the circumference using the formula C = 2 * PI * r, and calcArea for calculating the area with A = PI * r * r. You should use the Math.PI constant for PI, and ensure all results are formatted to two decimal places.
Sample code structure in Java:
public class Main {
public static void main(String[] args) {
double radius = getRadius(); // prompts user and gets radius
double circumference = calcCirc(radius);
double area = calcArea(radius);
System.out.printf("Radius: %.2f\n", radius);
System.out.printf("Circumference: %.2f\n", circumference);
System.out.printf("Area: %.2f\n", area);
}
// Helper methods here
}
Ensure that you correctly use double data types for storing the input from the user, as well as the calculated values, since these can include decimal points.
Some data files should be totally hidden from view, while others should have ____ so users can view, but not change, the data.
Answer
no-access properties
read-only properties
full-access properties
write-only properties
Answer:
read-only properties.
Explanation:
Only the read only properties can view but cannot change the data.The user don't have access to the no access properties, full-access properties can read and modify the data.The write only properties can only modify the data.So to only view the data the data should have read only properties.
Random access iterators are ____ iterators that can randomly process elements of a container.
A.
input
B.
forward
C.
bidirectional
Answer:
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.
The main benefit of shielded twisted pair cabling over unshielded twisted pair is that STP is much more durable.
a) True b) False
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.
Examine the following code and answer questions 7 below. IGNORE COMPILE ERRORS.
int j = 0;
for (j = 0; j <= 9; j++)
{ printf( “%d”, 1 + ( rand() % 5 )); }
7. What are the POSSIBLE range of numbers that will be printed by the “printf()” statement above?
Answer:
1 to 5 both included.
Explanation:
rand() is the function which is used to generate the random values within the range.
for example:
rand() % 10;
it means it generate the output from 0 to 9. if we add the 1 in the above code:
like 1 + (rand() % 10);
Then, the range is from 1 to 10, it increase the range from start and end as well.
in the question code, for loop is used to for executing statement 9 times.
rand() % 5
it generate the number from 0 to 4.
and 1 + ( rand() % 5 ))
it generate the output from 1 to 5
Therefore, the answer is 1 to 5.
Examine the following code. What will be the output from the “printf()” statement below?
#define S_SIZE 10
char s[10] = { ‘g’ , ’o’ , ’m’ , ’i’ , ’z’ , ’z’ , ’o’ , ’u’ };
int j = 0;
for (j = S_SIZE -2; j > 4; j--) { printf( “%c”, s[j]); }
Using the definitions below (IGNORE ALL COMPILE ERRORS):
char s1 [ 50 ] = “JACK”, s2 [ 50 ]=”FRED”;
Answer:
uoz (with one space on the left most side)
Explanation:
#define is used to define macros, it just substitutes the value in the program.
For example:
#define S_SIZE 10
so, it put the value 10 where we write 'S_SIZE'.
then, character array define which has 8 elements.
Note: Array index starts from 0.
the, for loop is execute from 8 to j > 4( means 5).
it prints s[8] which not present in the array so, it prints blank space.
s[7] it prints 'u'
s[6] it prints 'o'
s[5] it prints 'z'
then the loop will be terminated.
Therefore, the answer is uoz with space on the leftmost side.

A program written in ____ is the most basic circuitry-level language.
a.
Java
b.
machine language
c.
BASIC
d.
C
Answer:
The correct answer is B. Machine Language.
Explanation:
A programming language is a language that can be used to control the behavior of a machine. It consists of a set of syntactic and semantic rules that define its structure and the meaning of its elements, respectively.
A low level language is one that exposes the programmer to the operations of the machine, without contributing its own constructions. That is, in low level languages it will be possible to do everything the computer is capable of doing, but to achieve this the programmer will have to be intimately familiar with the details of the electronics in which his program runs.
An example of the low level language is the machine language that consists of binary instructions ready to run. The machine language is the one that gives orders to the machine, which are the fundamental operations for its operation. The computer only understands a language known as binary code or machine code, consisting of zeros and ones, which are easy to understand by the hardware of the machine. This language is much faster than high level languages. The disadvantage is that they are quite difficult to handle and use, besides having huge sources codes where finding a fault is almost impossible.
Final answer:
Machine language is the most basic circuitry-level language, written in binary code. High-level programming languages like C provide a more user-friendly alternative for programming.
Explanation:
The program written in machine language is the most basic circuitry-level language. Machine language is directly executed by the central processing unit (CPU) and is composed of binary code, which consists of zeros and ones. This type of programming is considered a low-level language, as opposed to high-level programming languages like Java, BASIC, or C, which require a compiler to convert their instructions into machine code that the CPU can understand and execute.
What are table buffers?
Answer:
Table buffers are tools used to avoid the process of accessing a database in servers.
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. What are three possible cause-and-effect relationships for this nonexperimental observation?
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.
Explanation: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:
Students with higher motivation levels might choose to sit at the front to minimize distractions and engage more directly with the lesson, leading to better performance.Teachers may pay more attention to students at the front, which might result in better understanding and higher grades for these students due to increased interaction.There could be a spurious relationship where both seat choice and academic performance are influenced by a third factor, such as self-confidence or socioeconomic status, as shown in Rist's study which linked social class with proximity to the teacher.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.
What is DATE data type and its syntax and what is TIMESTAMP data type and its syntax in SQL language.Explain the difference between both of them .
Answer: The DATE datatype give us the particular date whereas TIMESTAMP gives us the date as well as the time as the particular moment.
Explanation:
DATE datatype gives us the date in the format yyyy-mm-dd. The timestamp format is yyyy-mm-dd hh:mm:ss. time stamp are of two types :
timestamp with time zone and timestamp without time zone.
Date is the date on that particular day whereas the timestamp is the date along with the specific time when the query is executed.

When multiple exceptions are caught in the same try statement and some of them are related through inheritance, does the order in which they are listed matter?
Answer:
Yes, the order in which the catch blocks are listed matter in case where multiple exceptions are caught in the same try statement and some of them are related through inheritance.
Explanation:
A try block may be followed by one or mutiple catch blocks. Each catch block should contain a separate exception handler. Thus, if we need to perform different tasks for the occurrence of different exceptions then we need to use java multiple catch blocks.
Every catch block should be ordered from the most particular to the most generic like catch for the NumberFormatException class must come before the catch for the Exception class.
Thus, the order in which the catch blocks are listed matter in case where multiple exceptions are caught in the same try statement and some of them are related through inheritance.
the largest distribution of software cost will be when in the programs life cycle?
Answer: Early
Explanation:
The largest distribution of software cost will be in the early stages of program life cycle. The different phases in the program life cycle are edit time, compile time, link time, distribution time, installation time, load time, and run time. So during early program life cycle we have editing stage which involves correcting the code , debugging earlier codes and addition of features into the code which leads to a large software cost

{
float celsius;
cout<<"Enter the temperature in Celsius: ";
cin>>celsius;
float Fahrenheit = 1.8 * celsius + 32;
cout<<"The temperature in Fahrenheit is: "<<Fahrenheit<<endl;
}
Explanation:
first include the library iostream in the c++ programming.
Then, create the main function and declare the variable celsius.
cout is used to print the message on the screen.
cin is used to store the user enter value in the variable.
then, apply the formula for calculating the temperature in Fahrenheit
and store the result in the variable.
Finally, print the result.
What is variable hoisting in JavaScript? Provide examples.
Answer:
before executing a code using javascript hoisting we can move any variable declaration to the top of the scope in a code.
Explanation:
It is to be remembered that hoisting works with declaration not with initialization.
example:
//initializing a variable s
var s = 2;
t = 4
elem.innerHTML = s + " " + t; // Display s and t values
// initializing a variable for hoisting
var t;
____ refers to the order in which values are used with operators.
a.
Floating
b.
Associativity
c.
Declaration
d.
Initialization
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.
Given the following code. float dollars[5] = {1986.10, 240.99, 215.50, 75.00, float euros[5]; Give the C++ code that will fill the euros array with the corresponding euro value dollars array. So the first element of euros will be equivalent to the euro vat clement of the dollars array, etc. Use the following formula: 1 dollar = .92 euro
Answer:
#include <iostream>
using namespace std;
int main()
{
float dollars[5] = {1986.10, 240.99, 215.50, 75.00, 65.97};
float euros[5];
for(int i=0;i<5;i++){
euros[i] = dollars[i]*0.92;
}
for(int i=0;i<5;i++){
cout<<euros[i]<<endl;
}
return 0;
}
Explanation:
First include the library iostream for input/output.
then, create the main function and declare the arrays.
after that, take a for loop for traversing through dollars array and convert into euros by multiply each element with 0.92 value and store in the euros array with same index value as dollars array.
finally, take the for loop for print each element of the euros array.
