Some misconceptionsabout communication are:

o Communication solves all problems.

o Communication physically breaks down.

o The meaning we attach to a word will be themeaning everyone else attaches to

the word.

o All of the given options

Answer:

A

Explanation:

B is a print statement.

C is a function invocation

D is a function declaration

A prototype is actually quite close to a declaration. The semi-colon at the end shows that no implementation will follow. Adding parameter names is allowed but would only be helpful for better understanding.

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.

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!

Answer:

Table buffers are tools used to avoid the process of accessing a database in servers.

A variable that holds an address is known as a pointer variable.

Such variable "points" to location of memory in computer, the location can be another variable, primitive data type, object and more.

The answer is therefore B.

Hope this helps.

A tuple is a sequence of grouped values. It serves to group, as if they were a single value, several values that, by their nature, must go together. The tuple type is immutable. A tuple cannot be modified once it has been created.

One of the reasons why there are tuples in phyton is that they are generally used to determinate that their content is not modified. They constitute a type of data widely used in the definition and call of functions and in other situations where it is necessary to use the capacity of tuples to be packaged and unpacked. The benefits of immutability are simplicity, reduced demand for storage space and high performance in processing, issues that exceed the lists.

Another reason why there are tuples on python is that tuples are faster than lists. If a constant set of values is defined and all that is going to be done is to iterate over them, it is better to use a tuple instead of a list.

Tuples in Python are immutable, which ensures data integrity and can be used as keys in dictionaries. They contribute to clearer, more maintainable code by supporting tuple assignment where multiple variables can be assigned in a single statement.

Reasons Why Tuples Exist in Python

One of the reasons why tuples exist in Python is because they are immutable. This means once a tuple is created, it cannot be modified, which is an essential feature in situations where a constant set of values is needed, and it prevents the data from being altered accidentally. Another reason for the existence of tuples is their ability to be used as keys in dictionaries due to their immutability and hashability. This allows for the sorting of lists of tuples and using them in data structures where the integrity of the key must be preserved.

Besides, tuples can increase code clarity and integrity in contexts where an immutable sequence of elements is expected. An example is passing arguments to a function; tuples can reduce the risk of bugs associated with mutable objects, hence reducing the potential for unexpected behavior due to aliasing.

Moreover, tuples can streamline tuple assignment in Python, where multiple variables can be assigned values simultaneously on the left side of an assignment statement. This can lead to cleaner, more readable code.

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.

Explanation:

if ..else is the conditional statement which is used to check the condition is true or not, if the condition is true that execute the particular statement and if not it moves to else part for execution.

if condition is more than two we can use continuous if else statement

Syntax:

if(condition)

{

 statement;

}else if(condition)

{

  statement;

}else

{

 statement;

}

In the code:

The value of the input is 5.

first it goes to if part and check condition if 5 > 5, condition false it equal to 5 not greater than 5.

it then moves to else if part and check condition if 5 > 2, condition is true,

it execute the code inside the else if part. so, input_value become

5+10 which 15.

after that, program control terminate the if else statement it does not check further.

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.

These are the steps in JSP life cycle.

1. Conversion JSP page to Servlet .

2.Compilation of JSP page(test.java)

3.Class is loaded (test.java to test.class)

4.Instantiation (Object is created)

5.Initialization (jspInit() method is only called once at the time of servlet     generation )

6.Request processing(_jspService() method is used for serving requests by JSP)

7.JSP Cleanup (jspDestroy() method is used for removing JSP from use)

There is no *jspService() method in the JSP life cycle.

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.    

Answer:

All of Given

Explanation:

The throw keywords can be used to throw any Throwable object. The syntax is :

throw <Throwable instance>

Note that Error and Exception are subclasses of Throwable while RuntimeException is a subclass of Exception. So the hierarchy is as follows:

Throwable

-- Error

-- Exception

   -- RuntimeException

And all of these are valid throwable entities. As a result "All of Given" is the most appropriate option for this question.

Answer:

The answer is B: throwable

Explanation:

Throwable is the super class of all exceptions

Answer:

The given statement is True

Explanation:

Since, a bit pattern is a bit sequence, basically, data which as such has no intrinsic meaning.

Bit pattern is  a bit sequence or sequentially arranged binary digits.

It is used to describe bit sequence in communication channels, memory or some other device.

Bit patterns are used to represent instructions, floating point numbers,  signed/unsigned integers.

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.

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

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.  

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.

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.

Answer:

False

Explanation:

The term asymptotic means approaching a value or curve arbitrarily closely

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.

Answer: Single  precision

Explanation:

A 1-bit sign, 8-bit exponent, 23-bit fraction and a bias of 127 is used for the single precision binary floating point representation. As, single precision is the smallest change that can be represented as floating point representation is called as precision. It is the computer format number, which occupies 32 bits in the computer memory.

The IEEE standard specify a binary 32 as:

Sign bit- 1 bit

Exponent width- 8 bits

Significant and precision- 24 bits (23 stored as explicitly)

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.

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.

Answer:

#include <iostream>

using namespace std;

int main()

{

   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.

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;
