What is the most popular service that was supported by almost every early computer networks? In your opinion, what’s the reason for that service to be most popular?

Answer:

#include<stdio.h>

int main()//driver function

{

int a=5;//initializing variable a

int b=7;//initializing variable b

int *p,*q;//declaring pointers p and q

p=&a;//assigning the address of a to p

q=&b;//assigning the address of b to q

printf("value of a is %d\n",a);

printf("value of b is %d\n",b);

printf("value of pointer p is %d\n",*p);

printf("value of pointer q is %d\n",*q);  

printf("address of a is %d\n",&a);

printf("address of b is %d\n",&b);

return 0;

}

Output

value of a is 5

value of b is 7

value of pointer p is 5

value of pointer q is 7

address of a is -783856608

address of b is -783856604

Answer: static

Explanation:

variables when declared static gets called statically meaning whenever a function call is made it get stored and it is not required to get the variable again when the function is again called. There scope is beyond the function block

Answer:

false

Answer:

d

Explanation:

In java you can use pareDouble(string str) to convert the string into double.

for example if you have string like this.

string str  = [tex]"16.45" ;[/tex]

then you can use

double mydouble = Double.parseDouble(str);

print(mydouble); //it will print out 16.45

but if the string would not be able to be parsed into double then you will get an error.

Answer:

Explanation:

We can divide array A into two arrays B , C

B would contain the sorted n elements.

C would contain the unsorted m elements.

Now we can sort C using merge sort with worst time complexity mlogm.

When you will have array C sorted you can concatenate with B and put it back in A.

Answer:

C. Fields

Explanation:

Fields are used to store all the data in a database.

Fields are used to store all the data in a database. The correct option is C.

A database is a collection of data that has been organized to make it simple to manage and update. Data records or files containing information, including as sales transactions, customer information, financial data, and product information, are often aggregated and stored in computer databases.

A database field is a collection of identical data values in a table. It is also known as an attribute or a column. Most databases also permit complicated data storage in fields, including images, whole files, and even movie clips. A lot does not necessarily have simple text values just because it supports the same data type.

Therefore, the correct option is C. Fields.

using namespace std;

//main function

int main(){

   //initialization

   long b1;

   int d1=0,count_pos=0;

//display the message

   cout<<"Enter the binary number: ";

   cin>>b1;  //store the value

   //loop for take the digit one by one

       count_pos++;

       b1 = b1/10;

   }

   //display the output

   cout<<"The decimal number is: "<<d1<<endl;

}

Explanation:

Create the main function and initialize the variables. Then, display the message on the screen by using the instruction cout and then, store the input enter by the user into the variable. Here, the variable declares with type 'long' because of the size of the input.

After that, we take a while loop for splitting the binary number into the digits and then we can do the operation.

Let's understand how you can convert binary to decimal with an example:

let the binary number is 1001:

decimal number is [tex][tex]1*2^{3}+0*2^{2}+0*2^{1}+1*2^{0}=9[/tex][/tex]

we put the same algorithms in the code. split the number into digit and then multiply with n raised to the power of 2 here, n is the position of digit from left to right.

NOTE: Position starts from zero.

and then, add the values. this process continues until the number is not zero.

After that, display the output on the screen.

 software quality dilemma is a situation where there is confusion regarding what should we prioritize : a good quality work or a fast paced work. In software development , many a times there will be deadlines to achieve, in such cases software quality dilemma is bound to occur. A developer would have to choose between writing and optimized and well commented code or just get the job done without proper optimized or reviews. In same lines, many companies have to decide between regular reviews and expert opinions of a product for good software quality or bypass them to meet budgets and deadlines.

In short, a software quality dilemma means a situation of production of software system that has terrible quality which causes low sales.

A software quality dilemma refers to a situation where there is a confusion regarding what should we prioritize whether a good quality work or a fast paced work with little quality,

Answer:

10.5

Explanation:

1010.1

Handy method you can find searching google images, and I originally learned

from some guy teaching an online java course.

.1 --> 1 * 2^(-1) = 0.5

0 --> 0 * 2^(0) = 0

1 --> 1 * 2^(1) = 2

0 --> 0 * 2^(2) = 0

1 --> 1 * 2^(3) = 8

0.5 + 2 + 8 = 10.5

If for some reason it isn't very clear, just take the number, (x) and multiply it

by two to the power of the position it is in. (e.g. first number before decimal point is 0, second 1, etc).

// c++ code to read the recieved calls

cout<< " Enter the calls recieved :";

cin>>callsRecieved;

cout<< " Enter operator on call : ";

cin>>operatorsOnCall;

// calculating the call per operator

calls_per_operator = callsRecieved/operatorsOnCall;

// printing the vaule.

cout<<" Calls recieved per operator are : " << calls_per_operator <<endl;

Final answer:

To find the number of calls received per operator, read inputs for callsReceived and operatorsOnCall, then divide callsReceived by operatorsOnCall using integer division and print the result.

Explanation:

To calculate the number of calls received per operator, you will first need to read values into the variables callsReceived and operatorsOnCall. You can do this using an input method appropriate for the programming language you're using (e.g., scanf in C, cin in C++, or input() in Python). Once you have these values, you perform the division of callsReceived by operatorsOnCall and print the result. Here is an example code snippet in Python:

Note that integer division with truncation is used (// in Python) to get an integer result.

DGL

Explanation:

SQL stands for structured query language which is used to interface with the database.

Let discuss the options:

1. DDL: This comes in the category of SQL and it stands for data definition language. This allows using CREATE, DELETE, DROP, ALTER, etc. of the table in the database.

2. DML: This comes in the category of SQL and it stands for data manipulation

language. This allows the user to use the INSERT, DELETE, UPDATE command which help to manipulate the data in the table.

3. DGL: This is not a part of SQL.

4. DCL: This comes in the category of SQL and it stands for data control language which allows the user to use ALTER PASSWORD, GRANT, REVOKE like command which helps the user to control access the data in the database.

Therefore, the correct answer is DGL.

Answer: serialize means to convert a java object to  byte stream and deserialize means to  convert the byte stream again to java object.

Explanation:

Both of these functions are present in  java.io library. we perform serviceable to java object in order to send it across the network where we can it can be stored in the hard disk because java object cannot be sent across the network to be stored in hard disks. Similarly deserialize enable to get the java object from the byte stream across  the network

Answer:

a-Effort is to be rewarded

Explanation:

When you ask for a raise in an organization,the one of the most important thing is Effort.There is a reason for everything in organization,if you are asking to raise your income organization will ask you on which basis you are asking.If you put extra hours than before or you gain some skill which is useful for the organization,so while asking for raise you should know the effort that you put in because effort is most important factor for a raise.

In formal organizations, Non cash benefits are not there so there is no purpose for asking it.

Employment does not matter for the peer in asking for a raise,sometimes it is used by small organizations but it is informal,the one should focus more on effort rather than the employment.

Emotional appeals may help in informal organization,never in formal organization.It only imprints negative image on peer's mind,if you want to have a raise you should focus on Effort.

Explanation:

Here the pointerVariableName can be used to access a classMemberName. This ca also be written as (*pointerVariableName).classMemberName.

Answer:

B. pointerVariableName->classMemberName

Explanation:

The syntax for accessing a class (struct) member using the operator -> is pointerVariableName->classMemberName.

Answer:

comma

Explanation:

The for loop is used to execute the specific statement again and again until the condition is false.

The syntax:

for(initialization;condition;increment/decrement)

{

  statement;

}

In the initialization, we an initialize more than one variable by using the 'comma' as separator.

similarly for condition and increment/decrement part as well.

for example:

for(int x = 0,y = 0;x<5,y<5;x++,y++)

{

  statement;

}

we can used as many as possible by using comma

Final answer:

A Java program can calculate an employee's net pay by deducting federal, state, Social Security, Medicare/Medicaid taxes, pension plan contributions, and health insurance costs from the gross pay. The net pay is then output as the amount the employee would receive in their paycheck.

Explanation:

To calculate the net pay for an employee after deductions, we need to write a Java program that considers the following deductions: Federal Income Tax at 15%, State Tax at 3.5%, Social Security Tax at 5.75%, Medicare/Medicaid Tax at 2.75%, a pension plan deduction at 5%, and a fixed amount for health insurance at $75.00.

Here is a simple example of how this Java program might look:

public class PaycheckCalculator {
   public static void main(String[] args) {
       double grossPay = 5000; // Example gross pay
       double federalTax = grossPay * 0.15;
       double stateTax = grossPay * 0.035;
       double socialSecurityTax = grossPay * 0.0575;
       double medicareTax = grossPay * 0.0275;
       double pensionPlan = grossPay * 0.05;
       double healthInsurance = 75;

       double netPay = grossPay - (federalTax + stateTax + socialSecurityTax + medicareTax + pensionPlan + healthInsurance);

       System.out.println("Net pay: $" + netPay);
   }
}

This program calculates each of the deductions based on the gross pay, subtracts them from the gross pay, and prints out the resulting net pay.

Answer:

False

Explanation:

Vector is a similar to dynamic array which has the ability to resize itself automatically.

empty() is a function used in the vector.

It is used to check the vector is empty or not.

it does not delete the element in vector, it just check the vector is empty or not, if vector empty it gives a Boolean value True other wise False.

Therefore, the answer is False.

Answer: after the required parameters.

Explanation:

Default arguments in a function should be defined after the required parameters because the required parameters are necessary but default arguments are not. If mixed parameters are allowed it will be very hard for the compiler to to judge which value matches which argument so there will be syntax error.

Answer: The c++ program to determine if the input number is prime is given below.

#include<iostream>

#include<math.h>

using namespace std;

int main() {

   int num, n;

   int prime=0;

   int i=3;

   cout<<"This program determines whether the number is prime." <<endl;

   do

   {

       cout<<"Enter any positive number."<<endl;

       cin>>num;

       if(num<=0)

           cout<<"Invalid input. Enter any positive number."<<endl;

   }while(num<=0);

   n=sqrt(num);

   if((num==1)||(num==2))

   {

       cout<<"The input "<<num<<" is prime."<<endl;

   }

   else if(num%2==0)

   {

       cout<<"The input "<<num<<" is not prime."<<endl;

   }

   else

   {

       do

       {

           if(num%i == 0)

               prime += 1;

           i++;

       }while(i<n);

        if(prime>1)

           cout<<"The input "<<num<<" is not prime."<<endl;

        else  

           cout<<"The input "<<num<<" is prime."<<endl;

   }

   return 0;

}

OUTPUT

This program determines whether the number is prime.

Enter any positive number.

-9

Invalid input. Enter any positive number.

Enter any positive number.

0

Invalid input. Enter any positive number.

Enter any positive number.

47

The input 47 is prime.

Explanation: This program accepts numbers beginning from 1. Any number less than 1 is considered as invalid input.

The test for prime is done using multiple if-else statements.

If number is even, it is not prime. Any number divisible by 2 is an even number. Except 2, it is even but also prime since it is divisible by itself only.

For odd numbers, number is divided by all odd numbers beginning from 3 till square root of the input. We first calculate and store square root of input.

n=sqrt(num);

An integer variable prime is initialized to 0. This variable is incremented each time the number is divisible by other number.

   int prime=0;

do

       {

           if(num%i == 0)

               prime += 1;            

           i++;

       }while(i<n);

Since prime number is only divisible by itself, all the prime numbers undergo this condition and hence, value of prime variable becomes 1.

The 0 and 1 values of variable prime indicate prime number. Other greater values indicate input is not prime.

if(prime>1)

           cout<<"The input "<<num<<" is not prime."<<endl;

        else  

           cout<<"The input "<<num<<" is prime."<<endl;

Python program checks if a positive integer is prime; uses a separate function to perform the primality test.

Here's a Python program that prompts the user to input a positive integer and then outputs a message indicating whether the number is a prime number:

```python

import math

def is_prime(n):

   if n <= 1:

       return False

   if n == 2:

       return True

   if n % 2 == 0:

       return False

   max_divisor = math.isqrt(n)

   for i in range(3, max_divisor + 1, 2):

       if n % i == 0:

           return False

   return True

def main():

   num = int(input("Enter a positive integer: "))

   if is_prime(num):

       print(f"{num} is a prime number.")

   else:

       print(f"{num} is not a prime number.")

if __name__ == "__main__":

   main()

```

Explanation:

1. The `is_prime` function checks whether the given number `n` is a prime number.

2. It first checks if the number is less than or equal to 1, in which case it returns False.

3. It then handles the case for the number 2 separately, as it is a prime number.

4. For odd numbers greater than 2, it iterates through odd divisors up to the square root of the number to check for divisibility.

5. If the number is divisible by any of these odd divisors, it returns False; otherwise, it returns True.

6. In the `main` function, the user is prompted to input a positive integer, and the result of the `is_prime` function is printed accordingly.

True
