Explanation:

Search engine optimization (SEO) can be defined as a strategic process which typically involves improving and maximizing the quantity and quality of the number of visitors (website traffics) to a particular website by making it appear topmost among the list of results from a search engine such as Goo-gle, Bing, Yah-oo etc.

This ultimately implies that, search engine optimization (SEO) helps individuals and business firms to maximize the amount of traffic generated by their website i.e strategically placing their website at the top of the results returned by a search engine through the use of algorithms, keywords and phrases, hierarchy, website updates etc.

Hence, search engine optimization (SEO) is focused on improving the ranking in user searches by simply increasing the probability (chances) of a specific website emerging at the top of a web search.

Typically, this is achieved through the proper use of descriptive page titles and heading tags with appropriate keywords.

Generally, the conversion rate is mainly designed to be the highest for keyword searches classified as buyers because they're the main source of revenue for a business and by extension profits.

Answer:

Following are the solution to the given question:

import java.util.Scanner;//import package

public class AscendingAndDescending//defining a class AscendingAndDescending  

{

   public static void main(String[] args) //main method

   {

       int n1,n2,n3,min,max,m;

       Scanner in = new Scanner(System.in);//creating Scanner class object

       System.out.print("Enter an integer: ");//print message

       n1 = in.nextInt();//input value

       System.out.print("And another: ");//print message

       n2 = in.nextInt();//input value

       System.out.print("And just one more: ");//print message

       n3 = in.nextInt();//input value

       min = n1; //use min variable that holds value

       max = n1; //use mix variable that holds value

       if (n2 > max) max = n2;//use if to compare value and hols value in max variable

       if (n3 > max) max = n3;//use if to compare value and hols value in max variable

       if (n2 < min) min = n2;//use if to compare value and hols value in min variable

       if (n3 < min) min = n3;//use if to compare value and hols value in min variable

       m = (n1 + n2 + n3) - (min + max);//defining m variable that arrange value

       System.out.println("Ascending: " + min + " " + m + " " + max);//print Ascending order value

       System.out.println("Descending: " + max + " " + m + " " + min);//print Descending order value

   }

}

Output:

Enter an integer: 8

And another: 9

And just one more: 7

Ascending: 7 8 9

Descending: 9 8 7

Explanation:

In this program inside the main method three integer variable "n1,n2, and n3" is declared that inputs value from the user end and also defines three variable "min, max, and m" that uses the conditional statement that checks inputs value and assigns value according to the ascending and descending order and prints its values.

From method names, I am compelled to believe you are creating some sort of a Lexer object. Generally you implement Lexer with stratified design. First consumption of characters, then tokens (made out of characters), then optionally constructs made out of tokens.

Full question:

Provide the EXACT C++ line of code necessary to return the heap-dynamic variable ptr to the operating system.

Pokemon *ptr;

ptr = new Pokemon[6];

Answer:

delete ptr;

Explanation:

The command in the answer above deallocates memory(preventing memory leaks) and returns control to the operating system.

The command in the question dynamically allocates memory to the the heap(dynamically allocated memory is called heap) while the program is running(different from statically allocated memory that allocates before program compiles). When the variable is no longer needed, deallocation occurs using the command in our answer where the variable is deleted using the pointer(keeps track of dynamic variables).

Answer. Network

Explanation:

Answer:

A switch

Explanation:

A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a hub, a router, printer, a switch, etc.

In computer networking, a switch is a network hardware (device) that breaks up a network into separate collision domains within a single broadcast domain. Thus, it's commonly configured with virtual local area network (VLAN) to break up and interconnect multiple networks.

Answer:

in-memory.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.

In this context, data management is a type of infrastructure service that avails businesses (companies) the ability to store and manage corporate data while providing capabilities for analyzing these data.

Hence, a database management system (DBMS) is a system that enables an organization or business firm to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data.

Radom Access Memory (RAM) can be defined as the main memory of a computer system which allow users to store commands and data temporarily.

Generally, the Radom Access Memory (RAM) is a volatile memory and as such can only retain data temporarily.

All software applications temporarily stores and retrieves data from a Radom Access Memory (RAM) in computer, this is to ensure that informations are quickly accessible, therefore it supports read and write of files.

Generally, when a database stores the majority of data in random access memory (RAM) rather than in hard disks, it is referred to as an in-memory database (IMDB).

An in-memory database (IMDB) is designed to primarily to store data in the main memory of a computer system rather than on a hard-disk drive, so as to enhance a quicker response time for the database management system (DBMS).

Answer and Explanation:

Using Javascript programming language, to write this script we define a function that checks for empty variables with if...else statements and then uses a for loop to loop through all arguments passed to the function's parameters and print them out to the console.

function Check_Arguments(a,b,c){

var ourArguments= [];

if(a){

ourArguments.push(a);}

else( console.log("no argument for a"); )

if(b){

ourArguments.push(b);}

else( console.log("no argument for b"); )

if(c){

ourArguments.push(c);}

else( console.log("no argument for c"); )

for(var i=0; i<ourArguments.length; i++){

Console.log(ourArguments[i]);

}

Following are the code to the given question:

#include <iostream>//header file

using namespace std;

int main()//main method

{

int runTimes[] = {800, 775, 790, 805, 808};//defining array of integer

for(int x=0;x<3;x++)//defining for loop to print three element of array value

{

printf("%d\n",runTimes[x]);//print array value  

}

return 0;

}

Output:

Please find the attached file.

Explanation:

In this code, an array integer "runTimes" is declared that holds the given array values, and in the next step, a for loop is declared.

Inside the loop, an integer variable x is declared that starts from 0 and ends when its value less than 3 in which we print the first three array element values.

Answer:

Hence the answer is given as follows,

Explanation:

Base Case:-  

If (num == 0) //This is the base case for the given recursive method  

return 1;  

If(num % 2!=0) checks whether num is odd.  

The above condition is true for all odd numbers and false for even numbers.  

if the remainder is not equal to zero when we divide the number with 2 then it is odd.  

The method:-  

The above recursive method calculates the product of odd numbers up to the given range(that is num)  

For num=5   => 15(5*3*1).  

For num=7   => 105(7*5*3*1).  

For num=10 => 945(9*7*5*3*1).

Answer: suck

Explanation:

Answer:

The program in Python is as follows:

name = input("Name of item: ")

PoundPrice = int(input("Pound Price: "))

Pounds = int(input("Weight (pounds): "))

Ounces = int(input("Weight (ounce): "))

UnitPrice = PoundPrice/16

TotalPrice = PoundPrice * (Pounds + Ounces/16)

print("Unit Price:",UnitPrice)

print("Total Price:",TotalPrice)

Explanation:

This gets the name of the item

name = input("Name of item: ")

This gets the pound price

PoundPrice = int(input("Pound Price: "))

This gets the weight in pounds

Pounds = int(input("Weight (pounds): "))

This gets the weight in ounces

Ounces = int(input("Weight (ounce): "))

This calculates the unit price

UnitPrice = PoundPrice/16

This calculates the total price

TotalPrice = PoundPrice * (Pounds + Ounces/16)

This prints the unit price

print("Unit Price:",UnitPrice)

This prints the total price

print("Total Price:",TotalPrice)
