write a script to check command arguments. Display the argument one by one (use a for loop). If there is no argument provided, remind users about the mistake.
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]);

Explanation:
A recursive method may call other methods, including calling itself. A recursive method has:
1. a base case -- a case that returns a value or exits from a method without performing a recursive call.
2. a recursive case -- calling the method again with a smaller case..
Study the recursive method given below.
For example, this call recursiveMethod (5); returns 15:
public static int recursiveMethod (int num) (
if (num == 0)
return 1;
else {
if (numX2!=0)
return num * recursiveMethod (num -1);
else
return recursiveMethod (num-1);
}
}
1 What is the base case?
2. What does the following statement check?
3. What does the method do?
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).

g 1-1 Which network model layer provides information about the physical dimensions of a network connector like an RJ45
Answer:
Physical layer
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer
2. Data link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer
Each layer has its unique functionality which is responsible for the proper functioning of the communication services.
In the OSI model, the physical layer is the first and lowest layer. Just like its name physical, it addresses and provides information about the physical characteristics such as type of connector, cable type, length of cable, etc., of a network.
This ultimately implies that, the physical layer of the network (OSI) model layer provides information about the physical dimensions of a network connector such as a RJ45. A RJ45 is used for connecting a CAT-5 or CAT-6 cable to a networking device.
When a database stores the majority of data in RAM rather than in hard disks, it is referred to as a(n) _____ database.
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).

Sample output with input: '1 2 3,2 4 6,3 6 9':
1 | 2 | 3
2 | 4 | 6
3 | 6 | 9
How can I delete that whitespace?
Answer:
The program is as follows:
[tex]mult\_table = [[1, 2, 3], [2, 4, 6], [3, 6, 9]][/tex]
count = 1
for row in mult_table:
for item in row:
if count < len(row):
count+=1
print(item,end="|")
else:
print(item)
count = 1
Explanation:
This initializes the 2D list
[tex]mult\_table = [[1, 2, 3], [2, 4, 6], [3, 6, 9]][/tex]
This initializes the count of print-outs to 1
count = 1
This iterates through each rows
for row in mult_table:
This iterates through each element of the rows
for item in row:
If the number of print-outs is less than the number of rows
if count < len(row):
This prints the row element followed by |; then count is incremented by 1
count+=1
print(item,end="|")
If otherwise
else:
This prints the row element only
print(item)
This resets count to 1, after printing each row
count = 1
To delete the whitespace, you have to print each element as: print(item,end="|")
See that there is no space after "/"
Answer:
count = 1
for row in mult_table:
for item in row:
if count < len(row):
count+=1
print(item,end=" | ")
else:
print(item)
count = 1

{
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.
Write a java program that reads a list of integers and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one. Assume that the list will always contain fewer than 20 integers.
Ex: If the input is:
5 2 4 6 8 10
the output is:
10,8,6,4,2,
To achieve the above, first read the integers into an array. Then output the array in reverse.
Answer:
Explanation:
using namespace std;
#include <iostream>
int Go()
{
int N;
int A[20];
cout << " How many integers do you have ??? :>";
cin >> N;
if (N>20) { N=20; }
for (int iLoop=0; iLoop<N; iLoop++)
{
cout << "Input integer # " << (iLoop+1) << " :>";
cin >> A[iLoop];
}
for (int iLoop=N-1; iLoop>=0; iLoop--)
{
cout << A[iLoop] << " ";
}
cout << endl;
}
int main()
{
Go();
}
A Java program that reads a list of integers and outputs them in reverse is written as,
import java.util.Scanner;
public class ReverseList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of integers
int numIntegers = scnr.nextInt();
// Create an array to store the integers
int[] integers = new int[numIntegers];
// Read the integers into the array
for (int i = 0; i < numIntegers; i++) {
integers[i] = scnr.nextInt();
}
// Output the integers in reverse order
for (int i = numIntegers - 1; i >= 0; i--) {
System.out.print(integers[i]);
// Add comma unless it's the last integer
if (i > 0) {
System.out.print(",");
}
}
System.out.println(); // Add a new line at the end
}
}
Given that,
Write a Java program that reads a list of integers and outputs those integers in reverse.
Here, The input begins with an integer indicating the number of integers that follow.
For coding simplicity, follow each output integer by a comma, including the last one.
So, A Java program that reads a list of integers and outputs them in reverse:
import java.util.Scanner;
public class ReverseList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of integers
int numIntegers = scnr.nextInt();
// Create an array to store the integers
int[] integers = new int[numIntegers];
// Read the integers into the array
for (int i = 0; i < numIntegers; i++) {
integers[i] = scnr.nextInt();
}
// Output the integers in reverse order
for (int i = numIntegers - 1; i >= 0; i--) {
System.out.print(integers[i]);
// Add comma unless it's the last integer
if (i > 0) {
System.out.print(",");
}
}
System.out.println(); // Add a new line at the end
}

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).
What is the default return type of a method in Java language?
A.Void
B.Int
C.None
D.Short
Answer:
The default return data type in function is int
Answer: Option (b)
Explanation:
The default return data type in a function is int. In other words commonly if it is not explicitly mentioned the default return data type of a function by the compiler will be of an integer data type.
If the user does not mention a return data type or parameter type, then C programming language will inevitably make it an int.
