Write code that prints: Ready! firstNumber ... 2 1 Run! Your code should contain a for loop. Print a newline after each number and after each line of text. Ex: If the input is: 3 the output is: Ready! 3 2 1 Run!
Answer:
Explanation:
The following code is written in Java. It asks the user to enter the first number. Then it saves that number in a variable called firstNumber. It then uses that number to loop backwards from that number to 1 and goes printing out the countdown text. A test case has been created and the output can be seen in the attached image below.
import java.util.Scanner;

Write a program that defines an array of integers and a pointer to an integer. Make the pointer point to the beginning of the array. Then, fill the array with values using the pointer (Note: Do NOT use the array name.). Enhance the program by prompting the user for the values, again using the pointer, not the array name. Use pointer subscript notation to reference the values in the array.
Answer:
#include<iostream>
using namespace std;
int main()
{
int a[20],n;
int *p;
cout<<"\n enter how many values do you want to enter:";
cin>>n;
for(int i=0;i<n;i++)
{
cout<<"\n Enter the "<<i+1 <<"th value :";
cin>>*(p+i);
//reading the values into the array using pointer
}
cout<<"\n The values in the array using pointer is:\n";
for(int i=0;i<n;i++)
{
cout<<"\n (p+"<<i<<"): "<<*(p+i);
//here we can use both *(p+i) or p[i] both are pointer subscript notations
}

Daniella is configuring a Wi-Fi network in a restaurant for access by staff and customers. How far does WiFi, the broadband wireless technology that allows computers and other devices to communicate over a wireless signal typically travel indoors in the form of radio waves?
a. 1000 feet
b. 300 feet
c. 120 feet
d. 500 feet
Answer:
c. 120 feet
Explanation:
WiFi can be defined as a wireless local area network that allows network devices such as access points (APs), computers (both laptops and desktops), smartphones, smart televisions, etc., to communicate with each other wirelessly over a short-ranged network. It is a standard communication network that uses radio waves to establish a channel (medium) between multiple network devices.
This ultimately implies that, the network range or distance covered by WiFi is largely dependent on transmission power and frequency. The standard range or distance covered by WiFi is about 50 meters (160 feet).
Hence, a WiFi traveling indoors in the form of radio waves and operating on the 2.4 GHz band would cover up to a distance of 150 feet. Also, a WiFi can reach or travel up to 300 feet outdoors.
In this scenario, the WiFi network Daniella is configuring in a restaurant for access by staff and customers can go as far as 120 feet indoors.

Answer:
a. it designs its own applications but doesn't customize the operating system.
Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
Cloud computing comprises of three (3) service models and these are;
1. Infrastructure as a Service (IaaS).
2. Software as a Service (SaaS).
3. Platform as a Service (PaaS).
Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.
The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.
Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).
Some of the advantages of Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.
Basically, platform as a Service (PaaS) providers (vendors) usually provide their clients (software developers) with server and data storage, operating system, data center, networking resources, etc., while the software developers design, deploy and manage their software applications.
Hence, a business should choose the platform as a service (PaaS) cloud model when it designs its own applications but doesn't customize the operating system.
What does the AVERAGE function calculate? the total sum of a list of values the arithmetic mean of a list of values the total number of values in a list the percentage of values in a list
Answer:
B) the arithmetic mean of a list of values
Explanation:
on Edge
The Average function calculates the arithmetic mean of a list of values. Therefore, option B is the correct option.
What is the average?In its most general definition, an average can be considered as the representative number or figure from the whole list. The average of a list containing multiple values is obtained by adding all the values and dividing them up by the total number of values.
The ultimate objective of calculating the average is to discover the value that represents the whole list. Average is also known as mean, and it works as a central value in the list, which is comprehensive in nature. It works as an approximate or rough estimate, which helps us in making decisions in daily life.
Thus, the average function calculates the arithmetic mean of a list of values. Therefore, option B is the correct option.

Explanation:
you just multiply.
The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() method, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1.
Ex: If the input is: 7
the out put is :fibonacci(7) is 13
import java.util.Scanner;
public class LabProgram {
public static int fibonacci(int n) {
/* Type your code here. */
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int startNum;
System.out.println("Enter your number: ");
startNum = scnr.nextInt();
System.out.println("fibonnaci(" + startNum + ") is " + fibonacci(startNum));
}
}
You could use recursion to write java method for computing fibonacci numbers. Though it will be inefficient for n > about 50, it will work.
public static int fibonacci(int n) {
if (n < 0) { return -1; }
if (n < 2) { return n; }
else { return fibonacci(n-1)+fibonacci(n-2); }
}
Hope this helps.
The current term of a Fibonacci series is derived by adding the two previous terms of its sequence; and the first two terms are 0 and 1.
The code segment (without comments) that completes the program is as follows:
int T1 = 0, T2 = 1, cT;
if (n < 0){
return -1; }
for (int i = 2; i <= n; i++) {
cT = T1 + T2;
T1 = T2;
T2 = cT; }
return T2;
With comments (to explain each line)
/*This declares the first term (T1), the second term (T2) and the current term (CT).
T1 and T2 are also initialized to 0 and 1, respectively
*/
int T1 = 0, T2 = 1, cT;
//This returns -1, if n is negative
if (n < 0){ return -1;
}
//The following iterates through n
for (int i = 2; i <= n; i++) {
//This calculates cT
cT = T1 + T2;
//This passes T2 to T1
T1 = T2;
//This passes cT to T2
T2 = cT;
}
//This returns the required term of the Fibonacci series
return T2;
At the end of the program, the nth term of the series would be returned to the main method for output.

You are hired as an IT consultant for the government owned mobile operating company, Teletalk. Based on the following scenario, make a report for the decision makers to resolve the stated problems.
Despite aggressive campaigns to attract customers with lower call rates and internet packages, Teletalk has been losing a large number of its subscribers (users). Management wants to know why so many customers are leaving Teletalk and what can be done to attract them back. Are customers deserting because of poor customer service, uneven network coverage, wireless service charges, or competition from other mobile operators with extra services (GP/BL)? How can the company use information systems to help find the answer? What management decision could be made using information from these systems? What competitive strategy Teletalk can develop using information systems and how?
Answer:
An IT consulting report may be a transcript created via an IT professional that addresses all the possible aspects of an enterprise or a corporation. It is often an aggressive analysis report, Project reputation report, Business Plan report, or a Supply Chain Model file
Let's see how to write this kind of report

When a Select Case statement executes, the value of the test expression is compared with the values that follow each of the _______ keywords.
Answer:
Case
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
A Select Case statement can be defined as a conditional statement that avails software developers or programmers the ability to test a variable by comparing it with a list of values.
In a Select Case statement, each variable is referred to as a Case.
Generally, when a Select Case statement executes, the value of the test expression is compared with the values that follow each of the Case keywords.
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain fewer than 20 integers.
Answer:
Ex: If the input is:
5 50 60 140 200 75 100
the output is:
50 60 75
The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.
For coding simplicity, follow every output value by a space, including the last one.
Such functionality is common on sites like Amazon, where a user can filter results.

Cloud computing can be defined as a form of data computing which requires the use of shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offer individuals and businesses a fast, secured, effective and efficient way of providing services over the internet.
Basically, cloud computing comprises three (3) service models and these include;
1. Platform as a Service (PaaS).
2. Software as a Service (SaaS).
3. Infrastructure as a Service (IaaS).
Additionally, the two (2) main characteristics of cloud computing are;
I. Measured service: it allows cloud service providers to monitor and measure the level of service used by various clients with respect to subscriptions.
II. Resource pooling: this allows cloud service providers to serve multiple customers or clients with services that are scalable and provisional.
For example, the provisioning of On-demand computing resources such as storage, network, virtual machines (VMs), etc., so as to enable the end users install various software applications, database and servers.
Hence, the technology that could be combined by the small e-commerce company with its current automated processes is cloud storage.
There are different tools used in data sharing. The technology that could be combined with their current automated processes to do this is blockchain.
Blockchain is known to use different kinds of distributed ledger that is often shared across networked devices. Through this, people on the network can share files and values securely and even on a peer-to-peer basis. This is no need any middlemen.
