This statement checks if num1 is equal to the absolute value of num1

For instance,

num1 = 4 and the absolute value of num1 = 4. This would run the code inside the if statement but if num1 = -1 the absolute value of num1 = 1 and the if stamtent would be skipped because -1 does not equal 1

Monster Collector

Lera25 [3.4K]

Answer:

In java:

import java.util.*;

public class Main{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int monsternum, usernum;

int count = 0;

Random rand = new Random();

String [] monsters = {"wild pikamoo","wild bulbaroar"};

for(int i =0;i<2;i++){

monsternum = rand.nextInt(5);

System.out.print("A "+monsters[i]+" appears! Guess a number between 1 and 5: ");

usernum = input.nextInt();

if(monsternum == usernum){ count++; System.out.println("Congratulations, you caught a "+monsters[i]+"!"); }

else{ System.out.println("You almost had it, but the monster escaped."); }

}

System.out.println("There are no more monsters to encounter!");

System.out.println("You caught "+count+" monsters of 2");

if(count!=2){ System.out.print("Keep training to be the very best!"); }

else{ System.out.print("You're the monster collector master!"); }

}

Explanation:

This declares monster and user number as integers

int monsternum, usernum;

Initialize count to 0

int count = 0;

Call the random object

Random rand = new Random();

Create a string array to save the monster names

String [] monsters = {"wild pikamoo","wild bulbaroar"};

Iterate for the 2 monsters

for(int i =0;i<2;i++){

Generate a monster number

monsternum = rand.nextInt(5);

Prompt the user to take a guess

System.out.print("A "+monsters[i]+" appears! Guess a number between 1 and 5: ");

Get user guess

usernum = input.nextInt();

If monster number and user guess are equal, congratulate the user and increase count by 1

if(monsternum == usernum){ count++; System.out.println("Congratulations, you caught a "+monsters[i]+"!"); }

If otherwise, prompt the user to keep trying

else{ System.out.println("You almost had it, but the monster escaped."); }

}

Print no monsters again

System.out.println("There are no more monsters to encounter!");

Print number of monsters caught

System.out.println("You caught "+count+" monsters of 2");

Print user score

if(count!=2){ System.out.print("Keep training to be the very best!"); }

else{ System.out.print("You're the monster collector master!"); }

Unlike the GUI (Graphical User Interface), the CLI uses a very easy mechanism which is not user friendly.

2. The answer is carry electrical current

Transistors are semiconductor devices used to control the flow of electricity in circuits. They contain three layers of silicon that are used to amplify or switch electric currents. They are very fundamental in modern electronic devices and are considered one of the greatest inventions in modern history. In small quantities, transistors are used to make simple switches and digital logic. In huge quantities, transistors are interconnected and combined into small chips that create complex ICs, computer memories, and processors.

3. The answer is True

A peripheral device such as a keyboard, a mouse, or a printer is a hardware input or output device that gives the computer additional functionalities and serve as an auxiliary computer device. They are commonly known as I/O devices because they provide input and output information for the computer.

4. The answer is A: Interacts with or sends data to the computer

A peripheral device as mentioned above is used to input information into and get it out of the computer. In addition, an input device sends data, information, or instructions to the computer.
