Answer:

The expressions in each part of an AND or OR expression use <u>Short Circuit</u> evaluation; that is, they are evaluated only as much as necessary to determine whether the entire expression is true or false.

Explanation:

Logic operations follow different type of evaluation methods that can be short circuit or open circuit evaluation. In short circuit evaluation if first operand of the expression is true or false in OR or AND operation respectively, the result will found as true or false without checking the second operand of the expression. This is called Short Circuit Evaluation.

In OR operation, If first operand is true it means that the result of the expression is true without knowing that the other operand is true or false. In AND operation, If the first operand is False, the result will found as False without knowing that whether the 2nd operand is  true or false.

This Mechanism is called Short Circuit Evaluation.

Novosadov [1.4K]

Answer:

Check the explanation

Explanation:

  1. CPU utilization and response time: CPU utilization is amplified if the overheads that are connected with context switching or alternating are minimized. The context switching outlay can be reduced by performing context switches occasionally. This could on the other hand lead to increasing the response time for processes.
  2. The Average turnaround time and maximum waiting time: Average turnaround time is reduced by implementing the shortest or simple tasks first. Such a scheduling and arrangement strategy could nevertheless starve long-running tasks and in so doing boost their overall waiting time.
  3. I/O device utilization and CPU utilization: CPU utilization is maximized by executing a list of long-running CPU-bound tasks not including the performing context switches. This is maximized by setting up I/O-bound tasks as early as they become ready to run, thus sustaining the overheads of context switches.

What is the output of this code? import java.util.HashSet; class A { public static void main(String[ ] args) { HashSet set = new
kompoz [17]

Answer:

The code will give an error that is "At least one public class is required in main file".

Explanation:

In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:

Program:

import java.util.HashSet; //import package

public class A  //define class as public.

{

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

   {

       HashSet set = new HashSet(); //creating hashset object.

       set.add("A"); //add alphabet in hashset

       set.add("B"); //add alphabet in hashset

       set.add("C"); //add alphabet in hashset

       System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.

   }

}

Output:

Size of HashSet is : 3

Explanation of the program:  

  • In the above program, we define a public class that is "A" and inside the class, we define the main method.  
  • Inside the main method, we create a HashSet class object that is "set".  
  • To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.

Write a program that reads in an integer, and breaks it into a sequence of individual digits. Display each digit on a separate l
Montano1993 [528]

Answer:

The program in Python is as follows:

num = int(input())

for i in str(num):

   print(int(i))

Explanation:

This gets input for the number

num = int(input())

This converts the number to string and iterates through each element of the string

for i in str(num):

This prints individual digits

   print(int(i))

yarga [219]

Answer:

The correct answer is "Program".  

Explanation:

Program is the collection of statement or instruction which is developed for creating any software or any purpose. The program is implemented or executed by a computer to perform a particular task.The particular programmer always writes an instruction to develop a program.

Program are always organized for the common purpose, that specifies the computer what tasks to perform as well as how to perform that particular task for example if programmer develops a program of calculator then it should be only used for the calculation purpose.
