Disk Defragmenter
A disk defragmenter is a utility that reorganizes the files and unused space on a computer's hard disk so that the operating system accesses data more quickly and programs run faster.
Answer:
// This program is written in C++
// Comments are used for explanatory purpose
// Program starts here
#include<iostream.h>
#include<stdlib.h>
int main()
{
// Declare variables
int num, selectno;
string status;
randomize();
//Generate random number;
num=rand()%10000;
// Prompt to guess a number
cout<<"You have only 10 tries\nTake a guess: ";
int tries = 0;
while (tries != 10)
{
cin>>selectno;
if(selectno == num){
cout<<"You passed at the "<<count+1<<" attempt";
tries = 10;
}
else
{
cout<<"You failed. Take another guess\n You have "<<10 - count + 1 <<" attempts";
}
tries++;
if(tries >= 10)
{
break;
}
}
return 0;
}
Answer:
//here is code in java.
import java.util.*;
class Solution
{
// main method of class
public static void main (String[] args) throws java.lang.Exception
{
try{
// declare an initialize first string variables
String st1="hello";
// declare an initialize first string variables
String st2="world";
// create another string variable
String st3;
// exchange the value of both string variables
st3=st1;
st1=st2;
st2=st3;
System.out.println("value of first String after exchange: "+st1);
System.out.println("value of second String after exchange: "+st2);
}catch(Exception ex){
return;}
}
}
Explanation:
declare and initialize two string variables.Create another string variable "st3". first assign value of "st1" to "st3" after then value of "st2" to "st1" and then assign value of "st3" to "st2". This will exchange the values of both the string.
Output:
value of first String after exchange: world
value of second String after exchange: hello
Answer:
In computing, extract, transform, load (ETL) is the general procedure of copying data from one or more sources into a destination system which represents the data differently from the source(s) or in a different context than the source(s).
Data extraction involves extracting data from homogeneous or heterogeneous sources; data transformation processes data by data cleansing and transforming them into a proper storage format/structure for the purposes of querying and analysis; finally, data loading describes the insertion of data into the final target database such as an operational data store, a data mart, data lake or a data warehouse. Hope this helps! PLEASE GIVEE ME BRAINLIST!!! =)
