Answer:
#include <iostream>
using namespace std;
int main() {
   int k;
double d;
string s;
cin >> k >> d >> s;
cout << s << " " << d << " " << k << "\n" << k << " " << d << " " << s; }
                                                                    
Explanation:
k is int type variable that stores integer values.
d is double type variable that stores real number.
s is string type variable that stores word.
cin statement is used to take input from user. cin takes an integer, a real number and a word from user. The user first enters an integer value, then a real number and then a small word as input. 
cout statement is used to display the output on the screen. cout displays the value of k, d and s which entered by user. 
First the values of k, d and s are displayed in reverse order. This means the word is displayed first, then the real number and then the integer separated again by EXACTLY one space from each other. " " used to represent a single space.
Then next line \n is used to produce a new line. 
So in the next line values of k, d and s are displayed in original order (the integer , the real, and the word), separated again by EXACTLY one space from each other.
The program along with the output is attached. 
 
        
             
        
        
        
Answer:
3. Granularity
Explanation:
Granularity's concept is representing the level of how do we store the data in our database.
If the data are detailed, we can resume the data until get a granularity more strong for our analysis.
For example:
We could store data year by year of our costumers, if want to get more granularity, we could store data month by month, also we could get specific data like how often our customers visit the business or how often our customers buy in a category product.
 
        
             
        
        
        
Answer:
Option B is Correct.
Explanation:
Thermal paste is used in the CPU motherboard to reduce the heat.
Thermal paste is a heat observing coating that is used to make the system cool when it is heated much by working for a long time.
Thermal paste is also used in heat sink in CPU and CPU passes the air in the heat sink to make the temperature normal.
Thermal paste is very useful which installing any processor otherwise which running, the temperature will be increased in the absence of the thermal paste.
It is used to maintain the empty place between the motherboard and the processor.
