Answer:
Following are the program to this question:
#include <iostream>//defining header file
using namespace std;
void squareOfAsterisks(int x) //defining method squareOfAsterisks
{
int i,j; //defining integer variable
for(i=1;i<=x;i++) //defining loop to print column value
{
for(j=1;j<=x;j++) //defining loop to print row value
{
cout<<"*"; //print value
}
cout<<endl; //for line break
}
}
int main() //defining main method
{
int x; //defining integer variable
cout<<"Enter any number: "; //print message
cin>>x; //input value from user
squareOfAsterisks(x); //calling the method and pass the value
return 0;
}
Output:
Enter any number: 4

Explanation:
The description of the above program can be given as follows:
- In the given program a method "squareOfAsterisks" is declared, that accepts an integer value "x" in its arguments, inside the method two integer variable I, j is used, that uses a to print the given pattern.
- In the main method, an integer variable x is declared, which takes input from the user end, and then calls the method, that is "squareOfAsterisks" and passes its value.

Answer:
Option (D) using the private access specifier on the class fields
Explanation:
- The private access modifier can be used to hide the data.
- Methods and data variables ( fields ) can be declared with the private access modifier.
- Data hiding is a OOPS Concept which can be achieved with the private keyword (private access modifier).
- The access modifiers are of types Public, Private, Protected and Default ( no access modifier - no need to explicitly specify the default keyword).
- Data hiding means to hide the data, the data is contained in the class variables.So, option (d) using private access modifier on the class fields is correct option.
- Option (A) is wrong as the using the public access modifier doesn't hide anything. It is public and is visible to the public.
- Option (B) is wrong as using the private access modifier on the methods means it is hiding the implementation of the methods not the data.
- Option (C) is wrong as using private access modifiers on class definition means making the classes not visible to other classes it doesn't mean data hiding as the data is contained in the class variables.
