3. Write a method squareOfAsterisks that displays a solid square (the same number of rows and columns) of asterisks whose side is specified in integer parameter side. For example, if side is 4, the method should displayIncorporate this method into an application that reads an integer value for side from the user and outputs the asterisks with the squareOfAsterisks method.

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:
