Solution: 

 

#include <iostream>
using std::cout;
using std::cin;
using std::endl;
 
void square (int, char);
 
int main()
{
   int side;
   char fillCharacter;
 
   cout << "Enter side: ";
   cin >> side;
   cout << "Enter character: ";
   cin >> fillCharacter;
 
   square( side, fillCharacter );
   return 0;
}
 
//square function
void square( int side, char fillCharacter )
{
   for( int i = 1; i <= side; i++ )
   {
      for( int j = 1; j <= side; j++)
      {
         cout << fillCharacter;
      }
      cout << endl;
   }
}
