#include
using namespace std;

void square( int ); // function prototype

int main()
{
int side; // input side length

cout << "Enter side: ";
cin >> side;
cout << '\n';

square( side ); // display solid square of asterisks
cout << endl;
} // end main
// square displays solid square of asterisks with specified side
void square( int side )
{
// loop side times for number of rows
for ( int row = 1; row <= side; row++ )
{
// loop side times for number of columns
for ( int col = 1; col <= side; col++ )
cout << '*';

cout << '\n';
} // end for
} // end function square
