For and If statement

Subject: Using “For” and “If” statement to produce a square.


Hello,

Working my way through some excises. One of the tasks is to draw a square( not rocket science I know).
I can produce the square, but I’m sure there is a more efficient means.

Some pointers please!

Code:
#include <iostream.h>

void drawSquare(int x);

int main ()
{
drawSquare(20);
return 0;
}

void drawSquare(int x )
{
for (int a =1 ; a <=x ; a++)
for (int b =1; b <=x;b++)
if (a==1 || a==x ) cout << "a" ;
else
if (a==2 && b==1) cout << "\n" << "b";
else
if(b>1 && b< x) cout << " ";
else
if (b ==1)cout <<"b";
else
cout <<"b"<<"\n";

Thanks

I hope this helps:

#include <iostream.h> 

void drawSquare(int x); 

int main () 
{ 
drawSquare(20); 
return 0; 
} 

void drawSquare(int x ) 
{ 
	for (int a =1 ; a <=x ; a++) 
	{
		for (int b =1; b <=x;b++) 
		{
			if (a==1 || a==x)
				cout<<"a";
			else
			{
				if (b==1 || b==x)			
					cout<<"b";
				else
					cout<<" ";
			}
		}
		cout<<"\n";
	}
};

Thanks Chris! A lot cleaner way of achieving it
