For reference graph is easy,

 
#include  
using namespace std; 

Int main (void) 
{
Int I, j, k, n; 
Cin & gt; & gt; n; 
For (I=n; i>=1; I -) 
{
For (j=1; J<=n - (I); J++) 
{
Cout & lt; <""; 
} 
For (k=1; K<=I * 2-1; K++) 
{
Cout & lt; } 
Cout & lt; } 
For (I=2; I<=n; I++) 
{
For (j=0; J{
Cout & lt; <""; 
} 
For (k=1; K<=I * 2-1; K++) 
{
Cout & lt; } 
Cout & lt; } 

return 0; 
}
