graphics is very annoying, finish see this, what can set!
To see a basic graphics:
Enter a number greater than 2, the output of a hollow diamond,
Input:
3
Output:
*
* *
* *
* *
*
set a for loop? NO!!!!!!
attention! Bright artifact's time:
the problem solving skills: printing, step by step a good domain wide,
On the small 2, code! (of the new, the code is relaxed ) :

 
#include  
#include//setw () the header file 
using namespace std; 
Int n, num;//n is greater than the second number, num is number, n * 2-1 
Void the execute (int n)//print function, 
{
If (n==1)//special case, special processing, 
{
Cout} 
The else 
{
Coutfor(int i=1; i<=n - 2; I++)//cut turn tail and output space, 
{
Cout<" "; 
} 
Cout<" * "& lt; } 
} 
Int main () 
{
Cin> & gt; n; 
Num=2 * n - 1;//note that output diamond head office number is 2 * n - 1, the middle layer by space also have 2 * n - 1 characters, 
for(int i=1; i{
If (I % 2==1) with odd//total number can only in a row, 
{
Execute (I); 
} 
} 
For (int I=num - 2; i>=1; I -)//control num line after the number of rows, 
{
If (I % 2==1) 
{
Execute (I); 
} 
} 
return 0; 
//perfect end, 
} 

Post for the first time, if there is any mistake, forgive me,
