好东西,绝对是好东西,我向大家推荐

#include <iostream.h>
int main()
{
	int i,j,a[18][18],is,js,ie,je,s;
	for(i=0;i<18;i++)
	{
		for(j=0;j<18;j++)
		{
			a[i][j]=0;
		}
	}
	int n;
	while(cin>>n)
	{
		is=0;js=0;ie=2*n-1;je=ie;s=ie;
		while(is<=ie)
		{
			for(i=is;i<ie;i++)
			{
				for(j=js;j<je;j++)
				{
					a[i][j]=is;
				}
				
			}
			is++;js++;ie--;je--;
		}
		for(i=0;i<s;i++)
		{
			for(j=0;j<s;j++)
			{
				if(a[i][j]==0) cout<<"A";
				if(a[i][j]==1) cout<<"B";
				if(a[i][j]==2) cout<<"C";
				if(a[i][j]==3) cout<<"D";

				if(a[i][j]==7) cout<<"H";
				if(a[i][j]==8) cout<<"I";
				if(j!=s-1) cout<<" ";
				
			}
			cout<<endl;
		}
	}
