#include<stdio.h>
void main()
{
int n=3;
int i,a,b;
        //.上半部分
        for( i=1;i<=n;i++)//控制行数
        {
            for(  a=n-1;a>=i;a--)//打印空格
            {
                printf(" ");
            }
            for(  b=1;b<=2*i-1;b++)//打印*
            {
                printf("*");
            }
            printf("\n");
        }
        //下半部分
        for( i=n-1;i>=1;i--)
        {
            for( a=i;a<=n-1;a++)
            {
                printf(" ");
            }
            for( b=1;b<=2*i-1;b++)
            {
                printf("*");
