C语言上下金字塔

用上一道金字塔题来思考

#include <stdio.h>

int main()

{

int n = 0;
while (scanf("%d", &n)!=EOF)
{

	for (int i = 1; i <= n; i++)
	{
		for (int j = 1; j <= n - i; j++)
		{
			printf(" ");
		}
		for (int k = 1; k <= 2 * i - 1; k++)
		{
			printf("*");
		}
		printf("\n");

	}

	for (int i = 2; i <= n; i++)
	{
		

		for (int k = 1; k <=i-1; k++)
		{
			printf(" ");
		}
        for (int j = 1; j <=2*n-(2*i-1); j++)
		{
			printf("*");
		}

		printf("\n");

	}

}

}
