编程菱形图案

在这里插入代码片
```#include<stdio.h>
#include
#pragma warning(disable:4996)
#include 
#include
int main()
{
	int i, j, n;
	printf("\nPlease Enter n:");
	scanf("%d", &n);
	for (i = 1; i <= n; i++)
	{
		for (j = 1; j <= n - i; j++)
			printf(" ");
		for (j = 1; j <= 2 * i - 1; j++)
			printf("*");
		printf("\n");
	}
	for (i = n-1; i >=0; i--)
	{
		for (j = 1; j <= n - i; j++)
			printf(" ");
		for (j = 1; j <= 2*i-1; j++)
			printf("*");
		printf("\n");
	}
			
	system("pause");
	return 0;
