C 语言打印 V 星形图案程序

编写一个 C 语言程序，使用 for 循环打印 V 星形图案。

#include <stdio.h>

int main()
{

	int rows;

	printf("Enter V Shape Star Pattern Rows = ");
	scanf("%d", &rows);

	printf("Printing V Shape Star Pattern\n");

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

C 语言程序使用 while 循环打印星形 V 字形图案

#include <stdio.h>

int main()
{

	int i, j, k, l, rows;

	printf("Enter V Shape Star Pattern Rows = ");
	scanf("%d", &rows);

	printf("Printing V Shape Star Pattern\n");
	i = 1;
	while (i <= rows)
	{
		j = 1;
		while (j <= i)
		{
			printf("*");
			j++;
		}
		k = 1;
		while (k <= 2 * (rows - i))
		{
			printf(" ");
			k++;
		}
		l = 1;
		while (l <= i)
		{
			printf("*");
			l++;
		}
		printf("\n");
		i++;
	}
}

Enter V Shape Star Pattern Rows = 13

本 示例 使用 do while 循环打印字母 V 形星形图案。

#include <stdio.h>

int main()
{

	int i, j, k, l, rows;

	printf("Enter V Shape Star Pattern Rows = ");
	scanf("%d", &rows);

	printf("Printing V Shape Star Pattern\n");
	i = 1;
	do
	{
		j = 1;
		do
		{
			printf("*");

		} while (++j <= i);
		k = 1;
		while (k <= 2 * (rows - i))
		{
			printf(" ");
			k++;
		}
		l = 1;
		do
		{
			printf("*");
		} while (++l <= i);
		printf("\n");
	
	} while (++i <= rows);
}

Enter V Shape Star Pattern Rows = 16

在此示例中，ShapeVPattern 函数允许输入任何字符，并打印给定字符的字母 V 形图案。

#include <stdio.h>

void ShapeVPattern(int rows, char ch)
{
	for (int i = 1; i <= rows; i++)
	{
		for (int j = 1; j <= i; j++)
		{
			printf("%c", ch);
		}
		for (int k = 1; k <= 2 * (rows - i); k++)
		{
			printf(" ");
		}
		for (int l = 1; l <= i; l++)
		{
			printf("%c", ch);
		}
		printf("\n");
	}
}

int main()
{
	int rows;
	char ch;

	printf("Enter Character for V Pattern = ");
	scanf("%c", &ch);

	printf("Enter V Shape Star Pattern Rows = ");
	scanf("%d", &rows);

	printf("Printing V Shape Pattern\n");
	ShapeVPattern(rows, ch);
}

Enter Character for V Pattern = $
Enter V Shape Star Pattern Rows = 19
