用C++程序打印倒置的V型星形图案

编写一个C++程序，使用for循环打印倒置的V型星形图案或方形星形图案内的半个钻石。

#include using namespace std;

int main() { int rows;


cout << "Enter Inverted V Shape Star Pattern Rows = ";
cin >> rows;

cout << "Printing Inverted V Shape Star Pattern\\n";

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

#include using namespace std;

int main() { int rows;


cout << "Enter Inverted V Shape Star Pattern Rows = ";
cin >> rows;

cout << "Inverted V Shape Star Pattern\\n";

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

Enter Inverted V Shape Star Pattern Rows = 12

使用do while循环打印倒V星形图案的C++程序

#include using namespace std;

int main() { int i, rows;


cout << "Enter Inverted V Shape Star Pattern Rows = ";
cin >> rows;

cout << "Inverted V Shape Star Pattern\\n";

i = rows;
do
{
	int j = 1;
	do
	{
		cout << "\*";

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

Enter Inverted V Shape Star Pattern Rows = 15

在这个C++模式的例子中，InvertedVShapePatternFun允许输入任何字符，并显示给定字符的倒V。

#include using namespace std;

void InvertedVShapePatternFun(int rows, char ch)
{
	for (int i = rows; i >= 1; i--)
	{
		for (int j = 1; j <= i; j++)
		{
			cout << ch;
		}
		for (int k = 1; k <= 2 * (rows - i); k++)
		{
			cout << " ";
		}
		for (int l = 1; l <= i; l++)
		{
			cout << ch;
		}
		cout << "\n";
	}
}
int main() { int rows; char ch;


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

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

cout << "Inverted V Shape Star Pattern\\n";
InvertedVShapePatternFun(rows, ch);

Enter Character for Inverted V Pattern = $
Enter Inverted V Shape Star Pattern Rows = 17
