打印倒三角数字图案的C++程序

编写一个C++程序，使用for循环打印倒三角数字模式。

#include using namespace std;

int main() { int rows;


cout << "Enter Inverted Triangle Number Pattern Rows = ";
cin >> rows;

cout << "Inverted Triangle Number Pattern\\n";

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

#include using namespace std;

int main() { 
int rows, i, j, k;


cout << "Enter Inverted Triangle Number Pattern Rows = ";
cin >> rows;

cout << "Inverted Triangle Number Pattern\\n";
i = 1;

while (i <= rows)
{
	j = 1;
	while (j < i)
	{
		cout << " ";
		j++;
	}

	k = 1;
	while (k <= rows - i + 1)
	{
		cout << k << " ";
		k++;
	}
	cout << "\\n";
	i++;
}

Enter Inverted Triangle Number Pattern Rows = 9
Inverted Triangle Number Pattern
1 2 3 4 5 6 7 8 9 
 1 2 3 4 5 6 7 8 
  1 2 3 4 5 6 7 
   1 2 3 4 5 6 
    1 2 3 4 5 
     1 2 3 4 
      1 2 3 
       1 2 
        1 

这个C++例子使用do while循环显示数字的倒三角模式。

#include using namespace std;

int main() { int rows, i, j, k;

cout << "Enter Inverted Triangle Number Pattern Rows = ";
cin >> rows;

cout << "Inverted Triangle Number Pattern\\n";
i = 1;

do
{
	j = 1;
	do
	{
		cout << " ";

	} while (j++ < i);

	k = 1;
	do
	{
		cout << k << " ";

	} while (++k <= rows - i + 1);

	cout << "\\n";

} while (++i <= rows);

Enter Inverted Triangle Number Pattern Rows = 6
Inverted Triangle Number Pattern
 1 2 3 4 5 6 
  1 2 3 4 5 
   1 2 3 4 
    1 2 3 
     1 2 
      1
