打印金字塔数字图案的C++程序

编写一个C++程序，使用for循环打印金字塔数字模式。

#include using namespace std;

int main() { int rows;


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

cout << "Printing Pyramid Number Pattern\\n";

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

#include using namespace std;

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


cout << "Enter Rows = ";
cin >> rows;

cout << "Printing\\n";
i = 1;

while (i <= rows)
{
	j = rows;
	while (j > i)
	{
		cout << " ";
		j--;
	}

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

	cout << "\\n";
	i++;
}

Enter Rows = 8
Printing
       1 
      2 2 
     3 3 3 
    4 4 4 4 
   5 5 5 5 5 
  6 6 6 6 6 6 
 7 7 7 7 7 7 7 
8 8 8 8 8 8 8 8 

这个C++例子使用do while循环显示数字的金字塔模式。

#include using namespace std;

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


cout << "Enter Rows = ";
cin >> rows;

i = 1;

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

	} while (j-- > i);

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

Enter Rows = 9

         1 
        2 2 
       3 3 3 
      4 4 4 4 
     5 5 5 5 5 
    6 6 6 6 6 6 
   7 7 7 7 7 7 7 
  8 8 8 8 8 8 8 8 
 9 9 9 9 9 9 9 9 9
