打印金字塔字母图案的C++程序

编写一个C++程序，使用for循环打印金字塔字母图案。

#include using namespace std;

int main() { int rows;

cout << "Enter Pyramid of Alphabets Rows = ";
cin >> rows;

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

int alphabet = 64;

for (int i = 1; i <= rows; i++)
{
	for (int j = 1; j <= rows - i; j++)
	{
		cout << " ";
	}
	for (int k = i; k > 0; k--)
	{
		cout << char(alphabet + k);
	}
	for (int l = 2; l <= i; l++)
	{
		cout << char(alphabet + l);
	}
	cout << "\\n";
}

}

这个C++例子使用while循环来打印金字塔的字母图案。if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[728,90],'tutorialgateway_org-medrectangle-4','ezslot_0',180,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-tutorialgateway_org-medrectangle-4-0') }。

#include using namespace std;

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

cout << "Enter Pyramid of Alphabets Rows = ";
cin >> rows;

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

alphabet = 64;
i = 1;

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

	k = i;
	while (k > 0)
	{
		cout << char(alphabet + k);
		k--;
	}

	l = 2;
	while (l <= i)
	{
		cout << char(alphabet + l);
		l++;
	}
	cout << "\\n";
	i++;
}

}

Enter Pyramid of Alphabets Rows = 15
