C++ 程序打印镜像字母图案的直角三角形

编写一个 C++ 程序，使用 for 循环打印镜像字母图案的直角三角形。

#include<iostream>
using namespace std;

int main()
{
	int rows;

	cout << "Enter Right Triangle of Mirrored Alphabets Rows = ";
	cin >> rows;

	cout << "The Right Triangle of Mirrored Alphabets Pattern\n";

	int alphabet = 65;

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

此 C++ 示例 使用 while 循环打印镜像字母的直角三角形图案。

#include<iostream>
using namespace std;

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

	cout << "Enter Right Triangle of Mirrored Alphabets Rows = ";
	cin >> rows;

	cout << "The Right Triangle of Mirrored Alphabets Pattern\n";

	alphabet = 65;
	i = 0;

	while (i <= rows - 1)
	{
		j = 0;
		while (j <= i)
		{
			cout << char(alphabet + j);
			j++;
		}

		k = i - 1;
		while (k >= 0)
		{
			cout << char(alphabet + k);
			k--;
		}
		cout << "\n";
		i++;
	}
}
