C++ 打印连续字母组成的直角三角形图案程序

使用 for 循环编写一个 C++ 程序，打印连续字母组成的直角三角形图案。

#include<iostream>
using namespace std;

int main()
{
	int rows;

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

	cout << "Right Triangle of Consecutive Alphabets Pattern\n";
	int alphabet = 65;

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

使用 while 循环打印连续字母组成的直角三角形图案的 C++ 程序。

#include<iostream>
using namespace std;

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

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

	cout << "Right Triangle of Consecutive Alphabets Pattern\n";
	alphabet = 65;

	i = 0;

	while (i <= rows - 1)
	{
		j = 0;

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

Enter Right Triangle of Consecutive Alphabets Rows = 9

G H I J 
K L M N O 
P Q R S T U 
V W X Y Z [ \ 
] ^ _ ` a b c d 
e f g h i j k l m 

此 C++ 示例 使用 do while 循环在每一列中显示连续字母组成的直角三角形图案。

#include<iostream>
using namespace std;

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

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

	cout << "Right Triangle of Consecutive Alphabets Pattern\n";
	alphabet = 65;

	i = 0;

	do
	{
		j = 0;

		do
		{
			cout << char(alphabet++) << " ";

		} while (++j <= i);

		cout << "\n";

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

Enter Right Triangle of Consecutive Alphabets Rows = 10
