C++ 程序打印反向镜像的直角三角形星形图案

编写一个 C++ 程序，使用 for 循环打印反向镜像的直角三角形星形图案。

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows;
     
    cout << "Enter Reverse Mirrored Right Triangle Star Pattern Row = ";
    cin >> rows;

    cout << "Reverse Mirrored Right Angled Triangle Star Pattern\n"; 

    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j <= rows; j++)
		{
            if(j < i)
            {
                cout << " ";
            }
            else 
            {
                cout << "*";
            }        
        }
        cout << "\n";
    }		
 	return 0;
}

这个 C++ 示例 使用 while 循环以给定字符的相反顺序打印镜像的直角三角形图案。

#include<iostream>
using namespace std;

int main()
{
	int i = 1, j, rows;
    char ch;
     
    cout << "Enter Reverse Mirrored Right Triangle Star Pattern Row = ";
    cin >> rows;

    cout << "Enter Symbol for Reverse Mirrored Right Triangle Pattern = ";
    cin >> ch;

    cout << "Reverse Mirrored Right Angled Triangle Star Pattern\n"; 

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

    	while( j <= rows)
		{
            if(j < i)
            {
                cout << " ";
            }
            else 
            {
                cout << ch;
            } 
            j++;       
        }
        cout << "\n";
        i++;
    }		
 	return 0;
}

Enter Reverse Mirrored Right Triangle Star Pattern Row = 15
Enter Symbol for Reverse Mirrored Right Triangle Pattern = $
Reverse Mirrored Right Angled Triangle Star Pattern
