C++ 程序打印降序数字的倒置直角三角形

编写一个 C++ 程序，使用 for 循环打印降序数字的倒置直角三角形模式。

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows;
     
    cout << "Enter Inverted Right Triangle of Desc Numbers Rows = ";
    cin >> rows;

    cout << "Inverted Right Triangle of Numbers in Descending Ord Pattern\n";  

    for(i = rows; i >= 1; i--)
    {
    	for(j = i; j >= 1; j--)
		{
            cout << j << " ";
        }
        cout << "\n";
    }		
 	return 0;
}

这个 C++ 示例 使用 while 循环打印降序数字的倒置直角三角形。

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows;
     
    cout << "Enter Inverted Right Triangle of Desc Numbers Rows = ";
    cin >> rows;

    cout << "Inverted Right Triangle of Numbers in Descending Ord Pattern\n";  
    i = rows;

    while( i >= 1)
    {
        j = i;
    	while (j >= 1)
		{
            cout << j << " ";
            j--;
        }
        cout << "\n";
        i--;
    }		
 	return 0;
}

Enter Inverted Right Triangle of Desc Numbers Rows = 15
