C++ 程序打印倒置的直角三角形数字（逆序）

编写一个 C++ 程序，使用 for 循环打印逆序的倒置直角三角形数字。

#include<iostream>
using namespace std;

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

    cout << "Inverted Right Triangle of Numbers in Reverse Order Pattern\n"; 

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

这个 C++ 示例 使用 while 循环显示了逆序打印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 Nums in Reverse Rows = ";
    cin >> rows;

    cout << "Inverted Right Triangle of Numbers in Reverse Order Pattern\n"; 
    i = 1;
    
    while( i <= rows)
    {
        j = rows;
    	while( j >= i)
		{
            cout << j << " ";
            j--;
        }
        cout << "\n";
        i++;
    }		
 	return 0;
}

Enter Inverted Right Triangle of Nums in Reverse Rows = 13
