C++ 打印数字倒直角三角形的程序

编写一个 C++ 程序，使用 for 循环打印数字倒直角三角形。

#include<iostream>
using namespace std;

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

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

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

这个 C++ 示例使用 while 循环打印倒序的数字在直角三角形模式中。

#include<iostream>
using namespace std;

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

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

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

Enter Right Triangle Numbers in Reverse Row = 17
