C++程序打印降序数的倒置直角三角形

编写一个C++程序，使用for循环来打印降序数的倒右三角形图案。

#include 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++例子使用while循环打印降序数字的倒右三角形。

#include 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
