编写一个C++程序,使用for循环打印空心倒置的右三角星形图案。
#include using namespace std;
int main() { int i, j, rows;
cout << "Enter Hollow Inverted Right Triangle Star pattern Rows = ";
cin >> rows;
cout << "Hollow Inverted Right Angled Triangle Star Pattern\\n";
for(i = rows; i > 0; i--)
{
for(j = 1; j <= i; j++)
{
if(j == 1 || j == i || i == 1 || i == rows)
{
cout << "\*";
}
else
{
cout << " ";
}
}
cout << "\\n";
}
return 0;
}
这个C++模式的例子使用while循环打印给定字符的空心倒直角三角形。
#include using namespace std;
int main() { int i, j, rows; char ch;
cout << "Enter Rows = ";
cin >> rows;
cout << "Enter Symbol = ";
cin >> ch;
i = rows;
while( i > 0)
{
j = 1;
while( j <= i)
{
if(j == 1 || j == i || i == 1 || i == rows)
{
cout << ch;
}
else
{
cout << " ";
}
j++;
}
cout << "\\n";
i--;
}
return 0;
Enter Rows = 15
Enter Symbol = $
