C++ 程序打印空心镜像菱形星形图案

编写一个 C++ 程序，使用 for 循环打印空心镜像菱形星形图案。

#include<iostream>
using namespace std;

int main()
{
	int i, j, k, rows;
     
    cout << "Enter Hollow Mirrored Rhombus Star Pattern Row = ";
    cin >> rows;

    cout << "Hollow Mirrored Rhombus Star Pattern\n"; 

    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j < i; j++)
		{
            cout << " ";
        }
        for(k = 1; k <= rows; k++)
        {
            if (i == 1 || i == rows || k == 1 || k == rows)
            {
                cout << "* ";
            }
            else
            {
                cout << "  ";
            }         
        }
        cout << "\n";
    }		
 	return 0;
}

这个 C++ 示例使用 while 循环打印给定字符的空心镜像菱形图案。

#include<iostream>
using namespace std;

int main()
{
	int i = 1, j, k, rows;
    char ch;
     
    cout << "Enter Hollow Mirrored Rhombus Star Pattern Row = ";
    cin >> rows;

    cout << "Enter Symbol for Hollow Mirrored Rhombus Pattern = ";
    cin >> ch;

    cout << "Hollow Mirrored Rhombus Star Pattern\n"; 

    while(i <= rows)
    {
        j = 1; 
    	while(j < i)
		{
            cout << " ";
            j++;
        }
        k = 1; 
        while(k <= rows)
        {
            if (i == 1 || i == rows || k == 1 || k == rows)
            {
                cout << ch << " ";
            }
            else
            {
                cout << "  ";
            }   
            k++;      
        }
        cout << "\n";
        i++;
    }		
 	return 0;
}

Enter Hollow Mirrored Rhombus Star Pattern Row = 14
Enter Symbol for Hollow Mirrored Rhombus Pattern = %
Hollow Mirrored Rhombus Star Pattern
