C++ 打印矩形星形图案程序

编写一个 C++ 程序来打印矩形星形图案，并附带一个示例。在此 C++ 矩形星形图案中，我们在 for 循环中使用了 if 语句。它有助于为矩形边框打印给定的字符或 '*'，为所有剩余位置打印空格。我们可以称之为“空心”矩形星形。

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows, columns;
	char ch;
	
	cout << "\nPlease Enter the Total Number of Rectangle Rows    =  ";
	cin >> rows;
	
	cout << "\nPlease Enter the Total Number of Rectangle Columns =  ";
	cin >> columns;
	
	cout << "\nPlease Enter Any Symbol to Print  =  ";
	cin >> ch;	
		
	cout << "\n-----Rectangle Pattern-----\n";
	for(i = 1; i <= rows; i++)
    {
        for(j = 1; j <= columns; j++)
		{
			if(i == 1 || i == rows || j == 1 || j == columns)
			{
				cout << ch;
			}
			else
			{
				cout << " ";
			}          
        }
        cout << "\n";
    }
 	return 0;
}

C++ 打印矩形星形图案示例 2

在此 C++ 示例中，我们删除了 If 语句，以打印一个完整的星形矩形。

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows, columns;
	char ch;
	
	cout << "\nPlease Enter the Total Number of Rectangle Rows    =  ";
	cin >> rows;
	
	cout << "\nPlease Enter the Total Number of Rectangle Columns =  ";
	cin >> columns;
	
	cout << "\nPlease Enter Any Symbol to Print  =  ";
	cin >> ch;	
		
	cout << "\n-----Rectangle Pattern-----\n";
	for(i = 0; i < rows; i++)
    {
        for(j = 0; j < columns; j++)
		{
           cout << ch;
        }
        cout << "\n";
	}
 	return 0;
}

Please Enter the Total Number of Rectangle Rows    =  8

Please Enter the Total Number of Rectangle Columns =  20

Please Enter Any Symbol to Print  =  $

使用 While 循环的 C++ 打印矩形星形图案程序

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows, columns;
	char ch;
	
	cout << "\nPlease Enter the Total Number of Rectangle Rows    =  ";
	cin >> rows;
	
	cout << "\nPlease Enter the Total Number of Rectangle Columns =  ";
	cin >> columns;
	
	cout << "\nPlease Enter Any Symbol to Print  =  ";
	cin >> ch;	
		
	cout << "\n-----Rectangle Pattern-----\n";
	i = 0; 
	while(i < rows)
    {
    	j = 0; 
        while(j < columns)
		{
           cout << ch;
           j++;
        }
        cout << "\n";
        i++;
	}
 	return 0;
}

Please Enter the Total Number of Rectangle Rows    =  10

Please Enter the Total Number of Rectangle Columns =  22

Please Enter Any Symbol to Print  =  @
