C++ 打印加星图案程序

用 for 循环编写一个 C++ 程序来打印加星图案。 

#include<iostream>
using namespace std;

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

    cout << "Plus Star Pattern\n"; 

    for(i = 1; i <= rows * 2 - 1; i++)
    {
        if(i != rows)
        {
            for(j = 1; j <= rows; j++)
            {
                if(j == rows)
                {
                    cout << "*";
                }
                cout << " ";
            }
        }
        else
        {
            for(k = 1; k <= rows * 2 - 1; k++)
            {
                cout << "*";
            }
        }
        cout << "\n";
    }	
 	return 0;
}

这个 C++ 示例使用 while 循环打印给定字符的加号图案。

#include<iostream>
using namespace std;

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

    cout << "Enter Symbol for Plus Star Pattern = ";
    cin >> ch;

    cout << "Plus Star Pattern\n"; 
 
    while(i <= rows * 2 - 1)
    {
        if(i != rows)
        {
            j = 1;
            while( j <= rows)
            {
                if(j == rows)
                {
                    cout << ch;
                }
                cout << " ";
                j++;
            }
        }
        else
        {
            k = 1;
            while( k <= rows * 2 - 1)
            {
                cout << ch;
                k++;
            }
        }
        cout << "\n";
        i++;
    }	
 	return 0;
}
