C++ 打印 1 和 0 列图案程序

编写一个 C++ 程序，使用 For 循环和示例打印 1 和 0 列图案。在此 C++ 列图案示例中，我们在嵌套的 for 循环中使用 if-else 语句来检查列号是偶数还是奇数。如果是奇数列，则打印 0，如果是偶数列，则打印 1。 

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows, columns;
     
    cout << "\nPlease Enter the Number of Rows = ";
    cin >> rows;
    
    cout << "\nPlease Enter the Number of Columns = ";
    cin >> columns;
     
    cout << "\n---1 and 0 Column Pattern-----\n";
    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j <= columns; j++)
		{
			if(j % 2 != 0)
			{
				cout << "0";
			}
			else
			{
				cout << "1";
			}       	
        }
        cout << "\n";
    }
		
 	return 0;
}

使用 While 循环打印 0 和 1 列图案的 C++ 程序

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows, columns;
     
    cout << "\nPlease Enter the Number of Rows = ";
    cin >> rows;
    
    cout << "\nPlease Enter the Number of Columns = ";
    cin >> columns;
     
    cout << "\n---1 and 0 Column Pattern-----\n";
    i = 1; 
    while(i <= rows)
    {
    	j = 1; 
    	while(j <= columns)
		{
			if(j % 2 != 0)
			{
				cout << "0";
			}
			else
			{
				cout << "1";
			}   
			j++;    	
        }
        cout << "\n";
        i++;
    }
		
 	return 0;
}

Please Enter the Number of Rows = 8

Please Enter the Number of Columns = 13

---1 and 0 Column Pattern-----

0101010101010
0101010101010
0101010101010

在此 C++ 代码打印 1 和 0 列图案中，如果列是奇数列，则打印 1，如果列是偶数列，则打印 0。 

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows, columns;
     
    cout << "\nPlease Enter the Number of Rows = ";
    cin >> rows;
    
    cout << "\nPlease Enter the Number of Columns = ";
    cin >> columns;
     
    cout << "\n---1 and 0 Column Pattern-----\n";
    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j <= columns; j++)
		{
			if(j % 2 != 0)
			{
				cout << "1";
			}
			else
			{
				cout << "0";
			}       	
        }
        cout << "\n";
    }
		
 	return 0;
}

Please Enter the Number of Rows = 7

Please Enter the Number of Columns = 15

---1 and 0 Column Pattern-----
101010101010101
101010101010101
101010101010101
101010101010101
101010101010101
101010101010101
101010101010101

在此 C++ 1 和 0 列图案示例中，我们在嵌套的 for 循环内直接打印 j % 2 的结果。

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows, columns;
     
    cout << "\nPlease Enter the Number of Rows = ";
    cin >> rows;
    
    cout << "\nPlease Enter the Number of Columns = ";
    cin >> columns;
     
    cout << "\n---1 and 0 Column Pattern-----\n";
    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j <= columns; j++)
		{
			cout << j % 2;    	
        }
        cout << "\n";
    }
		
 	return 0;
}

Please Enter the Number of Rows = 11

Please Enter the Number of Columns = 25
