C# program to print pattern of 0's and 1's

This C# program is used to print 0's and 1's in a pattern, here I am using two loops (nested loop) and one counter variable to print the pattern, explanation and output is in the article.

In this C# program, we are printing the following pattern of 0's and 1's.

1
01
010
1010

In this following solution, we will learn how to print the following of 0's and 1's.

Looking at the pattern shows that the 0 comes at odd position while 1 comes at even, when we start indexing from 0.

So for this we can use the modular logic. We have taken a count variable c which is the position; if the c is at odd index then 0 will be printed otherwise 1 will be printed.

In this we are using 2 for loops one for the row and other for the columns.

Consider the program:

using System;  //include the namespace
namespace program
{
	class ab
	{
		static void Main(String[] args)
		{
			int i,j,c=0;
			
			for(i=0;i<4;i++)  //loop for row
			{
				for(j=0;j<=i;j++)  //loop for column
				{
					c++;  //increment in count variable
					if(c%2==0)  
						Console.Write(0);
					else
						Console.Write(1);
				}
				Console.WriteLine();  //for new line
			}
		}
	}
}

Output

1
01
010
1010
