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.

Printing pattern of 0's and 1's

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.

C# code for printing pattern of 0's and 1's

//include the namespace
using System;

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
