Question

How to generate binary numbers from 1 to N in C#

Answer 1

using System;

class Program
{
    static int LEN = 100;
    static void printBinaryNumber(int n) {
        int[] binary = new int[LEN];
        int i = 0;
           
        while (n > 0) {
            binary[i] = n % 2;
            n = n / 2;
            i++;
        }
        for (int j = i - 1; j >= 0; j--)
            Console.Write(binary[j]);
        Console.WriteLine();
    }
    static void generateBinaryNumbers(int n) {
        for (int i = 1; i <= n; i++) {
            printBinaryNumber(i);
        }
    }
    static void Main() {
        int N = 15;
  
        generateBinaryNumbers(N);
    }
}
