How to find the Sum of two Binary Numbers using C#?

To find the sum of two binary numbers, firstly set them.

val1 = 11110;
val2 = 11100;

Now call the displaySum() method, which created to display the sumL.

sum = displaySum(val1, val2);

We have set a new array in the method to display each bit of the binary number.

long[] sum = new long[30];

Now let us see the complete code to calculate the sum of binary numbers as shown in the code below −

Example

using System;
class Demo {
   public static void Main(string[] args) {
      long val1, val2, sum = 0;
      val1 = 11110;
      val2 = 11100;

      Console.WriteLine("Binary one: "+val1);
      Console.WriteLine("Binary two: "+val2);

      sum = displaySum(val1, val2);
      Console.WriteLine("Sum = {0}", sum);
   }

   static long displaySum (long val1, long val2) {
      long i = 0, rem = 0, res = 0;
      long[] sum = new long[30];

      while (val1 != 0 || val2 != 0) {
         sum[i++] =(val1 % 10 + val2 % 10 + rem) % 2;
         rem =(val1 % 10 + val2 % 10 + rem) / 2;
         val1 = val1 / 10;
         val2 = val2 / 10;
      }
      if (rem != 0)
      sum[i++] = rem;

      i = i-1;

      while (i >= 0)
      res = res * 10 + sum[i--];
      return res;
   }
}

Output

Binary one: 11110
Binary two: 11100
Sum = 111010
