• Program

• #include <stdio.h>
   
  int main()
  {
   
      long binary1, binary2;
      int i = 0, remainder = 0, sum[20];
      scanf("%ld", &binary1);
       scanf("%ld", &binary2);
      while (binary1 != 0 || binary2 != 0)
      {
          sum[i++] =(binary1 % 10 + binary2 % 10 + remainder) % 2;
          remainder =(binary1 % 10 + binary2 % 10 + remainder) / 2;
          binary1 = binary1 / 10;
          binary2 = binary2 / 10;
      }
      if (remainder != 0)
          sum[i++] = remainder;
      --i;
      printf(" ");
      while (i >= 0)
          printf("%d", sum[i--]);
      return 0;
