// it's caller's responsibility to delete the memory
char * conv_int_to_binary(int data)
{
    int size = sizeof(data)*8;
    char *binString = new char(size);

   for ( int i = 0; i > i)&1;
     }
  return binString;
}

Sharat Chandra · Answer

length = (int) (log (num)  +1) ;  // log to base 2

while (  (num/2) > 0)){
              rem=num%2;
              binary[length-i-1] = rem;
              num=num/2 ;
              i--;
}
