Better to get rid of all those pesky if() statements and just use
one return (disclaimer: not compiled):

    string
    BinaryString( const int N ){
        return
             N == 0  ?  "0"
          :  N == 1  ?  "1"
          :  BinaryString( N *1u /2 ) + BinaryString( N *1u %2 );
    }

(Note:  the 1u factors in the last line are there to avoid a
nasty bug when N is negative.)
