how can i perform bitwise AND operation of two binary numbers?

[aurora]

how can i perform bitwise and operation on two binary numbers?
Ex: A-->1101
B-->1011
Then A AND B-->1001

I tried like this but getting compilation error saying that error: request for member 'operator&' in 'bin_celVal', which is of non-class type 'int'

what changes i have to do here?

int bin_celVal=BinVal(PrCell);
                                    int bin_Val=BinVal(Val);
                            int ANDresult= bin_celVal.operator &(bin_Val);
                            cout<<"RESULT:"<<ANDresult<<endl;

int bin_celVal=BinVal(PrCell);
                                    int bin_Val=BinVal(Val);
                            int ANDresult= bin_celVal.operator &(bin_Val);
                            cout<<"RESULT:"<<ANDresult<<endl;
