有如下程序:includeusing namespace std;class Amount{int amount;public:Amount(int

有如下程序: #include<iostream> using namespace std; class Amount{ int amount; public: Amount(int n=0):amount(n){ } int getAmount( )const{return amount;} Amount&operator+=(Amount A) { amount+=a.amount; return; } }; int main( ){ Amount x(3),y(7); x+=y: cout<<x.getAmount( )<<endl; return 0; } 已知程序的运行结果是10,则下画线处缺失的表达式是

A.*this

B.this

C.&amount

D.amount
