value=rhs.value;
return*this;
}
第4题:

第5题:
有如下程序: #include<iostream> using namespace std; int i=1; class Fun { public: static int i; int value(){return i-1;} int value()const{return i+1;} }; int Fun::i=2; int main() { int i=3; Fun fun 1; const Fun fun2; ______ return 0; } 若程序的输出结果是: 123 则程序中横线处的语句是( )。
A.cout<<fun1.value()<<Fun::i<<fun2.value();
B.cout<<Fun::i<<fun1.value()<<fun2.value();
C.count<<fun.value()<<fun2.value()<<Fun::i;
D.cout<<fun2.value()<<Fun::i<<fun1.value();
