class derived{};
class derived2: public base, derived {};
which is true?
1) This is illegal
2) derived2 is derived public from base and private from derived
3) derived2 is derived public from base and public from derived
4) derived2 is derived public from base and protected from derived
class X{
public:
X& operator=(const X& rhs);
const X& operator+(const X&rhs) const;
const X& operator+(int m);
private:
int n;
};
int main(){
X a, b, c;
system("pause");
return 0;
}
which one is wrong?
a=c+5;
a=a=b+c;
(a=c+4)=b+2;
a=b+c;
b=a+1; |
