1. int p=1;
int q=-1;
int i=-p++-q;
printf(“%d \n”,i);
2. 似乎是这样的：
class CA
{
public:
int i;
virtual ff(){i = 1};
void print(){printf(“%d\n”),i};
}
class CB:public class CA
{
private:
int i;
public:
virtual ff(){i = 2};
//void print(){printf(“%d\n”),i};
}
class CC:public class CB
{
private:
int i;
public:
virtual ff(){i = 3};
//void print(){printf(“%d\n”),i};
}
int main()
{
CC * A = new CB();
A->ff();
A->print();
CC * B = (CC *)new CA();
B->ff();
B->print();
CC * C= (CC *)new CB();
C->ff();
C->print();
}
3. C++ 比c好的地方。（多选）
4. inline 函数的特点 (多选)
5. inline ＆ 宏的不同 （多选）
6. 什么叫做抽象
