[求助]关于类和结构体一些问题

类变量和结构体变量用“.”

类指针和结构体指针用“->”

例：
class Complex
{
public:
Complex(){}
Complex(int a, int b):_a(a), _b(b){}
void show()
{
cout << _a << "+" << _b << "i" << endl;
}
private:
int _a;
int _b;
};

int main()
{
Complex com1(2,3);
Complex* com2 = &com1;
com1.show();
com2->show();
return 0;
}

-> equal to *.

ex:

obj a;
a.fun();
obj *p;
p->fun();
(*p).fun();

all right!
