西门子笔试归来

刚刚从西十二胜利大逃亡，呵呵，西门子的笔试也太bt了！什么都要考，</P>

Software Engineering Process ,UML/design patterns ,Java ,C /C++,Database,

Hardware,全E文的，看来西门子要“全才啊”！全球500强的要求也太高了吧，呵呵，看来自己也需要全面提高啊！

附：西门子笔试C＋＋编程题一道：

写出程序的output
＃i nclude <iostream.h>

class A {
private:
int num;
public:
A() {
cout<<"Default constructor"<< endl;
}
~A() {
cout<<"Desconstructor"<< endl;
cout<<num<<endl;
}
A(const A &a){
cout<<"Copy constructor"<<endl;
}
void operator=(const A &a) {
cout<<"Overload operator"<<endl;
}
void SetNum(int n) {
num=n;
}
};

void main()
{
A a1;
A a2(a1);
A a3=a1;
A &a4=a1;
um(1);
um(2);
um(3);
um(4);
}
