第1题：
有如下程序: includeusing namespace std; class PARENT { public: PARENT() { cout 有如下程序：
include ＜iostream＞
using namespace std;
class PARENT
{
public:
PARENT() { cout ＜＜"PARENT"; }
};
class SON : public PARENT
{
public:
SON() {cout ＜＜ "SON"; }
};
int main()
{
SON son;
PARENT *p;
p = &son;
return 0;
}
执行上面程序的输出是______。
正确答案：PARENTSON
PARENTSON 解析：此题考查的是派生类的构造。主函数开始在定义SON类的对象son时，会先执行PARENT类的构造函数再执行SON类的构造函数，输出 “PAKENTSON”；接下来的语句定义PARENT和让指针p指向son对象，都并未创建任何对象，所以不会调用构造函数。故最终的输出结果是：PARENTSON。 -
第2题：
The ONS 15216 is a 32－channel system. The ONS 15216 OADMs are capable of adding and dropping one, two, or four channels. How are the OADMs provisioned to add and drop specific channels?()A. The ONS 15216 OADM can be provisioned to add/drop one, two, or four channels via Cisco Transport Manager (CTM).
B. The ONS 15216 OADM consists only of a four-channel module, and the number of ports utilized determines whether it is a one, two, or four channel OADM.
C. Three separate OADM modules are available for one, two, and four channels. The wavelengths to be dropped and added are programmable via Cisco Transport Manager (CTM).
D. The ONS 15216 OADM consists only of a single-channel module. Two-channel and four-channel support is available by stacking the single-channel module.
E. The ONS 15216 OADM is available in one, two, four channels. There are 32 single-channel OADM modules, 16 two-channel OADM modules, and 8 four-channel OADM modules.
