1. What¡¯s overload function in C++

2. A. What¡¯s inline function in C++

B. When would you use inline function

C. Please write sample code.

3. Which of the following are legal For those usages that are illegal, explain why.

const int buf;

int cnt = 0;

const int sz = cnt;

cnt++; sz++;

4. Please point out the errors in the following C++ code. And why

switch ( ival )

{

case 1, 3, 5, 7, 9:

oddcnt++;

break;

case 2, 4, 6, 8, 10:

evencnt++;

break;

}

5. Given the following base and derived class definitions:

class Base

{

public:

foo ( int );

protected:

int _bar;

double _foo_bar;

};

class Derived: public Base

{

public:

foo ( string );

bool bar ( Base *pb );

void foobar ();

protected:

string _bar;

};

Identify what is wrong with each of the following code fragments and how each might be fixed:

(a) Derived d; d.foo ( 1024 );

(b) void Derived :: foobar () { _bar=1024; }

(c) bool Derived :: bar { Base *pb }

{ return _foo_bar = = pb->_foo_bar; }

6. A. Please list all the design patterns you known.

B. Please explain the pattern of ¡°Factory¡± and give an example if you can.

7. A. Please list all the sorting algorithms you known.

B. Please use pseudo code to describe the algorithm of ¡°Quick Sort¡±.

8. Please answer the following questions:

A. What¡¯s process scheduling and list all scheduling algorithms you known.

B. What¡¯s the ¡°Race Condition¡±

C. Please explain the diagram of process state change.
