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.
