C++ Coding Notes

1. constructor overloading

2. Class繼承後的constructor 跟 destructor(刪除順序)

3. difference between overloading & overriding

4. Type casting
     http://hscripts.com/tutorials/cpp/type-casting.php

5. for(...; ....; ++x) 比 for(...; ....; x++) 有效率

6. scanf, fscanf in C language do not accept(recognize) string type(C++)

7.for 迴圈時 pointer *(A+x) 比 A[x] 有效率

8. {intx....} 大括弧可以限制變數生命週期

9. new 空間完都要檢查，在記憶體不足的電腦裡容易抓不到空間
int* p = new int[1000];  if(!p){printf"no memory!!"}

10. register 關鍵字用來讓變數存放於 CPU register ，加速存取記憶體。


Problem:
1. what is a virtual funciton? (seems to be used in overriding)
2. what is the difference between define funciton & inline function?
3. how to write an exception handler?
