const int * pi 、int const * pi與int * const pi及其操作1 從const int i 說起 你知道我們申明一個變數時象這樣int i ;這個i是可能在它處重新變賦值的。如下:int i=0;//…i=20;//這裡重新賦值了不過有一天我的程式可能需要這樣一個變數(暫且稱它變數),在申明時就賦一個初始值。之後我的程式在其它任何處都不會再去重新對它賦值。那我又應該怎麼辦呢?用const 。//**************const int
一.環境: x86/WinXP/VC 6.0二.用例:int swap(int a, int b){ int v; v = a; a = b; b = v; return v;}void main(void){ int a = 7; int b = 10; int c = 0; c = swap(a,b); return;}三.分析:1: int swap(int a, int b)2: {00401020 push ebp00401021 mov
