指標測試之函數中變數地址對齊情況

試代碼：

# include
"stdafx.h"
# include
<iostream>
# include
<Windows.h>

using
namespace std;

static
void DelaySeconds(int Time);

int _tmain(int argc, _TCHAR* argv[])
{
char       CharPointer[13]     = {NULL};
char       CharPointer1[13]    = {NULL};
char       CharPointer2[13]    = {NULL};
short
int  ShortIntPointer[13]
= {NULL};
int        IntPointer[13]      = {NULL};
long  int  LongIntPointer[13]  = {NULL};

cout<<"CharPointer    :"<<&CharPointer<<endl;
cout<<"CharPointer + 1:"<<CharPointer+1<<endl;
cout<<"CharPointer1   :"<<&CharPointer1<<endl;
cout<<"CharPointer2   :"<<&CharPointer2<<endl;

cout<<"ShortIntPointer    :"<<&ShortIntPointer<<endl;
cout<<"ShortIntPointer + 1:"<<ShortIntPointer+1<<endl;

cout<<"IntPointer        :"<<&IntPointer<<endl;
cout<<"IntPointer + 1    :"<<IntPointer+1<<endl;

cout<<"LongIntPointer     :"<<&LongIntPointer<<endl;
cout<<"LongIntPointer + 1 :"<<LongIntPointer+1<<endl;

DelaySeconds(60);

return
0;
}

void DelaySeconds(int Time)
{
    Sleep(Time*1000);
}
