typedef struct tagVector { float x;
                           float y;
                           float z; } Vector, *pVector;
此時我們多了兩個新的自定型態：Vector, pVector (指標型態);
所以，
Vector v1, v2, v3; 等同於    struct tagVector v1, v2, v3;  等同於    struct { float x;
         float y;
         float z; } v1, v2, v3;
//===============================================    pVector pv1, pv2; 等同於 (不必再加*號)    struct tagVector *pv1, *pv2; 等同於    struct { float x;
         float y;
         float z; } *pv1, *pv2;    一樣是方便的喔！

引言: bigdogchina 您好： 其實C/C 的structure也是可以這樣做的喔！

struct TOneRecord{
  AnsiString Name;
  DWORD  Age;
};  // (注意要有分號)    // in C
struc TOneRecord  OneRecord,SecondRecord,ThreeRecord;    // in C  
struc TOneRecord  OneRecord,SecondRecord,ThreeRecord;
or
TOneRecord  OneRecord,SecondRecord,ThreeRecord;

至於將變數寫在定義後面，主要可能是該結構宣告只用一次，乾脆將定義與變數一塊寫出，或者是更進一步的要建立一個新的型態，如下：

typedef struct tagVector { float x;
                           float y;
                           float z; } Vector, *pVector;    此時我們多了兩個新的自定型態：Vector, pVector (指標型態);
所以，
Vector v1, v2, v3; 等同於    struct tagVector v1, v2, v3;  等同於    struct { float x;
         float y;
         float z; } v1, v2, v3;
//===============================================    pVector pv1, pv2; 等同於 (不必再加*號)    struct tagVector *pv1, *pv2; 等同於    struct { float x;
         float y;
         float z; } *pv1, *pv2;    一樣是方便的喔！
