感謝Q大的解惑, 我寫得不夠清楚
目前的用法還是不合適
需要的矩陣是
const unsigned int uArray01A[17][15] = { ... };
const unsigned int uArray01B[17][15] = { ... };
const unsigned int uArray01C[17][15] = { ... };
const unsigned int uArray01D[17][15] = { ... };
const unsigned int uArray02A[19][17] = { ... };
const unsigned int uArray02B[19][17] = { ... };
const unsigned int uArray02C[19][17] = { ... };
const unsigned int uArray02D[19][17] = { ... };
const unsigned int uArray03A[21][19] = { ... };
const unsigned int uArray03B[21][19] = { ... };
const unsigned int uArray03C[21][19] = { ... };
const unsigned int uArray03D[21][19] = { ... };
const unsigned int uArray04A[23][21] = { ... };
const unsigned int uArray04B[23][21] = { ... };
const unsigned int uArray04C[23][21] = { ... };
const unsigned int uArray04D[23][21] = { ... };
const unsigned int uArray05A[25][23] = { ... };
const unsigned int uArray05B[25][23] = { ... };
const unsigned int uArray05C[25][23] = { ... };
const unsigned int uArray05D[25][23] = { ... };
矩陣大小是不固定的, 不過都是二維
但是想要用索引的方式
Ptr[index] = ....
藉由 Ptr[index] index=0; index++; 的方式
分別將每個 uArray[][]的 address取出
然後再將每個 uArray[][] 的內容
copy到一個共用的全域矩陣 g_uGobalArray[i][j];
實際的對每個矩陣元素的存取再由 g_uGobalArray[i][j]來存取
不知道有沒有大大可以幫忙解惑的
非常感謝!
※ 引述《ULISS (查無此人)》之銘言：
: 小弟想做個二維陣列的資料庫
: 但是在存取上面似乎有點棘手
: 想請教版上諸為高手解惑
: 謝謝!

: 編譯不過....orz
: 本來是想要用三維去做的
: 一組有四個二維陣列
: 然後假設有四組
: 但是每次是想要可以任意指定哪一組
: 也要決定哪一組的哪一個二維陣列的指標出來
: 請高手指點一下指標的用法....
: 謝謝!
: 感激不盡!
