salam sifu..

macam mana nk faham array yg tiga demensi ni..?

leh pecah kepala ni..

ade contoh yg paling simple tk..?
 
array 2 dimension.

int array[2][3];

array[0][0]=1;
array[0][1]=2;
array[0][2]=3;
array[1][0]=4;
array[1][1]=5;
array[1][2]=6;
 
Kat bawah ni contoh mudah untuk 2d array...

Code: 
Index | 0  | 1  | 2  | 3  | 4  |
------+----+----+----+----+----|
   0  | 00 | 10 | 20 | 30 | 40 |
------+----+----+----+----+----|
   1  | 01 | 11 | 21 | 31 | 41 |
------+----+----+----+----+----|
   2  | 02 | 12 | 22 | 32 | 42 |
------+----+----+----+----+----|
   3  | 03 | 13 | 23 | 33 | 43 |
------+----+----+----+----+----|
   4  | 04 | 14 | 24 | 34 | 44 |
-------------------------------+

Contoh nilai array mengikut index tertentu.
Array[0][0] = 00
Array[2][1] = 21
Array[4][4] = 44
Array[2][3] = 23

Kalau dalam bidang robotik, siap pakai 3D array untuk menggambarkan x,y dan z koordinat... Kalau EA, 2D dah kira habis canggih... Selalunya 1 dimensi jer... Indi cuma 1D je. Itu pun kalau pakai dia punya buffer...

Aku rekomen, mahirkan yang basic EA dulu... Array ni perlu kalau nak buat indi... Kalau dalam EA, selalunya kita guna kalau nak main multiple pair guna satu chart... Itu pun tak wajib... tak pakai array pun tak apa...

Kita guna array untuk ringkaskan coding, tapi bukan untuk simplifykan... Malah ia akan jadi lebih komplikated... Kena lebih peka, sebab kita lebih terdedah kepada programming glitch disebabkan loop dalam loop atau omputih kata nested loop...

Sorry bro,
Tak berapa minat nak kaji strategi atau kaji indi untuk diEAkan kat sini... Cuma minat nak citer pasal coding EA secara asas bagi sesiapa yang berminat nak belajar...

Tengok code yang dipecahkan lagi la tak minat...
 
bleh try guna array plak. nampaknya yg terbaik masukkan arrow cam sifu cadangkan. tapi takpa cuba cara lain plak. tq suma atas idea. selamat hari raya. moga persahabatan berkekalan
 
sory..aku silap pasal currency strengh ni..

bila aku ingat pair paling kuat(teratas) lawan pair paling lemah(terbawah)...mesti menang...aku silap...

rupanye..
