Definition

, Per esempio:

natare a [3] [4], b [5], [10];

Definitio A est ordinata 3*4 (3 lines 4 columns), B est ordinata 5*10 (5 lines 10 columns). Nota quod

innatare [3, 4], b [5, 10];

haud facile est comprehendere, programmata linguae C eiusque eventus operationis;

 #include int main (int Argc, const char * argv []) {int Array [3] [5] = {0}; // Define a two-dimensional array (3 rows 5 columns) int Temp = 0 ; // Set a temporary integer variable to assign a value for the array for (int A = 0; a  operatio effectus est (facile visum; consummatio in mensam);

ordinata [0] [0] = 1	array [0] [1] = 2 < / p>	ordinata [0] [2] = 3	ordinata [0] [3] = 4	ordinata [0] [4] = 5
ordinata [1] [0] = 6	ordinata [1] [1] = 7	Ordinare [1] [2] = 8	ordinata [1] [3] = 9	ordinata [1] [4] = 10
ordinata [2] [1] = 12	ordinata [2] [2] = 13	array [2] [3] = 14 < / p>	ordinata [2] [4] = 15

overview

Duo dimensiva ordinata a [m] [n], hoc est M linea, N columna duo dimensiva ordinata. Pone [P] [q] pro primo elemento A, id est, duarum dimensivarum ordinatarum Subscriptio a P ad M + P, columna subscripta ab q ad n + q, press "Row prior ordo" Repone Cum est. reposita, oratio elementi a[i] [p] computata est;

LOC (a [i] [J]) = LOC (a [p] [q]) + (i - p) * n + (j - q)) * t

Cum actarum per "columnam ordinis prioritatem", oratio computata est:

LOC (a [i] [j]) = LOC (a [p] [q]) + ((j - q) * m + (i - p)) * t
