C language ---- multi-dimensional array

C language ---- multi-dimensional array
I. Definition:

When there are more than two array subscripts, the array is called a multi-dimensional array. (Multidimensional arrays are nested with multiple one-dimensional arrays .)

2. 3D array traversal:

For (int I = 0; I <layers; I ++) {for (int j = 0; j <number of rows; j ++) {for (int k = 0; k <Number of columns; k ++) {a [I] [j] [k] = xxx ;}}}

3. Multi-dimensional array access

1. Multi-dimensional array access element: array name [subscript] [subscript] [subscript]
2. int number = a [0] [0] [0]
3. Memory occupied by multi-dimensional arrays = number of elements multiplied by the space occupied by a single element
