1. Multidimensional Arrays

2. Multidimensional Arrays
Sometimes, it is useful to have an array with more than one index.
The following syntax declares an array with two indexes (the first from 0 to 29, the second from 0 to 99):
char page[30][100];
The elements of this array all have two indexes:
page[0][0]
page[15][32]
page[29][99]

3. Multidimensional Arrays
The most common number of indexes for a multidimensional array is 2.
Think of it as the first index giving the row and the second the column:
page[0][0] page[0][1] ... page[0][99]
page[1][0] page[1][1] ... page[1][99]
page[2][0] page[2][1] ... page[2][99]
...
page[29][0] page[29][1] ... page[29][99]

4. Multidimensional Arrays as Parameters
Recall that when using a one-dimensional array as a function parameter, the brackets are empty:
void print_array(int a[], int elements);
When using a multidimensional array as a parameter, the size of every dimension after the first must be given!
Generally there will also be a parameter to represent the size of the first dimension.
Example: void get_page(char p[][100], int size_1);
