Here are a few examples of array declaration:
var
weekdays : array[1..7] of byte;
samples : array[50] of word;
begin
// Now we can access elements of array variables, for example:
samples[0] := 1;
if samples[37] = 0 then ...
Constant Arrays
Constant array is initialized by assigning it a comma-delimited sequence of values within parentheses. For example:
// Declare a constant array which holds number of days in each month:
const MONTHS : array[1..12] of byte = (31,28,31,30,31,30,31,31,30,31,30,31);
The number of assigned values must not exceed the specied length. The opposite is possible, when the trailing
“excess” elements are assigned zeroes.
For more information on arrays of char, refer to Strings.
Multi-dimensional Arrays
Multidimensional arrays are constructed by declaring arrays of array type. These arrays are stored in memory in such
way that the right most subscript changes fastest, i.e. arrays are stored “in rows”. Here is a sample 2-dimensional
array:
m : array[5] of array[10] of byte; // 2-dimensional array of size 5x10
A variable m is an array of 5 elements, which in turn are arrays of 10 byte each. Thus, we have a matrix of 5x10 elements
where the rst element is m[0][0] and last one is m[4][9]. The rst element of the 4th row would be m[3][0].
