Different types of variables cannot be grouped into an array. For this purpose, see records.
The declaration works similar to that for simple types, but you need to add the number of elements & basic type.
The simplest way is as follows - it defines a so-called static array:
program ... var variablename: array [startindex..endindex] of type; begin ...
type simple_integer_array = array [1..10] of integer; var Numbers: simple_integer_array;
More complex example:
type more_complex_array = array [0..5,1..3] of extended; var specialmatrix: more_complex_array;
Arrays reflect the mathematical concept of
- vectors (one-dimensional array) and
- matrices (two-dimensional array)
multidimensional array are supported such as [x..y,z..t] and so on.
To call a variable you have to put the name of the array and the position
a[1..3] and you can use it as a simple variable, but if you want to use parameters you MUST use a structure because else it will cause errors or bugs... (I do not understand, what is meant here).
If it is not possible to know the number of elements at the time of the program compilation, the dynamic array type can be used.
