What is 2D arrays in Delphi

Answer 1

[AI-generated answer — Bot GPT 3.5]

In Delphi, a 2D array is a multi-dimensional array that has two dimensions or indexes. This means that it is an array of elements, where each element is also an array.

For example, a 2D array in Delphi can be declared and initialized as follows:

```Delphi
var
myArray: array[0..2, 0..2] of Integer;
begin
myArray[0, 0] := 1;
myArray[0, 1] := 2;
myArray[0, 2] := 3;
// Continue initializing the array as needed
end;
```

In this example, `myArray` is a 2D array with 3 rows and 3 columns, where each element is an Integer. To access a specific element in the array, you use two indexes - one for the row and one for the column.

2D arrays are useful for storing and manipulating data that has a grid-like structure, such as tables, matrices, or images. They provide a convenient way to organize and access elements in a two-dimensional layout.
