How can I write a two-dimensional array of binary data in Pascal?

  • It would be nice) I created an array of bin in pascal: array [1..2] of byte = ((0001), (0110)); The program recognizes its elements as 1 and 110, but I would like it to see exactly binary values. And I also have a question on two-dimensional arrays, maybe to create a chat? - JohnS

Binary data can be stored in different forms.

For example, in the form of an array of Boolean elements (1 element = 1 bit).

arr: array of array of Bool;

You can store as ordinary Integer and access them by masks to select specific bits (1 Integer = 32 bits).

 arr: array of array of Integer;

And even as a string of text (1 character = 1 bit).

 arr: array of array of String;
