Do you speak Object Pascal?

The Pascal language was designed to teach good programming practices, and its modern counterpart, the Object Pascal language, in use today, still holds true to some of the core tenets in terms of readability and clarity. The Object Pascal language in today’s Delphi is a high-level, modern, strongly typed compiled language that supports structured and object-oriented programming.

To solve a problem using a computer, you need to define a finite set of actions that operate on certain data – or in other words, to define an algorithm. An algorithm expressed in a programming language is a computer program and its actions are described as programming language instructions.

One or more actions that are performed on certain data can be encapsulated in Object Pascal language as a routine or a class. In most programming languages, routines are called functions. In Object Pascal, if a function does not return a value, it is called a procedure. Classes...
