The Object Pascal language has been designed for teaching good programming practices. It is a high-level, modern, and strongly typed compiled language that supports structured and object-oriented programming.
In order 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 performed on certain data can be encapsulated in the Object Pascal language as a routine or a class. In Object Pascal, routines are called functions. If a function does not return a value, it is called a procedure. Classes are the corner stones of object-oriented programming, which is the most important approach to building apps...
