Pascal ABC is a learning system that allows schoolchildren and students to become familiar with the programming language of the same name. It was developed in 2002 by Russian scientists. The task of the developers was to create a programming environment that would meet the standards of our time and could easily teach students.
The interpreter is designed for 32-bit systems and contains methods for implementing some features. Moreover, the initial ones were considered unnecessary for training.
The compiler allows the use of simplified types of language constructs, which facilitates the transition from basic programs to modular and object-oriented.
Pascal ABC has become free software since version 3.0.
Features
The program has tips that are provided when writing code, autoformatting, a debugger, and form designer. The programming environment is designed for tasks of easy and medium complexity and for language learning.
The compiler is capable of executing code as fast as C # does, and a little slower than C ++, Delphi.
Thanks to the .NET platform, the software supports all the features of Microsoft.NET and its own library. You can safely use the latter in your programs, even relying on those created in another programming language.
Pascal ABC also has an online version, which has become widespread. It works without failures, the input-output process takes place over the network; programs are saved on the server.
Among many programmers there is an opinion that Pascal is a dead language, and stopping its use is a matter of time. This statement is based on the fact that schools use the old programming environment with reduced capabilities. This prevents students from appreciating all the functions of the language.
Training modules
Thanks to Microsoft.NET, Pascal ABC received a standard library, which has many classes that allow you to solve problems of varying complexity. That is why there is simply no need to develop our own modules, but there is certainly an opportunity to do this. As a rule, those that already exist thanks to programmers are aimed at better mastering the language.
In order to educate schoolchildren, the modules "Robot" and "Draftsman" are used. They have more than 200 examples that are subject to auto-verification. Thanks to the solution of these problems, a person can easily master the basic constructions of the Pascal language.
Modules on this list do not end there. There is a built-in electronic problem book, which is useful to those who study independently or want to repeat the material, to consolidate knowledge.
In order to create graphic elements in the Pascal ABC program, vector and raster graphics modules are used.
Differences
The programming environment has a form designer, thanks to which you can create a window application. Unlike other compilers, this one does not have a too voluminous and sophisticated interface, does not create many additional files. Interacting with one small program, Pascal ABC forms only one element on the disk.
The programming environment has a special shell that works with console tasks. The input and output of information is carried out precisely in it, designed in the form of a window. Among the "native" languages used by the program, there are Russian and English, which makes it convenient to use it.
Tasks
Tasks are written using the Pascal programming language. It is easy to learn, so the first program may well be very easy to use. The following lines are considered debut throughout the world:
- Begin.
- Writeln ('Hello World!').
- End.
The first and last lines are operator brackets in which the essence of the task should be located. The second - announces the output of the text in quotation marks. These are such easy examples. Pascal ABC has many similar programs in its puzzles that are easy and fun to learn from.
