Turing programming language is named after the mathematician and computer scientist, Alan Turing. It is a high-level programming language and a dialect of Pascal that was designed for education purposes. It is used for teaching fundamental programming concepts such as data structures, control structures, functions, recursion, and file input/output. In this guide, we will take a look at Turing programming language, how to write it with an example, and what are the best applications for it.

How to write Turing Programming Language

Turing programming language uses a syntax similar to Pascal. The basic structure of a Turing program includes a header, a variable declaration section, and the main body of the program.

The header section is where you can specify the program name, author, and any other relevant information. The variable declaration section is where you define the variables you will use in the program. In Turing, you do not need to specify the data type of the variable, as the language has dynamic typing. You can simply assign a value to the variable and the language will determine the data type.

Here's an example of a Turing program that calculates the factorial of a number:

```
%Program to calculate the factorial of a number
%Author: John Doe
var
  num : int
  fact : int := 1
  i : int
begin
  put "Enter a number: "
  get num
  
  for i : 1 .. num
    fact := fact * i
  end for
  
  put "Factorial of " .. num .. " is " .. fact
end
```

In this program, we declare three variables: num, fact, and i. We then prompt the user to enter a number and store it in the num variable. We then use a for loop to calculate the factorial of the number and store it in the fact variable. Finally, we output the result to the console.

Best Applications of Turing Programming Language

Turing programming language is mainly used for teaching programming concepts and is not widely used in industry. However, it can be used for small projects or prototypes. Its simplicity and easy-to-understand syntax make it a great language for beginners to learn.

Turing programming language is also used in various academic institutions and schools to teach programming concepts to students. It is used as an introductory language to teach programming concepts, and once the students have a solid understanding of the concepts, they can move on to more complex languages.

In conclusion, Turing programming language is a great language for beginners to learn programming concepts. It has a simple syntax and can be used to create small projects or prototypes. It is mainly used in academic institutions and schools to teach programming concepts.
