Syntax & Semantics

Here we'll see about the Syntax and Semantics of MathX language

In the Introduction Section, we executed the following code:

!: Hello World Program in MathX Language.

main-para:-
println "Hello, World!".

Let us inspect the above code:

• Every Statement/Command written in MathX ends with a period"."

• Line starting with !: are not executed by the compiler. They are known as comments. These are used to document your code.

• Lines after the main-para:- header are executed.

• Every Program should end with a newline. Else, the compiler will raise a SyntaxError

With these inspections, you may now have a conclusion about how a program looks. Let's dive deep into it!

Comments

Comments are used to give documentation to your code. They are useful as they make code readable. Single-Line Comments are only available in MathX. For example:

!: This is not seen by compiler.

main-para:-
println "How are you?".

These can also be used to exclude a part of code to be executed temporarily.

println "Enter a no: ".
println "Dont execute".

println "Enter a no: ".
!: println "Dont execute".

This prevents the compiler from executing the 2nd line. meanwhile, you can debug(i.e., check errors) in your code. Don't forget to remove your comment after debugging.
