Currently, I$\text{'}$m running a full$-$on Linux environment on WSL$,$or Windows Subsystem for Linux, with an Ubuntu distribution. My code editor of choice is Visual Studio Code, and I already set it up to work seamlessly on this setup.

Installation Process

Visual Studio Code:$$

I installed it using the $.$deb package. The following is the used command:

$$sudo dpkg $-$i code.deb

Compiler Tools $($Flex & Bison$)$

To be within the course requirement, I have installed Flex and Bison through the following commands:

$$sudo apt$-$get update

$$sudo apt$-$get install flex bison

Below is a screenshot demonstrating the successful installation of these tools.

THE ASK $**$

Provide a program in the target language of our compiler$/$interpreter that incorporates all elements of the language. It must include all of the following:

Integer $($Decimal and Hexadecimal$),$Real and Character literals

Every arithmetic operator: $+-*/\%^$~

Every relational operator: $=/=>>=<<=$

Every logical operator: &

A when statement$|$

An if statement

A switch statement

A fold statement

Multiple variable declarations

Multiple parameter declarations

In addition, your program should be written in a such a way that it tests the associativity and precedence of all operators. It should also include nested statements.

Also provide several sets of input $($values for the parameters$)$to the program, enough so that every line of code within the program is executed at least once. For each input supplied, provide the corresponding output.

Discussion questions are requiring code examples using the target language $.$

Test case example

$//$ Function with a lexical error

function main returns integer;

begin

$7*2$ $ $(2+4)$;

end;
