This week, our focus will be on crafting comprehensive programs in the target language of our compiler$/$interpreter$.$ It's time to put into practice all that we've learned thus far. Your task is to create a program that incorporates every element of the language we've been studying. This includes:

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

Moreover, ensure that your program is structured in such a way that it thoroughly tests the associativity and precedence of all operators. Additionally, include nested statements to demonstrate the full capabilities of the language.

As part of your submission, provide several sets of inputs to your program, ensuring that every line of code within it is executed at least once. For each input provided, document the corresponding output.
