Accepted Answer

⚹ For question 1, I will choose the programming language Elixir ⚹ ‖ ▪ ⋮ Description: Elixir is a functional, concurrent, general-purpose programming language that runs on the Erlang virtual machine (BEAM). It is designed for building scalable and maintainable applications. ‖ ‖ ▪ ⋮ Application: Elixir is best used for developing distributed, fault-tolerant systems, such as web applications and telecommunications systems. ‖ ‖ ▪ ⋮ Inventor and Date: Elixir was created by José Valim in 2011. ‖ ‖ ▪ ⋮ Compilation or Interpretation: Elixir is a compiled language; its code is compiled to bytecode for the Erlang virtual machine. ‖ ⚹ For question 2, the steps in compilation are: ⚹ ‖ ▪ ⋮ Preprocessing: The preprocessor handles directives like #include and #define, expanding them where necessary. ‖ ‖ ▪ ⋮ Lexical Analysis: The source code is broken down into tokens. ‖ ‖ ▪ ⋮ Syntax Analysis: Tokens are organized into a parse tree according to the grammar of the language. ‖ ‖ ▪ ⋮ Semantic Analysis: The parse tree is checked for semantic consistency with the language's rules. ‖ ‖ ▪ ⋮ Intermediate Code Generation: The compiler generates an intermediate representation of the source code. ‖ ‖ ▪ ⋮ Optimization: The intermediate code is optimized for performance improvements. ‖ ‖ ▪ ⋮ Code Generation: The optimized intermediate code is translated into the target machine language. ‖ ‖ ▪ ⋮ Linking: The generated machine code is linked with other code libraries to create the final executable. ‖ ⚹ For question 3, the purpose of a symbol table is: ⚹ ‖ ▪ ⋮ Storage: It stores information about identifiers, such as variables, functions, classes, and objects. ‖ ‖ ▪ ⋮ Scope Resolution: It helps in managing the scope of identifiers to determine where they are accessible in the code. ‖ ‖ ▪ ⋮ Type Checking: It assists in type checking by keeping track of the data types of identifiers. ‖ ⚹ For question 4, an interpreter does the following: ⚹ ‖ ▪ ⋮ Translation: It translates high-level programming language code into machine code. ‖ ‖ ▪ ⋮ Execution: It executes the program directly, without producing an intermediate compiled program. ‖ ‖ ▪ ⋮ Runtime Evaluation: It evaluates expressions and statements in the program at runtime. ‖ ⚹ For question 5, five languages that are descendants of C are: ⚹ ‖ ▪ ⋮ C++: An extension of C with object-oriented features. ‖ ‖ ▪ ⋮ Objective-C: A reflective, object-oriented language that adds Smalltalk-style messaging to C. ‖ ‖ ▪ ⋮ C#: A language developed by Microsoft that combines principles from C and C++. ‖ ‖ ▪ ⋮ Java: A language that was influenced by C++ but designed for cross-platform compatibility. ‖ ‖ ▪ ⋮ JavaScript: Although not directly descended from C, it has C-like syntax and was influenced by C. ‖
