The primary tool for proving properties about programs and language systems. The PCF (Programming Computable Functions) Language:
In an era where software safety is critical (from self-driving cars to blockchain), the ability to formally reason about code is a high-value skill. Compiler Design:
-- Type.hs data Type = TV String | TCon String [Type] deriving (Show, Eq) 15312 foundations of programming languages
Recognizing the boundary between static and dynamic behaviors allows you to exploit compiler errors to eliminate runtime vulnerabilities.
– Describe how a program executes step-by-step on an abstract machine. Example: “To evaluate x + 3 , first find the value of x , then add 3.” The primary tool for proving properties about programs
Before you can evaluate a program, you must represent it. While standard compiler courses focus heavily on parsing source code into Abstract Syntax Trees (ASTs), 15-312 introduces a more powerful concept: .
At its core, a programming language serves as a bridge between human logic and machine execution. According to GeeksforGeeks , these languages utilize formal syntax and rules to translate instructions into machine-readable code, forming the basis of software development. – Describe how a program executes step-by-step on
Once you understand the "foundations," you stop seeing languages like Python, Rust, or Haskell as collections of syntax. Instead, you see them as combinations of specific features (e.g., "This is just Hindley-Milner type inference with affine logic"). Verification Skills:
