15-312: Foundations of Programming Languages

is a rigorous undergraduate course at Carnegie Mellon University that treats programming languages as mathematical objects rather than just collections of features. Course Overview

Programming languages are the backbone of computer science, enabling humans to communicate with computers and create software that can solve complex problems. The first programming languages, such as Assembly and Fortran, emerged in the 1950s, and since then, numerous languages have been developed, each with its strengths and weaknesses. The study of programming languages is essential for computer science students, as it helps them understand the fundamental concepts of programming, software development, and computer science. 15312 foundations of programming languages

Structural Operational Semantics

Once the structure is defined, we apply . This framework uses inference rules to describe the step-by-step execution of a program. By defining "transition systems," we can mathematically trace how a program state evolves, transforming the act of execution from a black-box mystery into a predictable, logical progression. The Role of Type Theory 15-312: Foundations of Programming Languages is a rigorous

When you understand type safety, you understand why a compiler rejecting your code is a feature . Languages with strong foundations (Rust, Haskell, OCaml) allow you to change 50% of your codebase, and if it compiles, it likely works.

Type Inference:

How a compiler can figure out what you mean without you telling it.
