What would you expect from the following courses?

• CSE331: Operating Systems
• CSE321: Database Systems
• CSE411: Introduction to Compilers

Goals of This Course

1. Understand basic concepts of programming languages.
2. Develop a system that can run a program written in a programming language.

Interpreter vs Compiler

• Python Interpreter

                    Uni
                     ↓
hello-name.py → [ python ]
                     ↓
                  Hello Uni   

• Clang Compiler

                             Uni
                              ↓
hello-name.c → [ clang ] → hello-name
                              ↓
                          Hello Uni   

Will I be more proficient in C (Java, C++, Rust ...) after taking this course?

List of Programming Languages

What you can expect from this course

• You will not be afraid of learning new languages.
• You will be able to design your own language. Why not?

Are you interested in research on software?

• Do you want to improve or invent a compiler for a new or existing CPU/GPU architecture?
• Do you want to analyze a program to find bugs or security vulnerabilities and fix them automatically?
• Do you want to make large language models better handle programming tasks?

Which programming language will we use?

                                           Uni
                                            ↓
a program written in language A → [ interpreter written in language B ]
                                            ↓
                                        Hello Uni
