Course detail
Formal Languages and Compilers
FIT-IFJAcad. year: 2023/2024
This course discusses formal languages and their models. Based on these models, it explains the construction of compilers. The lectures are organized as follows: (I) Basic notions: formal languages and their models, grammars, automata; compilers. (II) Regular languages and lexical analysis: regular languages and expressions, finite automata and transducers, lexical analyzer; Lex; symbol table. (III) Context-free languages and syntax analysis: context-free grammars, pushdown automata and transducers, deterministic top-down syntax analysis (recursive descent), the essence of deterministic bottom-up syntax analysis; Yacc. (IV) Semantic analysis and code generation: semantic checks, intermediate code generation, optimization, code generation.

Rules for evaluation and completion of the course
There is a midterm test for 20 points without a spare or correction term. Students solve one team project during the semester (25 points) that is handed over before given deadline. Exam prerequisites: To be allowed to take the final written exam, the student has to obtain 20 points during the semester; out of these 20 points, at least four points have to be obtained for the programming part of the project.
In case of a serious obstacle (e.g. illness), the student should inform the faculty about that andsubsequently provide the evidence of such an obstacle.
- The midterm test takes place approximately in the middle of the semester without a spare or correction term (20 points). If student cannot attend the midterm test, (s)he can ask to derive points from the evaluation of his/her first attempt of the final exam. To enter the final exam in this case, at least 12 points from project are required.
- To apply theoretical knowledge, students work on a team project (25 points). Continuously, the team leader checks the team's progress. In case of illness of the most team members, the team can ask the responsible teacher to extend the time for the project.
- Finally, there is a final exam with three terms (55 points).
