| || ||Familiarity with formal languages and their models. Grasp of compiler construction.|
| || ||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.|
|Knowledge and skills required for the course:|
| || ||Knowledge of discrete mathematics.|
|Learning outcomes and competences:|
| || ||Fundamental familiarity with the theory of formal languages. Ability of a compiler construction.|
|Syllabus of lectures:|
- Formal languages.

- Regular languages and their models: regular expressions and finite automata.
- Lexical analysis: lexical analyzer; Lex; symbol table.
- Context-free languages and their models: context-free grammars and pushdown automata.
- Syntax analysis: deterministic syntax analysis, FIRST and FOLLOW, LL grammars.

| || ||The midterm test takes place approximately in the middle of the semester without a spare or correction term (20 points). To apply theoretical knowledge, students work on a team project (25 points). Continuously, the team leader checks team's progress. Finally, there is a final exam with two correction terms (55 points).|
| || |
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.
| || ||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 has to be obtained for the programming part of the project.|
