Question 1
What is the main purpose of a derivation in a CFG?
- To visualize strings
- To generate terminal strings
- To define non-terminals
💡 Hint: Think about what we are trying to achieve from the starting point.
Question 2
True or False: A parse tree only shows terminal symbols.
- True

Challenge Problems
Push your limits with challenges.
Question 1
Develop a complete CFG for a simple programming language that allows basic arithmetic expressions. Derive the string (2 + 3) * (4 - 1) and create its parse tree.
💡 Hint: Focus on breaking the expression down into terms and operations.
Question 2
Analyze why parse trees are important for syntax checking in compiler design. Provide examples of scenarios where derivation errors could affect program execution.
💡 Hint: Think about how structure relates to error detection in code.
