Question
What is the main difference between a regular grammar and a context-free grammar?1 pointRegular grammars cannot generate infinite languages.Regular grammars can generate context-free languages, but not vice versa.Context-free grammars can generate regular languages, but not vice versa.There is no difference; they are equivalent.
Solution
The main difference between a regular grammar and a context-free grammar lies in their expressive power.
-
Regular grammars are less powerful than context-free grammars. They can only generate regular languages, which are a subset of context-free languages. Regular languages are those that can be expressed with a finite state machine.
-
On the other hand, context-free grammars can generate all regular languages and some languages that are not regular. Context-free languages are those that can be expressed with a pushdown automaton (a finite state machine with an additional stack storage).
So, the statement "Context-free grammars can generate regular languages, but not vice versa." is correct.
