For this exercise, we will work on a regular grammar to recognize a comment in a C++ or Java program. A comment starts with /* and ends with */ and anything else in between can be ignored. We won't consider th case of nested comments. Keep in mind that you can have any number of * characters at the beginning, at the end, and in between. • Write a regular grammar recognizing such comments. • Draw the finite state machine for this grammar. • Draw a table for this grammar such as the ones for table-driver scanners in the class notes and in the book.

Question

For this exercise, we will work on a regular grammar to recognize a comment in a C++ or Java program. A
comment starts with /* and ends with */ and anything else in between can be ignored. We won't consider the
case of nested comments. Keep in mind that you can have any number of * characters at the beginning, at the
end, and in between.
• Write a regular grammar recognizing such comments.
• Draw the finite state machine for this grammar.
• Draw a table for this grammar such as the ones for table-driver scanners in the class notes and in the

Design FSMs that will recognise the following languages. Some of these languagesare given simply as sets of strings (and hence there should be no doubt what themachine must recognise). Others are described using English, and there may wellbe a lack of clarity in these descriptions. You should make clear any assumptionsthat you have made in interpreting what the machine needs to do. The alphabetfor all the machines is {x,y, z}.1. {xy, xz}.2. Two x symbols followed by one y and zero or more zs.3. {xxy, xzy, xy}.4. At least one x followed by exactly one y followed by zero or more zs.
