WebGrammars are an important tool for describing languages. The course on Languages and Parsing gives many examples of grammars. The applications that have been used to introduce the different kinds of grammar formalisms range from grammars for natural languages to programming languages, to languages used to describe growth in biology. WebEngineering Computer Science 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.
