Write a context-free grammar for arithmetic expressions consisting of non-negative binary integer numbers defined in Activity 1 and four operators, + (addition), -(subtraction), * (multiplication), and / (division). No precedence or associativity need to be considered in the grammar. In addition, no parentheses can be used in expressions. For example, (10 - 1) * 101 is not acceptable. The regular grammar you have obtained in Activity 1 should be included as part of your solution. Turn in your solution by the date when Section 12.2 is finished.
Transform the context-free grammar obtained in Activity 5 to a pushdown automaton using the algorithm in Section 12.2.2. Turn in your solution by the date when Section 12.3 is finished.
Write parsers for arithmetic expressions. Transform your grammar into a LL(1) grammar. You may need to do a left-factoring of common prefix of productions, and/or to remove any left-recursive productions in the grammar for aritmetic
expressions using the algorithm in Section 12.3.1. Then write a recursive-descent parser for the context-free grammar for arithmetic expressions using the algorithm in Section 12.3.1.
Turn in your solution by the date when Section 12.4 is finished.
