Input a few examples of your own and demonstrate your program works. 2. Design a DFA that could recognize variable names consists of only letters and integers, then translate that design into a working program. Input a few examples of your own and demonstrate that it works. 3. Using the bottom up parser (see the attached file) for the simple expression grammar, implement the bottom-up parsing algorithm in a progam. Input a few sentences to your program, and show that your parser does work. 4. Using the code generation routines from the hand-outs, show that your parser in 3 generates the right codes corresponds to the input expressions . 5. Finally, combine all 1,2,3,4 together into a single program and input expressions with different variable names, and show that the corresponding code generation works. 6.
