Provided Files:
• A1.c - A lexical analyzer program (written in C) for simple arithmetic expressions.
• A1.java - A shell file with a main method and the header information.
• input1.txt - A sample input file.
• input2.txt - A sample input file.
• output1.txt - The required output for the example input1.txt file.
• output2.txt - The required output for the example input2.txt file.
Description: Convert the C implementation of lexical analyzer A1.c to an equivalent Java program. Given a particular input, your Java program should produce the same output that A1.c produces. Use a diff tool to ensure your program produces the correct output. Even minor differences in output will cause you to fail grading tests and lose points.
Submission: your A1.java file.
General Programming Assignment Requirements:
• Classes must be in the default (no package statement) unless otherwise specified. You will lose 20 points (all points) if you put a package statement in your program.
• If your program that does not compile or does not run, you will lose all points.
• If you submit the wrong file your grade will suffer accordingly. Most likely a 0.
• Screen shots with time stamps of "last modified" from your system are proof of nothing. It is trivial to change the system time on computers or to Photoshop "evidence".
• Likewise if I ask for the source code, the .java file, and you submit the .class file your grade will be 0.
Checklist: Did you remember to:
• worked on the programming assignment by yourself?
• fill in the header in your file A1.java?
• ensure your program does not suffer a compile error or runtime error?
• ensure your program creates the correct output and that it matches the expected output exactly?
• put a comment at the start of each method describing in broad terms, what it does?
• properly indent your source code so that your indenting is readable and consistent?
• use good names for variables to make your program easy to understand?
