Homework SourseA compiler converts a source language program into machine l
A compiler converts a source language program into machine language. There are some basic stages of compilation: scanning, parsing, semantic analysis, and code generation. For this assignment, you will implement a scanner and parser for a small language with its grammar given in BNF notation. Grammar 1: => ! => | => | => ( ) | identifier => + | - => * | / Apart from a few minor modifications, this is almost the same as the grammar for the in-class exercise we did recently: Grammar 2: => ! => { (+|-)} => {(*|/) } => ( ) | identifier You may use either grammar for your implementation. Choose the representation that is more intuitive to you. The terminal identifier isn’t a terminal in the language- it stands for any upper or lower case letter. However, it is shorter and cleaner to substitute the word identifier in the grammar. This grammar uses the exclamation point symbol to mark the end of the expression. Miscellaneous 1. You may use C, C++, or Java to write your program. Your program must compile using one of the compilers on Pluto (indicate which one). 2. You may work in group, 2 people max. When you submit your assignment, indicate your team member in your documentation file. 3. You may not use any software libraries (third party or otherwise) which do scanning, parsing, or pattern matching
