Gostaríamos de exibir a descriçãoaqui, mas o site que você está não nos permite.In this project, you will implement as Ocaml functions a lexer and parser for SmallC. Your lexer functions will convert a SmallC program internally stored as string into a list of tokens, and your parser functions will consume these tokens to produce an abstract symbol tree (AST). The input could be an entire program, or a fragment of a program ...
