Typing rules are given in the project assignment.
It is important to read and understand the abstract syntax of mini-C, that is Pfile (parsed trees) and File (typed trees).
Once uncompressed (for instance with tar zxvf parser-java.tar.gz), you get a directory mini-c/. The library java-cup-11a-runtime.jar, provided in sub-directory lib/, must be added to the project (but recent versions of Eclipse and VSCode will do that automatically).
The provided code should compile out of the box. The main method is in file Main.java. It expects a file with extension .c on the command line, possibly with options --debug, --parse-only, and --type-only. If no file is given on the command line, the file test.c (included in the tarball) is used, to ease the tests.
If a lexical or syntax error is detected, it is reported and the program exits with code 1.
If the parsing is successful and option --parse-only is on the command line, then the program exits with code 0.
If a type error is detected, it is signaled using exception Error , with a suitable message string. This exception is caught in Main.java and displayed as
error: ... your message here ...and the program exits with code 1.
int main() { return 0; }This means you only have to consider integer literals in expressions and return statements.
