CSF301-Assignment1

A program designed to parse source code for a custom language (can be seen in t1.txt to t6.txt). The syntax and semantics of the source code are analysed for correctness using parse tree creation and type expression table formation. Any errors in the source code are displayed with line numbers.

Instructions to use the program:

1. make all to compile the code into output.
2. ./output inputcode.txt to run the code, put the source code in inputcode.txt (name can be changed) and grammar in grammar.txt (should be right associative, and unambiguous).
3. make clean to remove all .o files.

• The driving code including the main function is in driver.c.
• All data structure definitions are in customcompiler.h.
• The grammar is in grammar.txt in a format that can be parsed by the program.
• Sample source code for testing the compiler is in t1.txt to t6.txt.
