Contributions summary:Enrico primarily contributed to the implementation of SMT2 array theory features within the CBMC project. They added functionality for the "store" operation, including validation and testing. Further work involved adding and testing for multi-dimensional arrays, and `__CPROVER_bool` arrays within the project. In addition, they added support for converting `is_invalid_pointer_exprt` and `nondet_symbol_exprt` expressions to SMT2.
