What is the role of evaluation context/environment in operational semantics? They specify the program's memory structure. They define how terms (variables) should be reduced/evaluated They check the type of an expression. They determine the final output of a program. What is the difference between static and dynamic type checking? Static type checking occurs at compile-time, while dynamic type checking occurs at runtime. ○しろまる Static type checking is faster than dynamic type checking. Dynamic type checking ensures that the program will not crash. Static type checking allows types to change during execution.
