What is type checking in programming languages? The process of verifying that the operands of an operation are of compatible types. ○ A way to optimize the execution of a program. ○ Ensuring that all variables are declared before use. Checking if the program will terminate correctly. In operational semantics, what does the notation e → e' represent? OA small step where expression e reduces to expression e'. ○ The execution of a full program. The final output of the program. A rule that type-checks an expression.
