A compatible type is one that is … WebIn static type checking, the type of variable is known at compile time (it checks the type of variable before running). Typical examples of static checking are: • Type checks: Report an error if an operator is applied to an incompatible operand. • Flow-of-control checks: Statements that results in a branch need to be terminated correctly.
