![]() In Dynamic Type Checking, types are associated with values, not variables. It catches wrong return types, like return “70”, from a function that’s declared to return an int.ĭynamic Type Checking is defined as the type checking being done at run time.It catches the wrong number of arguments.It catches wrong names like Math and Predefined Naming.It catches syntactic errors like spurious words or extra punctuation.The compiler must check that the same name is used at both places. For example in Ada, a loop may have a name that appears at the beginning and end of the construct. Name-related checks: Sometimes the same name may appear two or more times.For example, in Pascal an identifier must be declared uniquely, labels in a case statement must be distinct, and else a statement in a scalar type may not be represented. Uniqueness checks: There are situations in which an object must be defined only once.For example, a break statement in C causes control to leave the smallest enclosing while, for, or switch statement, an error occurs if such an enclosing statement does not exist. The flow of control checks: Statements that cause the flow of control to leave a construct must have someplace to which to transfer the flow of control.For example, if an array variable and function variable are added together. ![]()
