Tue/False 25 True/False The term binding is an association between an entity and a property A binding is static if the association occurs at run-time. The lifetime of a variable name refers to the time interval during which it has memory is allocated. The scope of a name is the collection of statements which can access the name binding. In yamic scoping, bo t caio of staments acn i the source pograun The rules used for a Type Checking can be expressed with EBNF A language is statically typed if the type of all the variables are fixed when they are declared In both dynamic and statically typed programming languages, variables must be definite before use A scope resolution operator is a mechanism provided for referencing a name hidden by an inner nested scope The dope vector stores the element size, element type, and the number of elements of an array. A type conversion is a narrowing conversion if the source type has fewer bits that does the destination. In C, global variables declared static can't be accessed from another other compilation unit (i.e file) The construct un ion breaks type checking systems (render them ineffective). In program languages with dynamic typing, variables do not require type declaration before they are used With name equivalence, types are considered equivalent if they have the same names. A name will be visible from anywhere in its referencing environment. With C like programming languages, the range of values, of a variable, are not known at compile time With structure equivalence, types are considered equivalent if they have to have the same structure
