Exam 7: Basic Semantics

In C++,declarations that bind all potential attributes are called ____.

Names can be reused within nested blocks by associating each declaration with a level number and an offset.

____ are any storable quantities,such as integers.

When a nonlocal name is used in an expression,the declaration that applies to that name cannot be determined until execution time under dynamic scoping.

Each function call generates a region of allocated memory associated with the function; this is called an activation record.

The meaning of a name cannot be determined by the attributes associated with it.

____ are generally bound at load time.

In a block-structured language with heap allocation,there are three kinds of allocation: static (for global variables),automatic (for local variables),and dynamic (for heap allocation).

If an operator can be used to perform more than one operation,it is said to be shadowed.

Static constants are always computed at load time.

Dynamic allocation places variables ____.

Declarations in surrounding blocks are called nonlocal declarations.

The scope of a binding is ____.

The body of an externally defined function will not be bound until ____.

The bindings of names to storage locations is called the ____.

Each call to a method is referred to as a(n)____.

Lexical scoping rules are sometimes called dynamic scoping.

The declaration before use scoping rule in C allows any declaration to be used as long as it is declared within the current block.

In object-oriented languages such as Java and Smalltalk,the ____ is the only declaration that does not itself need to be inside another class declaration.

Java requires manual deallocation of objects.
