Explicit heap-dynamic variables
What is the range of statements in which a variable is visible known as?
Scope
In which scoping method are names bound to nonlocal variables based on spatial relationships?
Static scoping
Which category of variables are bound to heap storage only when they are assigned values?
Implicit heap-dynamic variables
What is the process that involves storage allocation and binding indicated by a declaration statement?
Elaboration
Which type of variable remains bound to memory cells from program execution start to end?
Static variables
What is the range of statements in which a variable can be referenced in known as?
Scope
'Explicit heap-dynamic' and 'implicit heap-dynamic' variables differ in their:
Value assignment mechanism
Stack-dynamic variables have their storage bindings created after program execution begins.
False
Explicit heap-dynamic variables are bound to memory cells before program execution starts.
False
Implicit heap-dynamic variable attributes are bound every time they are assigned values.
True
Static scoping is the same as dynamic scoping.
False
The scope of a variable is the same as the range of statements in which the variable is visible.
True
Dynamic scoping is based on spatial relationships between subprograms.
False
Stack-dynamic variables are always statically bound.
False
Explicit heap-dynamic variables have names.
False
Implicit heap-dynamic variables get bound to heap storage regardless of value assignment.
False
Static scoping binds names to nonlocal variables based on calling sequence of subprograms.
False
Learn about the concept of binding in programming, including how it associates attributes and entities like variables and operations. Explore the different times at which binding can occur and the distinctions between static and dynamic binding.
