-In ProgrammingLanguages a variable is a name potentially associated with a value in the context of the SourceCode.
-
-In the (meaningless)
[C]/[C++] code:
- int blarg() {
- char c = 'a';
- int count = 12;
- int i;
- for (int i=;i<count;i++)
- c++;
- return (int) c;
- }
-
-c, count and i are variables. i is a
variable which is initially undefined (called unbound in some languages). In [C] and [C++] function definitions are not variables, although they are in [Lisp] and [Scheme
]. In some langauges (including all pure FunctionalLanguages) variables and in some contexts (const variables in [C]/[C++]) variables cannot be changed.
-
-Names associated with values in data (for example [HashTable]s) are not considered variables because they are not in the context of SourceCode.
