The primary difference between natural languages and programming languages
is that natural languages are inherently ambiguous-- in phonology
morphology, syntax and meaning.

Programming languages are engineered not to be ambiguous.
In general, they are usually describable by context-free phrase
structure grammars--

The problems associated with the elaboration of higher-level programming
languages has resulted in a literature dealing with the 'semantics' of
programming languages, and occasional problems of ambiguity which may
enter, unavoidably, because of their complexity.

It worth noting that computer science students have no trouble
earning top A's in Linguistics Dept. courses in syntax, but that
most students in Linguistics have trouble earning A's (or even B's)
in middle-level Computer Science Dept. courses.
