That is both off-topic and incorrect.
C does not have a string type. C certainly does have strings. The
definition is quoted above.
The C standard makes extensive use of the term "string", particularly in
the library section. The meaning is clear and unambiguous. Removing
the definition from the language would require a great deal of work to
update the standard, and would have no benefit.
