Which of the following statements are correct for recursion?

a. Recursion is available only in the C and C++ languages.
b. Recursion is available in all programming languages.
c. Recursion is available in most modern programming languages, including C++.
d. Recursion is a preprocessor technique
e. Recursion, if used with care can be a useful programming technique.

c) and e)
Explanation: Part a) is in error, one has only to note almost any programming language designed since FORTRAN, though the student will only know the statement in a) from the text. Part b) is false, since there are some languages that do not support recursion. The text asserts “most modern languages … all functions [to be] recursive.”. This is part c). Part d) The preprocessor may provide recursion, but this writer has never seen it used. e) This statement is a direct quote from the text. Experience with C++ and other programming languages bears this out.
