2. Given the following Python function prototypes, classify each function call as legal or illegal. Circle one. def f(a, *b): def g(a, b=16):

   1. f(1, 2, 3) LEGAL ILLEGAL

   2. f(1) LEGAL ILLEGAL

   3. f(1, 'hello', 2) LEGAL ILLEGAL

   4. g(b=2, a=4) LEGAL ILLEGAL

   5. g(32) LEGAL ILLEGAL

3. (12 points) Given the following C# function prototype, classify each function call as legal or illegal. Circle one. public static void f(params int [] args) { ... }

   1. f(1) LEGAL ILLEGAL

   2. f(1, "hello", 2) LEGAL ILLEGAL

4. (12 points) A void C++ function named f receives one 2D int matrix consisting of 100 rows and 50 columns. Identify function distinct signatures that could be used for this function. Circle one for each answer. For those that are unacceptable, describe why it is an error.

   1. void f(int M[100][50]) ACCEPTABLE UNACCEPTABLE If unacceptable, describe why:

   2. void f(int M[][50]) ACCEPTABLE UNACCEPTABLE If unacceptable, describe why:

   3. void f(int M[100][]) ACCEPTABLE UNACCEPTABLE If unacceptable, describe why:

   4. void f(int M[][]) ACCEPTABLE UNACCEPTABLE

If unacceptable, describe why:
