a) Let a program store the result of applying the eval function to the rst command-line argument. Print out the resulting object and its type. b) Run the program with different input: an integer, a real number, a list, and a tuple.

Hint On Unix systems you need to surround the tuple expressions in quotes on the command line to avoid error message from the Unix shell.

c) Try the string "this is a string" as a command-line argument. Why does this string cause problems and what is the remedy? Filename: objects_cml.
