CS 131 - 10 am Lab - Week 9 Lab

*   you CAN compile a C++ class using funct_compile --
    this will check for syntax errors in your class
    definition and implementation;
    
    (give the class name where it asks for the function to
    be compiled)

    *   you CAN use a dynamically-declared instance for testing
        within funct_compile, then (using -> with the method
	name to call the method...)

*   BUT you also are expected to write a function testing
    each new class, that calls all of its constructors
    and tests all of its methods;


    name it: <class>_test,
    and see boa_test.cpp and boa_test.h for an example

    *   note that boa_test is going to create an example boa,
        and produce whether all of its selectors produce
        the expected values for its data fields --

        boa_test needs NO parameters!

        ...put the special C++ keyword void in its signature;

    *   signature: boa_test: void -> bool

*   now: for an example of a function that uses a boa
    (that has a boa parameter),
    see is_boa_portable function

    is_boa_portable

    signature: is_boa_portable: boa double -> bool

    purpose: expects a boa and a carrier's length in meters,
             and produces whether the boa could fit in a
	     carrier of that size

    bool is_boa_portable(boa a_boa, double carrier_len)

    Examples:
    is_boa_portable( *(new boa("green", 12, "lasagna")), 2) == false
    is_boa_portable( *(new boa("green", 12, "lasagna")), 22) == true
    is_boa_portable( *(new boa("green", 12, "lasagna")), 12) == true

    bool is_boa_portable(boa a_boa, double carrier_len)
    {
        return a_boa.get_length() <= carrier_len;
    }

*   (then, lab exercise)
