WHAT HAPPENED: mistyped one of ring_area's examples during funct_play run!

TO FIX: using nano to fix examples *comment* in ring_area.cpp

(in nano:

• control-o and then enter to save,
• control-x to exit nano)

[st10@nrs-labs lab8]$ nano ring_area.cpp

THEN: using nano to fix example's displayed and actual call in ring_area_ck_expect.cpp

[st10@nrs-labs lab8]$ nano ring_area_ck_expect.cpp

THEN: using funct_compile to re-compile ring_area

[st10@nrs-labs lab8]$ funct_compile
----------------------------------------------
Welcome to the 03-13-13 version of funct_compile!
----------------------------------------------

Are there any already-created C++ functions OR CLASSES (in the current 
   working directory) which the function to be compiled uses?
   (type y if so, n if not)
your answer: y

Enter the name of an already-created function or class (created in the
   current directory), or q to quit:
function or class name: circ_area

Enter the next name of an already-created function or class (created
   in the current directory), or q to quit:
function or class name: q

What is the name of your function?
(note: this script assumes this function is in a file in
   the current working directory named after the function
   and ending with .cpp)
function name: ring_area

COMPILING ring_area.cpp...
-----------------------------------------------------------------
ring_area.cpp COMPILED! 8-)
trying to compile ring_area_ck_expect.cpp...

Would you like to run ring_area_ck_expect?
   (type y if so, n if not)
your answer: y


testing ring_area: true's should mean passed: 
---------------------------------------
(abs(ring_area(10, 1) - (314.159 - 3.14159)) < .001): true
(abs(ring_area(2, 1) - (circ_area(2) - 3.14159)) < .001): true


Enter a C++ expression involving:
ring_area
circ_area
...and type enter
   (or type q to quit):
q

Quitting funct_compile ... goodbye.
