What You Will Do In Your Lab

Consider the following programming problem from CPP w/o Fear, by Overland:

Exercise 05.03.01.txt, p. 126.

Write  a   program  that  randomly   selects  from  a  bag   of  eight
objects. Each object can be red, blue, orange, or green, and it can be
a  ball  or a  cube.  Assume  the bag  contains  one  object for  each
combination (one red  ball, one red cube, one  orange ball, one orange
cube, and so on). Write  code similar to dealer1.cpp, using two string
arrays-- one to identify colors and the other to identify shapes.

1. Download Ex-5-3-1-126.cpp to your local machine, open it in Emacs and save it as "randShapes.cpp." Compile and run it.
   
   
2. Replace the c-style headers with c++ headers. Replace char* with string. Compile and run the new version.
   
   
3. Replace the while loop in main with an eof-controlled while loop that generates this I/O interface:

   % a.out
   Enter no. of items to draw (c-d to exit): 3
   red cube
   red ball
   blue ball
   Enter no. of items to draw (c-d to exit): 2
   green cube
   green ball
   Enter no. of items to draw (c-d to exit): 0
   Exiting..
       

4. Modify draw_an_item() so that it returns a value of type string and does not use cout. Modify main() to call draw_an_item() correctly. Compile and run the new version. (randShapes.cpp now uses the same control structure, headers, and array types as dealer1.cpp.)
   
   
5. The only difference between dealer1.cpp and dealer2.cpp is that dealer2.cpp makes a single call to draw_an_item(). Compare lines 55-56 in dealer1.cpp with lines 50-52 in dealer2.cpp.
   
   Modify randShapes.cpp to use dealer2.cpp's approach. Compile and run the new version.
