 CS177 C++ Programming, Spring 1998

 Lab 4. Multiple objects and function parameters.

 At the bottom of this message is skeleton source code for a program
 that counts the number of characters and lines typed by the user at
 the keyboard. Complete the skeleton so that it reports the number of
 characters *excluding* newline characters, *and* the number of lines.
 For example, here is sample input and output:

 % a.out
 This is
 some input
 ^D

 Number of lines = 2
 Number of characters = 17
 
 %

  *** YOU MAY NOT BE ABLE TO FINISH THIS ASSIGNMENT IN THE LAB
  SESSION, PLEASE COMPLETE IT IN YOUR OWN TIME. THE DUE DATE IS
  MONDAY, 16TH., IN CLASS ***
 
Follow these steps to complete the assignment.

 1. Edit the source code frm this message exactly as in your
    first assignemnt.
 2. Use the editor to add methods to the Counter class to:
     a) initialize the counter variable
     b) increment the counter
     c) print the value of the counter
     d) print a warning and terminate the program when either
        when the number of characters exceeds 50, or the number
        of lines exceeds 5.
 3. Compile and run the program several times to test its results.
 4. Run the program once more with the the sample input given above.
    Redirect the output to a file, and insert the output into a
    copy of the source code file.
 5. Print the file with the source code and output and hand it to me (RTH).
 6. Mail the same file to our grader (login hhuang).

Points to note:

o You may get compilation errors and/or warnings. Pay attention to these
  messages because you program may not run correctly, or at all, because
  of these errors.
o Don't forget to put your name in the file comment block.
o Termination of keyboard input is signalled by typing a single ctrl-D on
  a separate input line. You can also make the program read from a file by
  using input indirection:

  % a.out < input.file

  There is no need to put a ctrl-D in the file since UNIX will effectively
  put one in for you.
o The skeleton uses the member functions get and eof for the object cin.
  You should not need to alter this.
o You need two counter objects, one to count lines and one to
  cout characters.
o Constructor functions have no return type.
o Terminate the program with a call to exit, thus:
     exit(1);
o You may want to customize the output function (which prints the
  value of the counter) by passing it a string. You can use the
  standard string class to do this:
 
  void print(string str) { cout << str << ... }

  You must include the header file to use sthe string class:

  #include <string>

  (Note there is no .h on it)
