Update the shared working copy.

 cd                        # Go to your home directory
 cd cs23021_shared         # Go into the shared working copy
 svn update                # Do the update

Create directory for the project.

 cd                                           # Go to your home directory
 cd cs23021                                   # Go into your working copy
 svn mkdir Phonebook                          # Create dir for the project
 ll                                           # Notice the new directory
 svn commit -m "Phonebook project directory"  # Commit

A file with the main function is provided in a file named phonebook_main.cpp.

Copy the file phonebook_main.cpp.

 cd                                                     # Go to your home directory
 cd cs23021                                             # Go into your working copy
 cd Phonebook                                           # Go into new directory
 cp ../../cs23021_shared/Phonebook/phonebook_main.cpp . # Copy provided file
 svn add phonebook_main.cpp                             # Add file with main
 svn commit -m "Phonebook project provided file"        # Commit

Copy the Makefile.

 cd                                            # Go to your home directory
 cd cs23021                                    # Go into your working copy
 cd Phonebook                                  # Go into Phonebook directory
 cp ../../cs23021_shared/Phonebook/Makefile .  # Copy make file to current dir
 svn add Makefile                              # Add make file
 svn commit -m "Phonebook project make file"   # Commit

Create empty files to get started.

 touch phonebook.h phonebook.cpp            # Create empty files
 svn add phonebook.h phonebook.cpp          # Add empty files
 svn commit -m "Empty initial files"        # Commit

Implement as described below.

1. phonebook_main.cpp - provided
2. phonebook.h - you create, contains the definitions for the specified structures and the declarations for the specified functions
3. phonebook.cpp - you create, contains the definitions for the specified functions

 struct PB_Entry
 {
     std::string _name;
     int         _number;
 };

 struct Phonebook
 {
     std::string           _file_name;
     std::vector<PB_Entry> _entries;
 };

Define the following functions in the file phonebook.cpp.

• Open a file using the filename in the Phonebook object, error checking should be done. The file will be of the form:

    nameA  23
    nameB  931
    nameC  3526
    nameD  222
  

  Create a file with the above structure, use whatever contents you like.
• Read in the pairs of values, use the following while loop condition:
  in >> inStr && in >> inVal
• Create a PB_Entry object and store the input values in it.
• Use push_back() to put the PB_Entry object in the phonebook's vector.
• Close the file.

• Search the vector for an occurrence of the second argument. Use a sequential search.
• Return the index in the vector if found, else return -1.

• Search the vector for an occurrence of the second argument. Use a sequential search.
• Return the index in the vector if found, else return -1.

• Create a PB_Entry object and store the parameter values in it.
• Use push_back() to put the PB_Entry object in the phonebook's vector.

• Output all the name/number pairs, each pair on its own line. The format should be similar to the input file however the exact format is not important.

• Open a file using the filename in the Phonebook object, error checking should be done.
• Write the name/number pairs to the file one pair per line. The format should be similar to the input file.
• Close the file.

  make          # Compile the program, executable is named phonebook
  make pbfile   # Generate an phonebook file named pb.txt
  make clean    # Remove .o files and the executable

  ./phonebook phonebook_file

1. In the header file put the struct definitions and the function declarations.
2. Write stubs for each function, compile, and run. (A stub is a function with an empty body and a return with a reasonable value.)
3. Compile. The program should compile at this point. If it doesn't compile now it won't compile later and it will be harder to figure out why later.
4. Commit.

    svn commit -m "structs defined, stubs in, compiles"     # Commit
   

   Commit regularly.
5. Implement the input() function. Temporarily put a cout after the values are stored so that you may see the values that are actually input. Including extra output statements is a handy debugging tool, however do not leave them in the finished product.
6. Compile and run. Commit.
7. Implement the outputAll() function. Delete the cout from input().
8. Compile and run. Test the outputAll() function. Commit.
9. Implement the remaining functions, one at a time, in any order.

• Your code must work with the given main function file.
• Do not leave any debugging outputs in the code you turn in.

• Have the source code in the repository.
