War and Peace
This assignment will give you practice with C++ strings and vectors.
Download and unzip the complete text of War and Peace as an ASCII file from
http://www.cs.sjsu.edu/~mak/CS144/assignments/3/WarAndPeace.txt
The file contains over 65,000 lines and over a half million words. This file has already
been uploaded to CodeCheck.
Write a C++ program to search for the following names in the text:
• Makar Alexeevich
• Joseph Bazdeev
• Boris Drubetskoy
Scan (read and search) the input file a line at a time. For each occurrence of each name
in an input line, print:
• The line number (first line is 1).
• The character position of the first letter of the first name (first position is 1).
• The name itself.
Print the names in line number order. A name can be split across two consecutive lines.
In that case, print the line number of the first name. If you find more than one name in a
line, print the names in alphabetical order.
You may assume that the names in the input file are always in the order of the first name
followed by the last name. Between the first and last names, there is either a single
space or a line break. If a name is split across two lines, the first name will be at the end
of one line, although there may be one or two blanks between the last letter and the line
break, and the last name will always be the first character of the next line.

Strings and vectors
You must use C++ strings and not the old C strings, and you must use vectors instead of
arrays. Use the vector at method instead of indexing with [ and ].
For string functions, see http://www.cplusplus.com/reference/string/string/
For vector functions, see http://www.cplusplus.com/reference/vector/vector/
Functions
You must have good functional decomposition. Follow the convention of declaring your
functions before the main. Include documentation (comments) for each declaration:
• the purpose of the function and any assumptions (preconditions) that it makes
• what each parameter is; use @param
• what is the result (postcondition); use @return if it is not void
Pass nonscalar parameters by reference
to avoid unnecessarily copying argument
values. Mark with const any parameters
whose values the function isn’t supposed
to change. Define the functions after the
main. Document the internals of each
function, but do not repeat the
documentation of its declaration.
Avoid the use of global variables. Use
function parameters instead. Global
constants are OK.
Expected output
CodeCheck will check your output for
correct values and for formatting.

Tips
Write the first version of your program to find only names contained in a single line. Your
second version can find names that are split across two lines.
If you search each line for the names in alphabetical order and there are more than
name in the line, you will find the names in alphabetical order.

Academic integrity
You may study together and discuss the assignments, but what you turn in must be
your individual work. Assignment submissions will be checked for plagiarism using
Moss (http://theory.stanford.edu/~aiken/moss/). Copying another student’s
program or sharing your program is a violation of academic integrity. Moss is
not fooled by renaming variables, reformatting source code, or re-ordering functions.
Violators of academic integrity will suffer severe sanctions, including academic
probation. Students who are on academic probation are not eligible for work as
instructional assistants in the university or for internships at local companies.
