Count the number of unique words and occurrence of each word in this program?

Count the number of unique words and occurrence of each word in this program?

CSCI-15 Assignment #2, String processing. (60 points) Due 9/23/13
You MAY NOT use C++ string objects for anything in this program.
Write a C++ program that reads lines of text from a file using the
ifstream getline() method, tokenizes the lines into words ("tokens") using
strtok(), and keeps statistics on the data in the file. Your input and
output file names will be supplied to your program on the command line,
which you will access using argc and argv[].
You need to count the total number of words, the number of unique words,
the count of each individual word, and the number of lines. Also, remember
and print the longest and shortest words in the file. If there is a tie
for longest or shortest word, you may resolve the tie in any consistent
manner (e.g., use either the first one or the last one found, but use the
same method for both longest and shortest). You may assume the lines
comprise words (contiguous lower-case letters [a-z]) separated by spaces,
terminated with a period. You may ignore the possibility of other
punctuation marks, including possessives or contractions, like in "Jim's
house". Lines before the last one in the file will have a newline ('\n')
after the period. In your data files, omit the '\n' on the last line. You
may assume that the lines will be no longer than 100 characters, the
individual words will be no longer than 15 letters and there will be no
more than 100 unique words in the file.
Read the lines from the input file, and echo-print them to the output
file. After reaching end-of-file on the input file (or reading a line of
length zero, which you should treat as the end of the input data), print
the words with their occurrence counts, one word/count pair per line, and
the collected statistics to the output file. You will also need to create
other test files of your own. Also, your program must work correctly with
an EMPTY input file – which has NO statistics.
Test file looks like this (exactly 4 lines, with NO NEWLINE on the last
line):
the quick brown fox jumps over the lazy dog.
now is the time for all good men to come to the aid of their party.
all i want for christmas is my two front teeth.
the quick brown fox jumps over a lazy dog.
Copy and paste this into a small file for one of your tests.
Hints:
Use a 2-dimensional array of char, 100 rows by 16 columns (why not 15?),
to hold the unique words, and a 1-dimensional array of ints with 100
elements to hold the associated counts. For each word, scan through the
occupied lines in the array for a match (use strcmp()), and if you find a
match, increment the associated count, otherwise (you got past the last
word), add the word to the table and set its count to 1.
The separate longest word and the shortest word need to be saved off in
their own C-strings. (Why can't you just keep a pointer to them in the
tokenized data?)
Remember – put NO NEWLINE at the end of the last line, or your test for
end-of-file might not work correctly. (This may cause the program to read
a zero-length line before seeing end-of-file.)
This is not a long program – no more than about 2 pages of code
Here is what I have so far:
#include<iostream>
#include<iomanip>
#include<fstream>
#include<string>
#include<cstring>
using namespace std;
void totalwordCount(ifstream &inputFile)
{
char words[100][16]; // Holds the unique words.
char *token;
int totalCount = 0; // Counts the total number of words.
// Read every word in the file.
while(inputFile >> words[99])
{
totalCount++; // Increment the total number of words.
// Tokenize each word and remove spaces, periods, and newlines.
token = strtok(words[99], " .\n");
while(token != NULL)
{
token = strtok(NULL, " .\n");
}
}
cout << "Total number of words in file: " << totalCount << endl;
}
void uniquewordCount(ifstream &inputFile)
{
char words[100][16]; // Holds the unique words
int counter[100];
char *tok = "0";
int uniqueCount = 0; // Counts the total number of unique words
while(!inputFile.eof())
{
uniqueCount++;
tok = strtok(words[99], " .\n");
while(tok != NULL)
{
tok = strtok(NULL, " .\n");
inputFile >> words[99];
if(strcmp(tok, words[99]) == 0)
{
counter[99]++;
}
else
{
words[99][15] += 1;
}
uniqueCount++;
}
}
cout << counter[99] << endl;
}
int main(int argc, char *argv[])
{
ifstream inputFile;
char inFile[12] = "string1.txt";
char outFile[16] = "word result.txt";
// Get the name of the file from the user.
cout << "Enter the name of the file: ";
cin >> inFile;
// Open the input file.
inputFile.open(inFile);
// If successfully opened, process the data.
if(inputFile)
{
while(!inputFile.eof())
{
totalwordCount(inputFile);
uniquewordCount(inputFile);
}
}
return 0;
}
I already took care of how to count the total number of words in the file
in the totalwordCount() function, but in the uniquewordCount() function, I
am having trouble counting the total number of unique words and counting
the number of occurrences of each word. Is there anything that I need to
change in the uniquewordCount() function?
