Need to write a function that adjusts words in a string array

Rick

I have a program that reads from a file. In the file are a series of
words. I read in all the words into a string array, find the average
length, count the number of words, display the longest word and how long
it is, and display the smallest word and how long it is. All that is
working fine, but what I need to do it format certain words that contain
a period at the end of them (ex: a word at the end of a sentence), words
with quotes around them, exclamation points, etc. If a word has one of
these characters anywhere but the beginning or end it is ok. Also, say
you have this word: one." It needs to be changed to: one

The word: don't is ok because the "'" isn't at the beginning or end.

That task can easily be accomplished with regular expressions. Look at
Regex++ (http://www.boost.org/libs/regex/index.htm), included in Boost.

It needs to be done basically with if/for/while loops.

How do I check if tempword[0] equals a '

I get an error when I do tempword[0] == '''

How do I format it different?

void convertarray(string words[], int count)
{
//int firstpos;
int lastpos;
string tempword;
int length;

for(int i = 0; i < count; i++)
{
//firstpos = 0;
tempword = words[i];
lastpos = tempword.length() - 1;
if(tempword[0] == '!' || tempword[0] == '(' || ')' || tempword[0]
== '"' || tempword[0] == '?' ||
tempword[0] == '.' || tempword[0] == ':' || tempword[0] == ';' ||
tempword[0] == ''' ||
tempword[0] == ',')
{
length = tempword.length();
for(int j = 0; j < length - 1; j++)
tempword[j] = tempword[j + 1];
}
}
}

Ok, this is what I have right now. It's not working quite properly and
I still need to check to see if the first character is a: '

For some reason every word is being converted even though some should
make the if statement false.

void convertarray(string words[], int count)
{
//int firstpos;
int lastpos;
string tempword;
int length;
bool yes;

for(int i = 0; i < count; i++)
{
tempword = words[i];
lastpos = tempword.length() - 1;
if(tempword[0] == '!' || tempword[0] == '(' || ')' || tempword[0]
== '"' || tempword[0] == '?' ||
tempword[0] == '.' || tempword[0] == ':' || tempword[0] == ';' ||
tempword[0] == ',')
{
length = tempword.length();
for(int j = 0; j < length - 1; j++)
tempword[j] = tempword[j + 1];
words[i] = tempword;
}
else
{
words[i] = tempword;
}
}
}

Try tempword[0] == '\''

The backslash tells the compiler that you want it to use the second ' as a
literal character, not as a quote mark to delimit another character (its
normal function in a C++ statement).

I got that, but I'm still not getting the desired output. Here is what
I have so far:

void convertarray(string words[], int count)
{
int lastpos;
string tempword;
int length;
bool yes;

for(int i = 0; i < count; i++)
{
tempword = words[i]; //file?
lastpos = tempword.length() - 1; //4
if(tempword[0] == '!' || tempword[0] == '(' || ')' || tempword[0]
== '"' || tempword[0] == '?' ||
tempword[0] == '.' || tempword[0] == ':' || tempword[0] == ';' ||
tempword[0] == ',' ||
tempword[0] == '\'')
{
cout << "first position matches" << endl;
length = tempword.length();
for(int j = 0; j < length + 1; j++)
tempword[j] = tempword[j];
words[i] = tempword;
}
if(tempword[lastpos] == '!' || tempword[lastpos] == '(' ||
tempword[lastpos] == '"' ||
tempword[lastpos] == '?' || tempword[lastpos] == '.' ||
tempword[lastpos] == ';' ||
tempword[lastpos] == ',' || tempword[lastpos] == '\'')
{
cout << "last position matches" << endl;
length = tempword.length(); //4
for(int k = 0; k < length; k++)
tempword[k] = tempword[k];//file
words[i] = tempword;
}
else
{
cout << "no position matches" << endl;
words[i] = tempword;
}
}
}

Devloping debug techniques is something you need to learn.
Just in case you don't have a debugger (which would simplify
things) why not insert some output statements at strategic
positions to enable yourself to watch what the program
is doing and why.

eg.

void convertarray(string words[], int count)
{
int lastpos;

bool yes;

for(int i = 0; i < count; i++)

tempword = words[i]; //file?

tempword[j] = tempword[j]; }
words[i] = tempword;
cout << "new word is " << tempword << endl;

// note: the above loop does .... nothing

What should I use as a debugger? Basically I am just writing it in emacs
and compiling with g++.
