I want to count the number of syllables in the words in a text file. In my code I am getting the count of words contained in the text file but am getting one more than present.

#include <iostream>
#include <string>
#include <math.h>
#include <fstream>
using namespace std;
int main()
{
double index=0;
int syllabus,words=0,sentences;
string filename,word;
cout << "Enter the data file name: ";
cin >> filename;
ifstream infile;
infile.open(filename.c_str());
if(infile.fail())
{
cout << "Error opening " << filename << endl;
system("pause");
return 1;
}
while(!infile.eof())
{
cout << word << endl;
infile >> word;
words++;
}
cout << words << endl;
infile.close();
system("pause");
return 0;
}

I think my problem is at the !infile.eof line of code.

I am working on a text book problem that involves the Flesch Readability Index.

while(!infile.eof())
{
cout << word << endl;
infile >> word;
words++;
}

Why do you output the previous word instead of outputting the word that came from the file?

I am not very familiar with the C++ stream classes, but it looks like, when you are at the end of the file, it needs to try to read a word before finally setting the "eof" flag to true. So, you have to account for that one failure at the end. You could try to make sure the contents of "word" look like a real word before increasing your count. The fanciness of your filter is up to you. I'll start with size.

while(!infile.eof())
{
    std::string word;
    infile >> word;
    cout << word << endl;
    if (word.size() > 0)
        words++;
}
