Need help reading a file that has a book format - c++11

Question

I been struggling reading a file that has a book format. The file is broken into pages by a string that looks like this "---------------------------------------". What I'm trying to do is read all the words and keep track of the page number and the word number of every word, the file looks like this
my file
For example if the word "hello" appears in the first page it would looks like this " hello 1,1" because it's the first word on page one if the word would appear in the second page the output will be "hello 2,1"
This is the code I have so far
ifstream inFile;
inFile.open("GreatExpectations.txt");
if(!inFile.is_open()) {
cout << "Error, can't open the file....."<<endl;
return 1;
}
string word;
string separator;
separator = "----------------------------------------";
int pageNum = 0, wordNum = 0;
IndexMap myMap(200000);
string title;
for(int i = 0; i < 2; i++) {
getline(inFile, title);
cout << title <<endl;
}
while(!inFile.eof())
{
inFile >> word;
//cout << word << " ";
wordNum++;
if(word == separator)
pageNum++;
}

If I well understood your question here is my approach to the problem:
#include <iostream>
#include <fstream>
#include <vector>
#include <sstream>
using namespace std;
struct WordInfo {
string word;
int pageNum;
int wordNum;
};
int main() {
ifstream inFile;
inFile.open("GreatExpectations.txt");
if(!inFile.is_open()) {
cout << "Error, can't open the file....."<<endl;
return 1;
}
int pageNum = 1, wordNum = 0;
vector<WordInfo> words; // container for words with informations
// read the file line-by-line
for(string line; getline(inFile, line);) {
// detect the page separator which is a line from hyphens only
if(line.find_first_not_of("-") == string::npos) {
pageNum++;
wordNum = 0;
continue;
}
// process the line word-by-word
stringstream ss(line);
for(string word; getline(ss, word, ' ');) {
wordNum++;
words.push_back({ word, pageNum, wordNum });
}
}
return 0;
}
The WordInfo structure will hold informations from a word as you wanted. It's not the optimal but more simple to read the file line-by-line, so there is two loops: the first reads a line and the second reads the words from that line. If a word is read, it will be pushed into the words vector for later use. That's all.
