It sounds like you copy and pasted this line:

vector<string> linesVector;

This is a mis-formatted text. It looks like he tried to italicize the line but forgot the closing tag. The is not part of the code.

Again, a big newb here, here is my code

*** Source Snippet Removed ***

How can I get information out of readFile into main?

This is also more of a general question sense I have never done anything past main.

You have to either return it from your function, or you have to pass it in as a reference parameter. In either case your current code is wrong...

std::vector<std::string> readAllLines(std::string const& filename) {  std::vector<std::string> lines;  std::ifstream ifs(filename.c_str());  while (ifs) {    std::string line;    std::getline(ifs, line);    if (ifs) lines.push_back(line);  }  return lines;}int main() {  std::vector<std::string> lines = readAllLines("oogabooga.txt");  std::copy(lines.begin(), lines.end(), std::ostream_iterator<std::string>(std::cout, "\n"));}

... that's why you use a for loop instead of std::copy, and perhaps an "if" statement. You do have to do SOME work for yourself you know...

No offense intended but: A big part of programming is problem solving. That means taking a problem, dissecting it into its various components, and then figuring out how to build a solution based on what you have. If you don't know what to do, the best thing to do is to learn (aka, research, spend time reading, etc). From what I've seen here, you've basically copied and pasted what's been posted, instead of LEARNING what the code that's been posted does. You will never learn anything if you don't start trying to solve the problem yourself. Generally you will never be given the entire solution to a problem, instead people will give you bits and pieces, and your job is to figure out how to take the knowledge you've learned (from those bits and pieces) and put them together or alter them to provide a solution to your problem.

#include <iostream>#include <fstream>#include <string>#include <vector>using namespace std;vector<string> readAllLines(string const& filename) {  vector<string> lines;  ifstream ifs(filename.c_str());  while (ifs)   {    string line;    getline(ifs, line);    if (ifs) lines.push_back(line);  }  return lines;}int main() {  vector<string> lines = readAllLines("text.txt");  int i = lines.size();  cout << i << endl;}
