C++ Vectors

This is my first time working with Vectors and I'm getting LNK errors
Here's my isolated code.

#include <iomanip>
#include <string>
#include <iostream>
#include <cstdlib>
#include <vector>
#include <fstream>
using namespace std;

void input(ifstream& in, ofstream& out, vector<double> item_ID);


int main()
{
    vector<double> item_ID;
    vector<string> item_name;
    vector<double> ordered;
    vector<double> stock;
    vector<double> sold;
    vector<double> m_price;
    vector<double> o_price;
    ifstream in;
    ofstream out;

    in.open("c:\\a9data.txt");

    input(in, out, item_ID);
    system("pause");
}

void input(ifstream& in, ofstream& out, vector<double>& item_ID)
{
    in.open("c:\\a9data.txt");
}

Cool story, bro.

vectors are totally gay

can anyone see my error? copy paste replicate?

Help us help you.  Moron.

Definition:
void input(ifstream& in, ofstream& out, vector<double> item_ID);
Implementation
void input(ifstream& in, ofstream& out, vector<double>& item_ID)

Your function declaration defines a vector<double> but your function definition uses the address of a vector<double>.  Can you do that?

Sorry, messed up the headers for the quotes even after making sure I used the right words for the comments.  The top is "Declaration;" the bottom should be "Definition."

>>7
right on the money, it was my prototype that was the problem. now i have to actually get back to work :/
thanks bro.

:-(

Why are you doing this?

Every time I need to debug something I'm going to create a new thread.

Don't forget to deindent your code next time!

>>11
deindent? it's not intended in the first place!

    in.open("c:\\a9data.txt");

    input(in, out, item_ID);

void input(ifstream& in, ofstream& out, vector<double>& item_ID)
{
    in.open("c:\\a9data.txt");
}

void input(ifstream& in, ofstream& out, vector<double>& item_ID)
try
void input(ifstream* in, ofstream* out, vector<double>* item_ID)

Fucking newb, learn difference between

void input(ifstream& in, ofstream& out, vector<double> item_ID);
and
void input(ifstream& in, ofstream& out, vector<double>& item_ID)

Also system("pause") is shit-tier

system("pause") is bro tier

>>15
He's right, guys.

>>16
Can go kiss my ass.

If you want to read the output of your program without your "CMD.COM", either run the program manually from "CMD" or YOU CONFIGURE YOUR IDE CORRECTLY...

The latter should be possible with visual anus, right?
