Writing vectors to ofstream

[omn0mnomm]

So I'm working on a program to encrypt a file by reading a file, adding 8 to the ACSII code, and writing it to a second file. I've never done casting before so this could be completely wrong. It runs without errors but doesn't write anything to the Encrypt.txt and doesn't confirm the password. It just asks for the password and pauses the system. Please help :(

#include <iostream>
#include <fstream>
#include <vector>
#include <algorithm>
#include <iterator>
#include <string>

using namespace std;

//Encrypt by adding 8 to each value of vector
void encryption(vector<int> out, ifstream& encrypt, ofstream& decrypt)
{
	int ACSII, x;
	char text1,text2;
	int i = 0;
	vector<char> in;

	//Read file and put into vector
	while (!encrypt.eof())
	{
		encrypt >> text1;
		//Convert char to int
		ACSII = (int)text1;
		//Add 8
		x = ACSII + 8;
		//Convert back
		text2 = (char)x;
		out.push_back(text2);
	}

	//Write encrypted file
	copy(out.begin(), out.end(), ostream_iterator<float>(decrypt));
}



//Print decrypted contents
void print(ifstream encrypt)
{
	string line;
	while (!encrypt.eof())
	{
		getline(encrypt, line);
		cout << line << endl;
	}
}



int main()
{
	ifstream password, encrypt;
	ofstream decrypt;
	string pass, entry;
	vector<int> out;

	//Open File.txt
	encrypt.open("G:\\College\\2016 Spring\\C++\\Final\\File.txt");
	if (!encrypt)
	{
		cerr << "Unable to open file. \n";
		system("pause");
		return 1;
	}

	//Open Encrypt.txt
	decrypt.open("G:\\College\\2016 Spring\\C++\\Final\\Encrypt.txt");
	if (!decrypt)
	{
		cerr << "Unable to open file. \n";
		system("pause");
		return 1;
	}

	//Call encryption function
	void encryption(vector<int> out, ifstream& encrypt, ofstream& decrypt);

	//Open password file
	password.open("G:\\College\\2016 Spring\\C++\\Final\\Password.txt");
	if (!password)
	{
		cerr << "Unable to find password. \n";
		system("pause");
		return 1;
	}

	//Get password into char data type
	getline(password, pass);

	//Ask for password
	cout << "Please enter password: ";
	cin >> entry;

	//Confirm password
	if (entry == pass)
	{
		//Call print function if password is correct
		void print(ifstream encrypt);
	}

	if (entry != pass)
	{
		cout << "Incorrect.";
	}

	password.close();
	decrypt.close();
	encrypt.close();

	system("pause");
	return 0;
}

	//Call encryption function
	void encryption(vector<int> out, ifstream& encrypt, ofstream& decrypt);

Not a function call

Here's an example of a function call getline(password, pass); note how the parameters are written.
