Small problem in password function

[Ch1156]

I have a password function in my encryption program that has the user enter A password so that no one else can unencrypt their stuff but i have one small problem, when you enter the right password it keeps asking you to enter the password. It does it like 3 or 4 times before taking me to the main program, i dont understand why?

Here is the entire code:

#include <iostream>
#include <string>
#include <fstream>
#include <sstream>

using namespace std;

void encrypt()
{
    ifstream fIn;
    ifstream passIn;
    string file_name2;
    string store_text2;
    char lower[27] = {'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','\0'};
    char upper[27] = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','\0'};
    char replace[28] = {'♎','×','♋','¼','Ѝ','☩','þ','ß','¤','Œ','Ø','★','유','½','å','¹','°','Ä','@','¡','♯','^','','♚','*','™','✝','\0'};
    char upperReplace[28] = {'³','²','µ','÷','û','ê','ì','Ñ','Д','Ó','Ö','É','п','⅞','Á','¦','Ü','Û','Ù','Õ','я','Ю','Ã','Ш','₧','Æ','✝','\0'};
    char space = ' ';
    int pos = string::npos;

    cin.ignore(100, '\n');

    cout << "What is the exact name of the file for encryption" << endl;
    getline(cin, file_name2);

    fIn.open(file_name2.c_str());

    stringstream ss(stringstream::in | stringstream::app | stringstream::out);

    while(getline(fIn, store_text2))
    {
        ss << store_text2 << endl;
    }

    store_text2 = ss.str();


    //Find lower case alphabet
    for(int i = 0; i < 27; i++)
    {
        while((pos = store_text2.find(lower[i])) != string::npos)
        {
            store_text2[pos] = replace[i];
        }

        while((pos = store_text2.find(upper[i])) != string::npos)
        {
            store_text2[pos] = upperReplace[i];
        }

        while((pos = store_text2.find(space)) != string::npos)
        {
            store_text2[pos] = replace[27];
        }
    }

    ofstream fOut;

    fOut.open(file_name2.c_str());

    fOut << store_text2;

    cout << "File Encrypted\n" << endl;

    cout << store_text2;

EDIT: When I turned off C++11 it was fine. Nevermind.

EDIT2: Okay, I ran the program, created a password, and when I entered the password, it worked fine! Then I exited and restarted the program, entered my password, worked fine again! Then, it exited on its own (you need to fix that) and the end.

EDIT3: Okay, I fixed the exiting on its own by moving the return 1; passOut.close(); outside the if-else statment. Everything works fine!! Good job!

EDIT4: Okay, the encryptor or decryptor does not work. In a file, I entered :

	lala boo
	
	
	
	boo

And then i encrypted it and decypted it and the output is:

	aaaaaboo
	
	
	
	boo

hmm thats weird i dont get any errors

[18hRX9L8]

check my edits sorry

[Ch1156]

i tried it on my side and it workds just fine, encrypting and decrypting. My program asks for the user to enter their password twice thats my problem im having. Im not exactly sure why the decryptor and encryptor arent working. but i have a theory.

What's your theory?
I am using Orwell Dev C++ with TDM-GCC 4.6.1 if that helps.

[Ch1156]

Well im using Code::Blocks, but my theory is that some of the symbols are non UTF-8 compatible, thats what my compiler tells me, so my theory is that your computer has different hexidecimal codes thatn my computer does for each symbol. But thats just a theory, i have no idea if thats even true ort not.

this has to be a simple problem with the password function but i cant fgure it out dsoes anyone know? Its the only bug thats keeping my program from being complete

The password program works fine for me. I am using ORWELL Dev C++ with TDM-GCC 4.6.1.
