Log in Programm in C programmieren

[dreamweaver2004]

Hallo,

ich muss ein Log in Programm in C programmieren.
Es hat leider einen Fehler.

Hier erstmal der Code:

#include <stdio.h>
int checkPassword (char acEnteredPassword[], char acRealPassword[], int iLengthPassword);
int checkName (char acEnteredName[], char acRealName[], int iLengthName);
int main()
{
    char acEnteredPassword[1000];
    char acRealPassword[] = {'1','2','3','\0'};
    char acEnteredName[1000];
    char acRealName[] = {'U','s','e','r','\0'};
    int iLengthName = sizeof (acRealName);
    int iLengthPassword = sizeof (acRealPassword);
    int iNameRight;
    int iPasswordRight;

    printf ("Please etner your log in name: ");
    gets (acEnteredName);

    printf ("\nPlease enter the Password: ");
    gets (acEnteredPassword);

    checkName (acEnteredName, acRealName, iLengthName);
    if (iNameRight)
    {
        printf ("\nThe log in name is right!");
    }
    else
    {
        printf ("\nThis is the wrong log in name!");
    }

    checkPassword (acEnteredPassword, acRealPassword, iLengthPassword);
    if (iPasswordRight)
    {
        printf ("\nThe password is right!");
    }
    else
    {
        printf ("\nThis is the wrong password!");    
    }

    printf ("\n\n\n\n");

    system ("pause");

    return 0;
}

int checkName (char acEnteredName[], char acRealName[], int iLengthName)
{
    int iCount;
    int iNameRight = 1;
    int aiLetter[100];

    for (iCount = 0; iCount < iLengthName; iCount = iCount + 1)
    {
        aiLetter[iCount] = acEnteredName[iCount];
    }
    return iNameRight;
}            

int checkPassword (char acEnteredPassword[], char acRealPassword[], int iLengthPassword)
{
    int iCount;
    int iPasswordRight = 1;

    for (iCount = 0; iCount < iLengthPassword; iCount = iCount + 1)
    {
        if (acEnteredPassword[iCount] != acRealPassword[iCount])
        {
            return 0;
        }
    }
    return iPasswordRight;
}

Warum ist die Ausgabe immer right?
Bitte helft mir.
Es ist sehr dringend!

iPasswordRight wird uninitialisiert benutzt, ich vermute mal du wolltest schreiben iPasswordRight = checkPassword(...);
