    Question passgate program

    I just began learning C++ about a week ago and have ran into a very strange problem. I was writing a database program and was adding password protection to it...only problem was, it didn't work. lol. So I made a VERY simple passgate to see what my problem was. About 2 hours later, I'm still working on it and making no real progress. Its kinda embarrasing to ask because its such a simple program, but I just am not seeing the solution.

    #include <iostream.h>
    int passcheck(char password[100]);
    int passcheck(char password[100])
         char correct[100] = "swordfish";
         if (password == correct)
           return 1;
             cout << "\nWhat you typed: " << password;
             cout << "\nWhat you should have typed: " << correct;
           return 0;
    int main()
        char password[100];
        cout << "\nPassword: ";
        cin >> password;
        cout << "\nExiting...";
        return 0;
    What you typed: swordfish
    What you should have typed: swordfish

    Maybe its just me, but I find it odd that it says I've typed in the right password, but that its somehow wrong. Any help would be appreciated.

    If you knew I'd have to kill you
    You can't compare to char arrays like this.
    Take a look at C++ style strings. It will be much easier.
    Also, put the indented statements which are part of the conditional in "{}" brackets
    if (something)
      do something
      do something else
    C++ is not indentation sensitive, so in your above code, the second statement after the else would have gotten executed no matter what.

    You should use c++ strings really, but your prog should work if you change the line
    if( password == correct )
    if( !strcmp( password, correct ) )
