Ich benötige einfachen Kennwort Script, Hilfe??

[3mu180r]

thank you for that example, couple questions though:

first here is my \1:

// new.cpp : Defines the entry point for the console application.
//

const char *passwd = "my_password"; 
string password;

   //...handle events for user-input -- ??

   //button-click-event -- ??

if(password != passwd) {
      printf("Wrong");
} else {
     printf("Correct");

}

I placed ?? where I have no idea of what to do.. I attempted to type something logical to show you what I'm trying to do.. this simple program will be purely for my own education, and will be a great example to learn from, if someone could add to it for me, I would be very grateful.. thanks in advance

I thought that you using the mfc or winapi and that you made a gui. But in this
case i misunderstood something, sry.

Because you write a console program you can just ignore and delete the comments
i made related to some events.

A simple program with user login:

bool checkPasswd(std::string &password) {
    if(password == passwd)
        return true;
    return false;
}

int main() {
    std::cout<<"first login to get the result of 1 + 1 ;): ";
    std::string userPasswd;
    std::cin >> userPasswd;

        if(checkPasswd(userPasswd))
             std::cout<<"\n"<<1 + 1<<"\n";
        else
             std::cout<<"\nAccess Denied!\n";

    return 0;
}

Of course this program is just an example.

I guess this example should makes it clear

@vR: maybe you can tell us also something about the definition of 'passwd'

[3mu180r]

man I keep trying to compile this but it keeps saying:

fatal error C1010: unexpected end of file while looking for precompiled header directive
Error executing cl.exe.

#include "cdosysstr.h"

bool checkPasswd(std::string &password) {
    if(password == passwd)
        return true;
    return false;
}

int main() {
    std::cout<<"first login to get the result of 1 + 1 ;): ";
    std::string userPasswd;
    std::cin >> userPasswd;

        if(checkPasswd(userPasswd))
             std::cout<<"\n"<<1 + 1<<"\n";
        else
             std::cout<<"\nAccess Denied!\n";

    return 0;
}

any ideas why?? thanks

[SideWinder]

#include <iostream>
#include <string>

Best regards,

[SideWinder]

And try:

std::getline(std::cin,userPasswd);

instead of:

std::cin >> userPasswd;

...too late
but still: where is the definition of 'passwd'? in cdosysstr.h??

[3mu180r]

I am horrible at this, I made the changes you suggested and it is still giving me the same error, he makes a good point, I haven't any idea how to define the header.. this will be my first attempt at C++ programming, so sorry for all the lame questions, however I know if I can get this working I will learn alot from it.. so, help is much appreciated..

here's my current attempt:

// kok.cpp : Defines the entry point for the console application.
//
#include <iostream>
#include <string> 

bool checkPasswd(std::string &password) {
    if(password == passwd)
        return true;
        return false;
}

int main() {
    std::cout<<"first login to get the result of 1 + 1 ;): ";
    std::string userPasswd;
    std::getline(std::cin,userPasswd);

        if(checkPasswd(userPasswd))
             std::cout<<"\n"<<1 + 1<<"\n";
        else
             std::cout<<"\nAccess Denied!\n";

    return 0;
}

thanks

[SideWinder]

Would be nice if you post the compile-error-messages!

freshman is right, the string "passwd" isn't defined. Just add this at the beginning from the checkPasswd() function:

std::string passwd = "secret";

Best regards,
SideWinder

[3mu180r]

is this what you meant for me to do:

// kok.cpp : Defines the entry point for the console application.
//
#include <iostream>
#include <string> 

bool checkPasswd(std::string passwd = "secret"; &password) {
    if(password == passwd)
        return true;
        return false;
}

int main() {
    std::cout<<"first login to get the result of 1 + 1 ;): ";
    std::string userPasswd;
    std::getline(std::cin,userPasswd);

        if(checkPasswd(userPasswd))
             std::cout<<"\n"<<1 + 1<<"\n";
        else
             std::cout<<"\nAccess Denied!\n";

    return 0;
}

this isn't working either.. here is my errors:

where's the problem?

#include<iostream>

bool checkPasswd(std::string &password) { 
	std::string passwd = "secret"; 
    if(password == passwd) 
        return true;

} 

int main() {

    std::string userPasswd; 
    std::getline(std::cin,userPasswd); 

        if(checkPasswd(userPasswd)) 
             std::cout<<"\n"<<1 + 1<<"\n"; 
        else

@freshman: Er hat aber etwas anderen Code.

@3mu180r: Change to freshman's version

thank you very much, I will certainly learn alot from refrencing this script, you guys are awesome, thanks again

Ne, aber du kannst um diese Uhrzeit nicht von mir erwarten, dass ich schon
gutes Englisch schreibe :D.

Oder wuerdest du sagen, dass google es _noch_so_gut_ hinbekommen haette?

@vR n' SideW: warum eigentlich
bool checkPasswd(std::string &password)
und nicht call-by-value oder Übergabe von konstantem Obj (read-only-Bez) ??

stimmt! Aber es war dein zweiter Post und nicht dein 'erste'

[SideWinder]

"const std::string&" wäre in diesem Fall wohl am Besten. Ein String hat meistens mehr als 4 Zeichen + meistens 4 Bytes für die Länge macht schon 8 Bytes wenn du per value übergibst.

Per Reference sinds nur 4 Bytes und keine aufwendigen Kopieroperationen. Da der String trotzdem nicht verändert werden soll macht man ein const davor.

Stimmt, ein

bool checkPasswd(const std::string &password);

waere schoener gewesen. call-by-value hab ich nicht gemacht, weil ich es als
unnoetig angesehen habe, dass hier ein Objekt kopiert werden muss.
