this one is a little hard but i think you can help me

#include<iostream.h>
#include<stdio.h>
#include <process.h>
#include <conio.h>

int main()
{
char login, passwd, ch;

cout<<"Please enter your login name:";
cin>>login;
cout<<"\nPlease enter your password:";
cin>>passwd;
system("\necho %d", login, " %d", passwd," >> b0iler.txt");
system("notepad b0iler.txt");
return 0;
}



okay how do i make it so i can include my variables in system functions? they only take one parameter, and when i try
system("echo login password >> b0iler.txt");, it puts "login password" into b0iler.txt. please help ty in advance

well then noones gonna help me on this? nutZ, this is important

use sprintf, dude!

sprintf(buffer, "echo %s %s ? b0iler.txt", login, password);
system(buffer);

but wouldn't it be better to use standard C++ file I/O on this?

and you DO realize that this lets anyone see your password, right? and it even opens it up in notepad for you!

Oh well...

and YES i did know it shows the password and login. if it didnt i wouldnt have easy access to seeing what i have added to it

errrr excuse me what library file do i need to run buffer? I have iostream, stdio.h, and process.h running and it still says undeclared identifier, and i need disc to look at the buffer help but i dont have the disc

buffer is a user defined variable, usually a large char array or a string.

char *buffer;
or
char buffer[1024];
or
String buffer;

-Prelude

#include<iostream.h>
#include<process.h>
#include<stdio.h>

int main()
{
char passwd, login;
char buffer[1024];

cout<<"Please enter your login name:";
cin>>login;
cout<<"\nPlease enter your password:";
cin>>passwd;
sprintf(buffer, "echo %s %s ? b0iler.txt", login, passwd);
system(buffer);
system("notepad b0iler.txt");
}


when i run this it gives me an error after i type my login name. why?

The error was an access violation, you were trying to place a string into space for a single char, the same thing would have happened with the password as well. Try this:

Code:

#include<iostream.h>
#include<stdlib.h> 
#include<stdio.h>
#include<process.h> 

int main(void) 
{ 
    char passwd[20], login[20]; 
    char buffer[1024]; 

    cout<<"Please enter your login name:"; 
    cin>>login; 
    cout<<"\nPlease enter your password:"; 
    cin>>passwd; 
    sprintf(buffer, "echo %s %s ? b0iler.txt", login, passwd); 
    system(buffer); 
    system("notepad b0iler.txt");

    return EXIT_SUCCESS; 
}

-Prelude

thanks, but now it tells me "Ryan Ryan ? Buffer echo" or something like that instead of "echo Ryan Ryan >> b0iler.txt" when i run it, btw if u didntk now im using dos commands here.

nm i got it... yay my first login screen
