couldn't you try something like:

#include <iostream>

using namespace std;

int main()
{
    char address;
    address = 'C:\\Program Files\\alcohol soft\\alcohol 120\\AxCmd.exe E: /u'
    system(address);
    system("PAUSE");
    return EXIT_SUCCESS;
}

or even:

(Toggle Plain Text)

#include <iostream>

using namespace std;

#define address 'C:\\Program Files\\alcohol soft\\alcohol 120\\AxCmd.exe E: /u'

int main()
{
    system(address);
    system("PAUSE");
    return EXIT_SUCCESS;
}

or something of that sort... just some thoughts... I'm still a noob at C++ ^_^

@Lich: if you do that, the ~1 trick might not work anymore.

@Yarvin: there are two problems with your solution:
1- '\' is considered an escape character that cannot be used in strings. To use it, we do '\\'.
2- System() will not accept spaces within the command string.

Okay... So I get the escape character, but I don't quite understand the space problem within System(). In my code I'm using a variable in place of the address so there isn't a space in System(). Maybe I just don't understand what you mean by System() not accepting spaces.....

@Yarvin: If you run a command like this in system(),

(Toggle Plain Text)

system("C:\\Program Files\\Cant be read\\CanUReadMe.exe");

your console will complain that

because it thinks that C:\\Program is the file you are trying to open and "Files\\Cant" is the command line arguement you are trying to pass, which is not the case, obviously. The space between Program and Files is the problem. That's what they meant by System() not accepting spaces.

Personally, I don't use the system call, but my guess would be;

(Toggle Plain Text)

   system("\"C:\\Program Files\\alcohol soft\\alcohol 120\\AxCmd.exe\" E: /u");

In short, put quotes into the string around the full name of the executable but NOT around command line arguments. Or (more simply, using forward slashes)

(Toggle Plain Text)

   system("\"C:/Program Files/alcohol soft/alcohol 120/AxCmd.exe\" E: /u");

I am, of course, assuming that AxCmd.exe is in the specified directory.

Oh! Okay I get it now.... Thank you.
so using:

(Toggle Plain Text)

System('"C:\Program Files" E: /u')

wouldn't work?
I figured it would because the autocomplete in the command prompt just surrounds it by a pair of "".

It wouldn't compile, you can't use single quotes around strings in c++.
