Precisely backwards. Smilie Nonzero values mean error. You can simplify the expression a lot:

Code:
if(WEXITSTATUS(system("gksudo")))
        cout << "Error\n";
else
        cout << "Success\n";

Ok, thank you so much!!!
I'll try this in a moment and i'll let you know!

---------- Post updated at 02:25 AM ---------- Previous update was at 02:20 AM ----------

Code:
#include <sys/types.h>
#include <sys/wait.h>
#include <stdlib.h>
#include <iostream>
using namespace std;

int main()
{

    if(WEXITSTATUS(system("gksudo")))
            cout << "Error\n";
    else
            cout << "Success\n";
    return 0;
}

Error at line 10: if(WEXITSTATUS(system("gksudo"))) --> lvalue required as unary ‘&’ operand

Code:
#include <sys/types.h>
#include <sys/wait.h>
#include <stdlib.h>
#include <iostream>
using namespace std;

int main()
{
    int lol = system("sudo -i");
    int exitstatus = WEXITSTATUS(lol);
    if(exitstatus)
            cout << "Error\n";
    else
            cout << "Success\n";
    return 0;
}

This works fine. Thanks.

What is gksudo?

Gksudo does exactly what sudo does but it pop-ups a nice prompt. The same prompts that pop-ups when you open synaptic package manager in 10.04
