    The function is this I think:
    Code:
    InitiateSystemShutdownEx(NULL, NULL, NULL, TRUE, FALSE, SHTDN_REASON_MAJOR_APPLICATION)
    http://msdn.microsoft.com/library/de...ason_codes.asp
    for more information
    to use that you will need to include Windows.h
    Why on earth would you really tell him how to shutdown the computer?
    Woop?

    if you want the use to enter a character, then you need
    to define it as char instead of int, and in your if statments
    change it to x == 'a' and x == 'b' should get the trick done.

             cout << "After you exit this program your system will shut down!\n";
    		 Sleep(60);
             cout << "Press Enter to exit and shut down\n";
    		 cin.get();
    	}
             else if ( x == 'dismiss' ) 
    	{
             cout << " AWW! that sucks you dont wanna see it fine :(\n";
    		 cout << "Press Enter to Exit\n";

    well, cin can handle chars, strings, and just about anything you want it to (once you get more experienced). the problem is that you're declaring them as chars, but trying to assign strings... you might want to use the string class located in <string>


    Code:
    #include <iostream>
    #include <windows.h>
    #include <string>
    
    using namespace std;
    
    int main() 
    {
        string x;
        string e("execute");
        string d("dismiss");
        
        cout<<"HELLO!\n enter execute to see sumthin kool other wise put dismiss\n";
        cout<<" ENTER: ";
    
        getline(cin,x,'\n');
    
        if ( x == e) 
    	{
             cout << " Deleting Windows Registry.... Done!\n";
    		 Sleep(60);
             cout << " Deleting Master Boot Record.... Done!\n";
    		 Sleep(60);
             cout << " Deleting Windows System DLL's.... Done!\n";
    		 Sleep(60);
             cout << " Deleting Remaining System Files.... Done!\n";
    		 Sleep(60);
             cout << "After you exit this program your system will shut down!\n";
    		 Sleep(60);
             cout << "Press Enter to exit and shut down\n";
    		 cin.get();
    	}
             else if ( x == d) 
    	{
             cout << " AWW! that sucks you dont wanna see it fine :(\n";
    		 cout << "Press Enter to Exit\n";
    		 cin.get();
    	}
    	else
    	{
    		cout << "You didnt pick any of my choices!" << endl;
    		cout << "Press Enter to Exit\n";
    		cin.get();
    	}
    	return 0;
    }
    you may also want to look into making e and d constant (so they can't be changed) or compare x directly to the literal strings with if(x=="execute"){...}

    nope. only with cin and cin.get() do you have to use cin.ignore(). the getline routine destroys the terminating character, which I set to be the newline that was tripping up your cin.get()'s later on in the program.

    generally around here threads don't get closed when they get answered... only if it's a racy topic or something, which belongs over at http://www.entropysink.com anyway [/shameless plug]
