System Command with variables

Hey guys, I'm just starting to get back into C++ Programming, and forget how to call a System Command and input variable values into the command. Currently I am creating a little Internet Utility program, one of the options of the program is to allow the user to delete his/her current gateway route, and add a new one. How ever when creating a new one, you must enter the IP Address you would like to use as well as the network mask and gateway. Here is what I have already, but i know for a fact that it doesn't work.

Code:

---

/*Variables*/
        char IP, mask, gateway;      //user input information
        system("cls");              //clear screen
        SetConsoleTitle("Add Gateway route");            //reset Console title
        cout<<"Please enter IP Address:\n"<<flush; //promted to enter ip address
        cin>>IP;      //enter IP Address
        cout<<"Please enter network mask:\n"<<flush //prompted to enter network mask
        cin>>mask;    //enter network mask
        cout<<"Please enter network gateway:\n"<<flush //promted to enter network gateway
        cin>>gateway; //enter network gateway
        /*Add gateway route*/
        system("route add", IP, mask, gateway);
        cout<<"\n\nPress <ENTER> to continue..."<<flush;        //promted to continue
        cin.get();      //hold screen

---

Thanks in advance

IP, mask, and gateway should be string instead of char. char only holds one character and string can hold more than you'd ever need. :) Since they're strings, you can just add them together into one and then pass that to system():

Code:

---

/*Variables*/
        string IP, mask, gateway;      //user input information
        system("cls");              //clear screen
        SetConsoleTitle("Add Gateway route");            //reset Console title
        cout<<"Please enter IP Address:\n"<<flush; //promted to enter ip address
        cin>>IP;      //enter IP Address
        cout<<"Please enter network mask:\n"<<flush //prompted to enter network mask
        cin>>mask;    //enter network mask
        cout<<"Please enter network gateway:\n"<<flush //promted to enter network gateway
        cin>>gateway; //enter network gateway
        /*Add gateway route*/
        string command = "route add " + IP + " " + mask + " " + gateway;
        system( command.c_str() );
        cout<<"\n\nPress <ENTER> to continue..."<<flush;        //promted to continue
        cin.get();      //hold screen
