Thread: 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

Hey thanks, i knew about the string thing, sorry about that I was just forgot about it. Thanks i knew that you could ass 'strings' to the system command i just wasn't sure how, thanks again.
