I checked the site just now and there's this small piece of pseudo-code
"# FOR ACCEPTING MORE THAN ONE ARGUMENT". It's not a very good idea.
What if you want to accept three arguments? How much code are you going
to write if you want (ever) to accept more? What you want is a loop to
go through the argv array, one element at a time. Something like:

---%<--->%---
int main (int argc, char **argv) {
    for (int i = 1; i < argc; i++) {    // For each argument ...
        if (argv[i][0] == '-') {        // Only if it's an option 
(starts with -) 
            switch (argv[i][1]) {       // Check char after "-".
                case 'c':
                    cout << "Option c!" << endl;
                    if (argc > i + 1) {
                        cout << "Argument: " << argv[i + 1] << endl;
                        i++;
                    }
                    else {
                        cout << "Expected argument. Found none." << 
endl;
                    }
                    break;

                case 'e':
                    cout << "Option e!" << endl;
                    cout << "No argument needed!" << endl;
                    break;

                default:
                    cout << "Unknown argument: " << argv[i][1] << endl;
                    break;
            }
        }
        else {
            cout << "Extra arg: " << argv[i] << endl;
        }
    }

    return (0);
}
---%<--->%---

Try it with inputs: (program assumed to be called "test_argv"):

./test_argv
./test_argv abc
./test_argv -c
./test_argv -f
./test_argv -c abc
./test_argv -c abc -e
./test_argv -c abc -e -f def

 char *_SwitchStatementSavedString; //So long as not
 to ever be used as a normal variable name by you or
 another person
 #define SWITCH(x) _SwitchStatementSavedString=x; for
 (;;)
 #define CASE(x) if
 (strcmp(_SwitchStatementSavedString, x)==0)
 Then you use it as follows:
 
 SWITCH(argv[1])
 {
     CASE("-c")
     {
         //Do stuff for this arg
         break;
     }
     CASE("-a")
     {
         //Do something else
         break;
     }
 }
