command line parameters problem...

Hi, I am trying to get this program to take some command line arguements like -l for logging. The problem is my program does not seem to think argv[4] == "-l". Here is my arg check:

Code:

---

/*Check args*/
    if(argc < 4 || argc == 5 || argc > 6 || (argc == 6 && argv[4] != "-l")){
            cerr << "Incorrect set of parameters(" << argc <<") Usage: sqltest new_file.txt [-load|old_file.txt] database.db [-l log.txt]\n";
            exit(1);
    }

---

and here is my input:

Code:

---

sqltest NEW.txt -load new.db -l logfile.txt

---

I removed this from my if statement:

Code:

---

(argc == 6 && argv[4] != "-l")

---

and it worked so I am pretty sure I am missing something about comparing command line args to const char*. The same thing is happening when I check argv[2] for "-load" as well.
thanks

You're looking for strcmp.

Or if you use the C++ string class:

Code:

---

std::string(argv[4]) != "-l"
