I know for sure that there are two command-line arguments in C -- argc and argv[], but while taking an online test, I figured out that there are 3 command line arguments in C. Can someone please explain to me this.

    Your use of the term "command-line arguments" is mildly confusing. You are probably thinking of "how many arguments are there to the `main()` function?" — in which case you should see [What should `main()` return in C and C++?](https://stackoverflow.com/questions/204476/what-should-main-return-in-c-and-c/18721336#18721336) for the details. Note that Annex J of the standard recognizes a variant `int main(int argc, char **argv, char **envp)`. Apple provides a fourth parameter, `char **apple`. Etc. – Jonathan Leffler Jul 30 '19 at 04:41

As many as you want. argv[] is a char* array of all of the arguments passed and argc is an integer count of the elements in argv[]. Related TutorialsPoint article
