Maybe this is relevant:

Thanks. That looks exactly like the place to start. Also thanks to the
other answers. I assume argc contains the number of (space-separated)
arguments.

The arguments aren't necessarily space-separated; that depends on the
mechanism (for example, a shell) used to invoke your program.

argc is the number of valid elements of the array pointed to by argv.
If you invoke your program with 2 command-line arguments, argc will be 3.
argv[0] probably points to (some form of) the name of your program;
argv[1] and argv[2] point to your command-line arguments.

We must do something. This is something. Therefore, we must do this.
