When Dave started talking about this:
int main (int argc, string argv )
I had zero idea what he was going on about. Now I think I understand a little more.
This is just to allow you to add things to the command line, instead of running the program then adding things.
All about efficiency…I guess?
argc // Lets you count the characters you add. // EG. Hello has 5 characters. string argv  // Lets you add a word
Man… this thing [ ] still confuses me??
