title: how to tell when you've reached the end of a C array? (specifically argv)
body: <p>been asked a question on this, basically coming up with argc...without actually having argc</p>
  
  <p>if your given argv, which as I understand essentially a array of pointers to the relevant char arrays of each inputted argument, </p>
  
  <p>how would I actually go about counting the number of pointers in argv?</p>
