title: Reading string character by character in C
body: <p>So I have a string passed into main function: int main(int argc, char* argv[]) </p>
  
  <p>I understand argc (which is 2 in this case), but don't understand how I can read argv[] character by character?
  When I print argv[0] shouldn't that print the first character in the array of characters for that string?</p>
  
  <p>Thanks</p>
