Command line arguments What is argc, argv? Here is the code you saw Professor David Malan demonstrate in the videos above. hello-3.c argv-0.c argv-1.c argv-2.c Thought Questions What is the relationship between argc and argv? Specifically, what does argc tell us about how far we can iterate through argv? What is the data type of argv? What is the data type of the elements of argv? What does that mean if the user inputs, say, “18” or “5.22” at the command line? Why might we want to collect information at the command line instead of after the program has started running?
