Webbargc is the number of arguments being passed into your program from the command line and argv is the array of arguments. You can loop through the arguments knowing the number of them like: for (int i = 0; i < argc; i++) { // argv [i] is the argument at index i } Share Improve this answer edited Aug 23, 2016 at 19:52 Peter Mortensen 31k 21 105 126 Webb1 aug. 2012 · argv [1] [0] refers to the 1st character of the 2nd string. relies on the languages short circuit evaluation to safe-gaurd the array dereference.In other words if the the test argc == 1 fails then the subsequent expression argv [1] [0] is not evalauted.
