Question

What are the arguments passed into the main method of a command-line program:

int main(int argc, const char * argv[])

what is the first int mea

Answer 1

The parameters to main() are a unix convention for accessing the arguments given on the command line when your program is executed. In a Cocoa app, you can access them the plain old C way, or you can use NSProcessInfo's -arguments method to get them in an NSArray of NSString objects, or use NSUserDefaults to get them as values in a dictionary.
