Do you know what "argc" is supposed to be, and more importantly, what it means? What is the argument count (argc) value when you get to that line of code? It obviously isn't 3, so you need to...

That is because you are not stepping into the program with F10.
Why are you putting a break at the end of the program? You're supposed to place a breakpoint at the beginning of the main()...

Have you run the code you've posted? If not, then why not run it first to determine the flow of the program, instead of trying to eyeball multiple screensworth of code?
