argc - is the number of parameters in the command line including
the program name.
argv[] - is the array of parameters passed in the command line.

As JoeC said, it is a pointer to an array of type char.
You can use argc in a for loop to process the argv[] values.

The int main simply means that the program will return an int after
execution. Using 'void main . . .' will work as well, you just don't
have to return a value. (not good if you want to use your program
in a batch file and need to check the error level for taking care of
the problem the program encountered)
