Hi everyone! How's it been?
Walter my man...I see you're still hard at work!
Matthew...I see the Journal is progressing a little slower than we'd
like...patience my brother, it will all come together when the time is
right.  Just be ready to capitalize when that time does arrive.

Pavel, Anderson, Carlos, Sean and the rest of the gang (too many to name),
thanks for keeping the ideas flowing and preventing Walter from going into
shellshock.

I've just returned from training and am happy to see you guys still
plugging at it.

I'm wandering if someone could help me out a little?
The following is an example that Walter provides with the compiler.  Fairly
simple no doubt, however my "pre-processor" (translation: feeble brain) is
not making all the right connections between code and output.

int main(char[][] args)
{
    printf("hello world\n");
    printf("args.length = %d\n", args.length);
    for (int i = 0; i < args.length; i++)
 printf("args[%d] = '%s'\n", i, (char *)args[i]);
    return 0;
}

I understand what it does but not how or why it does it!
I'm completely lost on the "int main (char[][] args)" thing since cannot
come up with an equivalent C++ example.  From what I've learned (first C++
class during the summer) you start your programs with int main() or int
main(void).  I've got a long way to go, but this would help out allot.

Thanks.

 main(void).  I've got a long way to go, but this would help out allot.

This C/C++ program does the same:

#include <stdio.h>
int main(int argc,char *argv[])
{
    int i;
    for (i=0;i<argc;i++)
        printf("%s\n",argv[i]);
    return 0;
}

In C (and C++) the main function takes two parameters: an integer
representing the number of arguments passed to the program, and array of
char* which contains those arguments. You can omit them, and that's probably
what you've learned.
In D, the main function only takes one parameter: an array of strings which
contains the arguments passed to the program. Since arrays have the length
property, there's no need to specify how many they're.
I hope that helps.

 Thanks.

Thanks Carlos,

Hmm, in an ideal non-existent C++, the function header could be :

int main(vector<string> args)
