How to split one command line argument

I have a C program that takes a command line argument like this:
myprogram 5.100.3.6

or called from a web browser:
myprogram?5.100.3.6

I need to be able to separate the four numbers and put them in separate variables, like this:

p should have the value 5
a should have the value 100
w should have the value 3
pg should have the value 6

Hou do I do it? I can go so far as to have a variable that holds the entire thing "5.100.3.6" using the form main(int argc, char **argv), but I can not figure out how to split it. If I would use PERL I would do it like this:

@argument = split(/\./, $ARGV[0]);

but in C .... I don't know. Please help.

Thank you.

This should work (man sscanf(3)):

--//--
int p, a, w, pg;

sscanf(argv[1], "%d.%d.%d.%d", &p, &a, &w, &pg);
--//--

(note that in C argv[0] contains the commund run)
