Doesn't index search for the first occurrence of a particular character
in the string? I think what he's looking for is just the left-most
character everytime, regardless of what it is, which could be done like
this (if you want the rest of the string to go into another variable):
char firstchar;
if ( argument[0] != '\0' )
{
firstchar = argument[0];
argument++;
}
that would first check to see if the user didn't enter an argument, and
if they did, assign the first letter (or number) of that argument to
'firstchar', and then increment the space pointed to by argument so that
if argument == 5678, firstchar would = 5, and argument would then =
678... if you want to use this only for numbers, you can simply add a
check for !is_number(argument) before you split off the values, and spit
out an error message if the entire string isn't a number (i.e. 5678a)...

You can do this with index().
