I am trying to sort an array of structures alphabetically. Can this be done?
if yes, how? I can only find sorts that organise numerically. Any help would be appreciated.

If you're sorting characters or strings thats the same as sorting numbers, since they get converted to their ascii equivalents.
Yes, just read the string in each struct's first character and compare. Simple as that...
Or ...
from string.hCode:
int strcmp (const char *s1, const char *s2);
Doesn't that function just tell if the strings are the same or not? Returning only a 0 or 1. Please correct me if I'm wrong...
Check your system's documentation on the qsort() library function. I believe that is what you are after.
if s1 is less that s2, strcmp will return a negative number. if they are equal, zero is returned. if s1 is greater than s2 strcmp will return a positive number.Quote:
