How do I find and return first occurence of a alpha character?

[Chucklez]

I took classes in C years ago, and have forgotten most everything I learned from them. Now I find myself in need of a simple str function.

Here is a sample bit of data:
1A-01
12C-15
8B-08
9C-05

What I need to do is return the first occurence of a non-numeric value, or basically return the letter value.

So in the first data, 'A' will be returned, then 'C', then 'B', etc. How do I do use. the str function seems to be were I need to go, but I dont know for sure.

Thanks for the help,
Chucklez

You may be looking for the [tt]strcspn[/tt] function.

Or write your own: Walk through the array with a loop, checking each character with isalpha() (ctype.h) and '\0'.

Something like:

char *p = mystring;

while isalpha (*p) == 0 and *p != '\0'
  Increment p

If *p != '\0' Then *p must be alpha
