extracting a string between two patterns

[aliyesami]

I have a 100 chars wide string with few '\n' characters, I want to extract the string between the first and the second '\n'.
how can I do it without using streams or vectors as I am using AVR GCC .

This is an extremely simple programming exercise. Give it a shot.

strchr is what you need.

EDIT

Easier would actually be strtok.
