Strip first and last character from C string

Question

I have a C string that looks like \"Nmy stringP\", where N and P can be any character. How can I edit it into \"my string\" in C?

Answer 1

Further to @pmg's answer, note that you can do both operations in one statement:

char mystr[] = "Nmy stringP";
char *p = mystr;
p++[strlen(p)-1] = 0;

This will likely work as expected but behavior is undefined in C standard.
