strlen will give you the length of a string, NOT including the '0円' terminator. It should not be confused with the sizeof operator which returns the size of a variable (that could hold a string).

Library: string.h
Prototype: size_t strlen(const char *s);
Syntax:	 size_t size;
	 char string[20]="red dwarf";
 size = strlen(string);
